Professors at Erfurt [history]

Breithaupt, Joachim Justus (1658-1732)

1687: Professor of Philosophy (Erfurt).

See Halle.

1798: Deacon of the Kaufmannkirche (Erfurt).

1803: Consistory advisor and Superintendant (Heiligenstadt).

1816: Consistory advisor and Superintendant (Erfurt).

Christian Gotthilf Martin Herrmann (also: Hermann), born 8 February 1765 in Erfurt, was the youngest child of a merchant; he died suddenly on 26 August 1823 while on church business at Weissensee. He was a minor theologian and pedagogue, and an early admirer of Kant's aesthetics.

Herrmann attended the Raths-Gymnasium in Erfurt, and then studied theology for several years at the university in Erfurt before transferring to Göttingen. He served as a catechist at the girl's school in Erfurt (1789), but began offering private lectures on aesthetics the following year at the university after receiving his magister’s degree. These lectures were the first of their kind at Erfurt and were quite popular, leading to his promotion to associate professor of philosophy that same year (1790) at both the university and at his old gymnasium. In 1791 he was made deacon of the Reglerkirche in Erfurt, and was promoted to full professor at the gymnasium in 1792. Since 1798 he served instead as deacon of the Kaufmannkirche (Erfurt), but was called to Heiligenstadt in 1803 or 1805 as consistory advisor and general superintendent of the schools there, assuming those same offices in Erfurt when he returned in 1816.

In a pamphlet advertising his lectures on aesthetics at the university of Erfurt (1791), Herrmann compared the aesthetic doctrine in Kant's Critique of Judgment with that found in Frans Hemsterhuis's Letter on Sculpture (1769). Hemsterhuis (1721-90) was a Leiden philosopher whose letter was receiving considerable attention in Germany (for instance, Moses Mendelssohn, J. H. Merck, and Christian Garve all discussed it in print). Herrmann found the two positions similar on many points, but he defended Kant's definition of beauty over Hemsterhuis's, and sent a copy of this pamphlet to Kant (with an accompanying letter dated 10 February 1791). Hemsterhuis had developed an interesting, empirically-based definition of beauty as that which evokes or allows us to grasp the greatest number of ideas in the shortest period of time, but Herrmann noted that this definition concerned a non-aesthetic effect of beauty, rather than the nature of beauty itself, and thus that Hemsterhuis had said nothing about the actual content of aesthetic ideas. Herrmann argued that a thing is beautiful just if it evokes aesthetic ideas, not merely if it enables a swift comprehension of ideas in general. He also published a critical study of Christianity (1792), and later a well-received textbook for religious instruction in secondary schools (1796).

1769-72: Prof. at Erfurt.

1786 (Dec 7): Member of the Berlin Academy of Sciences.

Born (Sep 5) in Bieberach, died (Jan 20) in Weimar. A poet, classicist, and man of letters. His teaching career at Erfurt was brief. Closely associated with the court at Weimar. Founded and edited the important journal of literature, Der Teutsche Merkur (Frankfurt and Leipzig, 1773-1789). Published the first German translations of many of Shakespeare’s plays (1762-6). His daughter Susanna married Karl Reinhold [bio] in 1785, not long after Reinhold’s arrival in Weimar. When Purgstall visited Kant in 1795, he thought Kant resembled Wieland: “You will be amazed who I think Kant resembles; in his wide-ranging speech, in his long parenthetical remarks, sometimes even in his language — with — the crazy Wieland!”[1] Kant and Wieland were inducted into the Berlin Academy of Sciences on the same day. [Letters: 73, 73A, 74, ++++] [Sources: ADB]

Professors at Frankfurt an der Oder [history]

Abbt, Thomas (1738-1766)

1756: Matriculates at Halle.

1758: Magister (Halle).

1760: Assoc. Prof. of Philosophy (Frankfurt/Oder).

1761 (May-Oct): In Berlin with Nicolai and Mendelssohn.

1761 (Nov): Full Prof. of Mathematics (Rinteln).

Thomas Abbt was born (25 Nov 1738) in Ulm, and died (3 Nov 1766) in Bückeburg as court counselor to Count von Schaumburg-Lippe (Abbt’s successor to this post would be Johann Gottfried Herder — who both profited from and promoted Abbt’s work).[1] Abbt was an historical and popular author, and a friend of Moses Mendelssohn, who dedicated his Phädon to Abbt’s memory.

Abbt taught briefly as a lecturer, and then associate professor, at Frankfurt/Oder, before leaving for a position at Bückeburg, also holding a professorship of mathematics at nearby Rinteln — roughly midway between Hannover and Bielefeld, and a good 350 km. west of Berlin, where his heart and mind longed to be. Gottlieb Schlegel [bio] recalls how Abbt, presumably while still at Frankfurt, would present his history lectures as speeches, delivering them from memory with his hat under his arm. 

Abbt received early recognition for his Death for the Fatherland (1761), written in the context of the many deaths suffered by Prussian soldiers during the Seven Years War, although his best known publication is Vom Verdienste (1765).[2] Abbt was Lessing’s successor as reviewer for Nicolai’s Briefe, die neueste Literatur betreffend (Germany's most important journal for literary criticism during its six year span between 1759 and 1765), and also wrote essays for the Allgemeine Deutsche Bibliothek. In July 1764 Nicolai published in his Briefe an exchange between Abbt and Mendelssohn on Spalding’s famous Betrachtung über die Bestimmung des Menschen (1748, and at the time in its 7th edition). Mendelssohn took Spalding’s position that the imbalance between virtue and happiness strongly supports the existence of an afterlife in which the virtuous receive their reward and the vicious their punishment. Abbt, for his part, saw the record of human history as suggesting anything but a providential God and a rectifying afterlife, and (in a manner reminiscent of Hume) argued that only revelation could give us grounds for such a belief; reason points in the opposite direction.

Abbt also wrote a brief biography of Alexander Baumgarten, from whose textbooks Kant lectured. [Sources: Schlegel 1790, 239; Meusel; ADB; Zaremba 1998; Zammito 2002, 163-71] [last update: 30 Jan 2007]

[2] Kant mentions this work in his anthropology lectures (Collins 1,WS 1772/73, Ak. 25:118): "Man hat Bücher von einem großen Man überhaupt Z. B. Abbts Buch vom Verdienst."

Baumgarten, Alexander Gottlieb (1714-1762)

1737: Assoc. Prof. of Philosophy (Halle).

1740-62: Full Prof. of Philosophy (Frankfurt)

Alexander Gottlieb Barmgarten was born (17 Jul 1714) in Berlin and died (26 May 1762) in Frankfurt/Oder, where he was a professor of philosophy. He was the fifth of seven sons; the oldest brother was Siegmund Jacob Baumgarten (Halle; see), under whom he studied Latin and Wolffian philosophy at Halle. He married twice, the second to Justina Elisabeth Albinus, in 1748. In August 1751 he became ill with tuberculosis, which eventually killed him at the age of 48.

Baumgarten is often referred to as the most Leibnizian of Christian Wolff’s disciples,[1] and is best known for his work on aesthetics (1750-58). Kant used his highly successful textbook on metaphysics (Metaphysica, 11739, 71779) for most of his teaching career, as well as the Ethica philosophica and Initia philosophiae practicae primae texts in his moral philosophy lectures.

In the New Elucidation (1755) Kant characterized “the penetrating Baumgarten” [Ak. 1:397] as the “chief of the metaphysicians” [Ak. 1:408]; in his lecture announcement for WS 1765/66, Kant praised Baumgarten’s metaphysics text for “the richness of its contents and the precision of its method” [Ak. 2:308]; in a letter to Herz (24 Nov 1776) Kant counted Baumgarten among “our greatest analysts” alongside Mendelssohn and Garve (Ak. 10:198); in the an-Pölitz 3.1 (logic; dated c.1780), Kant said of Baumgarten that “Wolff’s logic was distilled by Baumgarten, a man who has contributed much here” (Ak. 24:509); and in an-Starke 1 (anthropology; dated 1781/82), Baumgarten is characterised as “a man quite rich in material and succinct in its execution” (Ak. 25:859).

G. F. Meier (1718-1777), a former student of Baumgarten’s, translated his Metaphysica into German (1763), a task that an early death prevented Baumgarten from doing himself. [Sources: ADB; NDB; Niggli 1999; see also Mirbach’s Baumgarten website] [last update: 31 Jan 2014]

Johann August Schlettwein was born (8 Aug 1731) in Weimar, and died (24 Apr 1802) in Dahlen (Mecklenburg). Schlettwein was Germany's foremost physiocrat, a school founded by François Quesnay on the principles of laissez-faire economic transactions and an understanding of wealth based on land. Schlettwein earned a minor footnote in Kant circles for his hope to overthrow the Kantian system in a public exchange of letters. [writings]

Schlettwein attended the Gymnasium in Weimar before studying law and political economy at Jena, where he received a Magister degree. His early writings ranged from logic and metaphysics to theology and the natural sciences (see ADB). He received a government post in Baden in 1763 as Kammer- und Polizeirath (and later as Hofrat). The Markgraf of Baden was a strong proponent of physiocracy and founded a society in 1765 to promote its principles in Baden. 

Schlettwein fell out of favor with the Baden court in 1775 and moved to Vienna, then taught briefly at Basel before beginning an eight-year career as a professor of political economy at Giessen, where a new economics faculty had been formed. In 1785 he moved to the estate of his wife’s family in Mecklenburg and taught at the university at Greifswald.

Johann Georg Heinrich Feder was born (15 May 1740) in Schornweißach (near Neustadt) and died (22 May 1821) in Hannover. His father was a pastor. Feder was a professor of philosophy at the university of Göttingen and a founder of the German Popularphilosophie; he was influenced by British empiricism and was a forceful critic of Wolffian rationalism. Along with Kraus in Königsberg, Feder helped introduced Adam Smith’s Wealth of Nations (1776) to a German audience. His New Emile (1768-71) was based on his time as a private tutor (and referring, of course, to Rousseau’s Émile, 1762), as well as his Grundriß (1767), which brought him the recommendation of Prof. Ernesti (Leipzig; see) for a professorship at Göttingen. Feder wrote two other highly successful textbooks, besides the Grundriß (which Kant used in his lectures on Philosophical Enzyclopedia during the late 60s-early 80s): a text on ethics (1770) and on logic and metaphysics (1769), which Kant’s colleague Buck used at Königsberg. Feder also edited the Göttingische gelehrte Anzeigen. The only correspondence between Feder and Kant occurred in early 1779, when Kant was apparently looking for a teaching position for his student C. J. Kraus.[1]

Perhaps the most significant event connecting Kant and Feder was the unfortunate review of Kant’s Critique of Pure Reason, written primarily by Garve but edited and published by Feder in the Göttingen Gelehrten Anzeigen (1782).[2] This caused a rift between Kant and Feder that never healed. Feder replied to Kant’s Prolegomena (1783) with On Space and Causality (1787), and with Christoph Meiners published four volumes of the anti-Kantian Philosophische Bibliothek (1788-91).

Gatterer was born into modest circumstances (Jul 13) in Lichentau (by Ansbach) and died (Apr 5) in Göttingen, where he had taught for forty years as a professor of history. With his collague A. L. Schlözer (1735-1809), Gatterer developed a modern hermeneutical approach to historical knowledge that viewed cultural and individual perspectives as unavoidable. Rather than offering a merely chronological ordering of events, Gatterer aimed to write history 'pragmatically', meaning that events were to be systematized by describing their causal relations and thus by representing the 'universal connection of things in the world' (nexus rerum universalis) (1767, 85). With this he hoped to bring the past before the understanding as though it were part of the intuited present. In all, Gatterer attempted six universal histories, although his most enduring contribution was his developing into modern sciences several historical ancillary disciplines: genealogy, heraldry, diplomacy, and physical geography. A longer biography of Gatterer is also available.

Born (Nov 7) in St. Gallen, died (May 17) in Göttingen. He was the son of a merchant. Girtanner studied medicine at Göttingen, and after receiving his degree (1783), made a study-tour through Switzerland and France, and studied more chemistry in Edinburgh (where he became acquainted with Brown's system), returning to Göttingen, where he began a medical practice. He introduced Brownianismus into Germany as though it were his own, and then later accused Brown of plagiarism.

Girtanner was a friend of Kant's former student, J. B. Jachmann, and in one of Jachmann's letters to Kant (14 October 1790,#452; Ak. 11:218) we find a description of their travels through revolutionary France. Kant refers to Girtanner's book on natural history (1796) in his Anthropology (Ak. 7:320) and his Physical Geography (Ak. 9:314). [Sources: ADB]

Born (Oct 16) and died (Dec 12) in Bern.  Haller gained notoriety first as a poet, publishing a volume of poetry when he was 24 that saw eleven editions in his lifetime. In the life sciences he was an early proponent of the experimental method, and was famous for basing his claims on multiply-repeated observations. He published prolifically on anatomy, botany, embryology, and scientific bibliography, and was an early founder of modern physiology.

Haller built on Boerhaave’s view that fibers were the basic structural units of living bodies, and published an early work on tela cullulosa, or cell tissue (1748). Haller was the first to recognize the autonomous function of the heart, arguing against Stahl that its actions cannot be caused by the soul, since it continues to beat even when removed from the body. Haller explained this in terms of irritability: the heart has an inordinate amount of this property, and therefore is able, at least for a time, to stimulate itself into continued action. He also observed the effects of respiration on blood flow through the heart, and later provided the first proper description of the diaphragm (1744). On the basis of his numerous experiments, Haller demonstrated irritability as a property unique to muscle tissue (it was virtually identical to the contractability of muscle fibers), and sensibility as a property unique to nerves (see his 1752 treatise). Manipulating a nerve might cause no outward change to it, yet can cause an attached muscle to contract violently — it senses the stimulus, without responding to it.  This work, although flawed in many ways, formed the foundation of modern neurology.

Haller’s studies of gonads quickly led him into researching embryological development. The central controversy of his day was whether the individual resulted primarily from the egg (ovism) or the sperm (animalculism). Cutting across this debate was the question of whether a pre-formed individual already existed (in either the sperm or the egg) and merely had to grow (evolutionism or preformationism) or whether all the parts of the embryo had to be formed anew (epigeneticism). Partly due to his poor eyesight, and partly due to various difficulties with his preparation of chick embryos, Haller felt he had evidence for a preformed individual within the egg, which then needed merely the stimulation of the sperm to begin its growth. While he came down on the wrong side of this controversy, he did make some contributions of more lasting value. By a careful study of the rate of fetal growth, both of the body as a whole and of the various parts, he was able to demonstrate the early rapid growth and gradual tapering off. In the last years of his life, Haller prepared a massive bibliography of medical literature. [Sources: Baldinger 1773, 58-75; Börner 1749-53, i.172-214, 913-15, ii.429-33, 751-60, iii.382-85, 653-77; Jöcher/Adelung 1787, 2:1742-54; ADB; DSB; NDB]

Johann August Eberhard was born (Aug 31) in Halberstadt, and died (Jan 5-6) in Halle, where he had studied theology under J. S. Semler and S. J. Baumgarten, and later taught as a full professor of philosophy. He was the son of a cantor and teacher. 

Eberhard’s Allgemeinen Theorie des Denkens und Empfindens was awarded the prize of the Berlin Academy in 1776, and in 1778 assumed the chair of philosophy at Halle that had been vacated by G. F. Meier’s death, and it was here that he wrote several textbooks, including the Vorbereitung zur natürlichen Theologie (1781) that Kant used in his courses on rational theology. Eberhard later entered a dispute with Kant on the relationship between the critical philosophy and Leibnizian rationalism: see Kant’s “On a Discovery, according to which any new Critique of Pure Reason is made Superfluous through an Older” (1790)[writings]. With J. G. E. Maas, Eberhard published the Philosophisches Magazin (4 vols., 1788-92), an organ for Wolffian philosophy, and see Kant’s sketch of a review of Eberhard’s Magazine (Ak. 20:381-423). Eberhard's other texts were often used in Königsberg, for instance, Kant's friend Pörschke made constant use of his aesthetics text (1783) as well as his history of philosophy (1788).

Born (Feb 19) and died (Nov 12) in Halle. He was the son of Friedrich Hoffmann the Elder, the respected municipal physician of Halle, and followed in his father's footsteps, eventually winning for himself the titles "Aesculapius Hallensis" and "the second Hippocrates." He was among the most widely read medical authors of the eighteenth century, and is best known for his systematic discussion of the iatromechanincal model of medicine — similar to what Hermann Boerhaave (1668-1738) was developing at Leiden — that views the human body as a hydraulic machine wholly governed by mechanical laws. Hoffmann was was called in 1693 to serve as the first professor of medicine at the newly founded university at Halle, where he was an ally of the pietist A. H. Francke (1663-1727). Here he taught for nearly fifty years, and until 1716 alongside Georg Ernst Stahl (1660-1734), who held the second chair of medicine, and together they transformed Halle into the preeminent medical school among German-speaking universities. A longer biography of Hoffmann is also available.

Considerable correspondence with Kant, beginning in March 26, 1786. He wrote textbooks on logic and metaphysics with a Kantian slant — his logic text [Halle, 1788] is considered the first based on Kantian principles — and Kant wrote a preface to Jakob’s 1788 book on Mendelssohn. [writings] See also his three-volume translation with commentary of Hume’s Treatise of Human Nature (1790-92). J. G. K. Kiesewetter [bio], later a close associate of Kant’s, matriculated at Halle in 1780 to study theology and first learned of Kant’s philosophy in Jakob’s lectures. The Scotsman John Richardson stayed in Jakob’s house while preparing his translation of Kant’s Metaphysical Foundations of Natural Science. Jakob’s book on empirical psychology (1791) was used at Königsberg in the anthropology lectures given by K. L. Pörschke (beginning with WS 1797/98) and later by J. F. G. Lehmann (SS 1802). [Sources: ADB; Vorländer 1918, 6; Oberhausen/Pozzo 1999, 660 seq.]

1694: Prof. of Law (Halle).

Christian Thomasius was born (1 Jan 1655) in Leipzig, and died (23 Sep 1728) in Halle. He was an important early Enlightenment educator supporting religious toleration, common sense over scholastic subtleties, and strongly opposed superstition in general and the persecution of witches in particular.  Thomasius also served as a counter-point to Wolffian philosophy, and in this regard his followers would include Johann Budde, C. A. Crusius, A. F. Hoffmann, and Andreas Rüdiger.

Thomasius’ father was Jakob Thomasius, the rector of the Nicolaischule at Leipzig as well as a professor of philosophy at the university, and who had taught Leibniz (the elder Thomasius had succeeded Leibniz’s father at the university in 1652 as the professor of moral philosophy, next moving to the chair of dialectics in 1656, and finally in 1659 to rhetoric, which he held until his death in 1684; Leibniz attended the university there from 1661-66). After studying at Leipzig and Frankfurt/Oder, where he received his doctorate of law, Thomasius began lecturing at Leipzig, eventually receiving a professorship of law.  As a student, he had rejected Pufendorf’s grounding of natural law of divine revelation, but reading Pufendorf's Apologia (1674) amounted to a conversion experience for Thomasius, leading him away from his Orthodox upbringing and setting him onto the path that would come to be called “the German Enlightenment.” In 1688 he began publishing a German-language monthly — the first of its kind, according to Beck — that contained articles and book reviews, and was in general aimed against the scholasticism and religious intolerance — in short, the Lutheran orthodoxy — of his day. His unconventional views and behavior — he was tolerant of mixed marriages between Calvinists and Lutherans, he lectured in German, and he is said to have been the first professor to have worn a sword during his lectures — led to his censure in 1690, causing an escape to Berlin and eventual relocation at Halle to teach at the Ritterakademie, which in 1694 became a new university, with Thomasius being appointed as the 2nd chair in law. He became an eager convert to Pietism (under Francke’s influence), although this quickly cooled (perhaps also due to Francke). Beck quotes one of Thomasius’ criticisms of Francke’s educational practices at the pietist orphanage at Halle, noting that Francke was turning them into “monks, that is, uneducated, melancholy, fantastic, obstinate, recalcitrant, intolerant, and spiteful men.”

Thomasius began giving his lectures in German in 1687 — generally considered the first to do this among the German universities (or, according to Beck, the first to publicly announce that he would lecture in German). [Sources: ADB; Beck 1969, 247-56; Sassen, SEP]

1745: Given the title: Freiherr von Wolff.

Christian Wolff was born (24 Jan 1679) in Breslau, and died (9 Apr 1754) in Halle. Through his voluminous writings, in both German and Latin, Wolff developed a workable German philosophical vocabulary, he introduced a “spirit of exactness and rigor” into German philosophy (to quote Kant), and he was instrumental in developing a secularized scholasticism infused with the science of his day. The tremendous popularity of his writings made him a central figure for any 18th century German philosopher — either to emulate, to modify, or to challenge.

Wolff studied theology at the Magdalen Gymnasium in Breslau with the intention of entering the ministry, but also mathematics and philosophy, and although he was Lutheran, the many Jesuits in Breslau gave him considerable exposure to Catholic philosophy. He matriculated at Jena at the age of 20, and it was here that he became interested in applying the methods of mathematics to the problems of theology and philosophy, with the hope of settling conflicts in these disciplines. This led to his Habilitationsschrift (On Applying the General Mathematical Method to Practical Philosophy [De philosophia practica universalis mathematica methodo conscripta]), written at Jena but submitted to the faculty at Leipzig, where he had also received his Magister degree, and where he began offering lectures. This and another mathematical work was sent to Leibniz, beginning a correspondence between the two that lasted until Leibniz's death in 1716, although these letters primarily concern mathematics and the natural sciences. As Leibniz wrote to another correspondent: “Mr. Wolff has agreed with some of my sentiments, but since he is very busy with teaching, especially mathematics, and we have not had much communication concerning philosophy, he can hardly know more of my opinions than those which I have published.” [qtd. in Corr 1975, 248]

With the help of Leibniz, Wolff was appointed to the full professorship of mathematics in 1706 in Halle, lecturing on mathematics, natural science and, after 1709, metaphysics, logic, and ethics. Growing conflicts with the Pietists in Halle led to their insinuating to Friedrich Wilhelm I that Wolff's philosophy was a form of fatalism (with the implication that soldiers might abandon their post without punishment since desertion was beyond their control) — this led to a Royal decree (8 Nov 1723) that Wolff leave Prussia within forty-eight hours or be hanged. Wolff promptly left for Marburg, where he accepted a professorship that had been on offer from the previous summer, and lectured on pure and applied mathematics, experimental physics, and ethics; on logic and metaphysics between 1731-40, on politics between 1733-40, on Grotius from 1732-40. After Frderick the Great assumed control, Wolff was invited back to Halle on July 6, 1740 — after turning down an invitation to help direct the Academy of Sciences in Berlin.

As for his many publications, it can be briefly noted that he wrote a great many textbooks in German during his first tenure at Halle, and then revised and reissued much of this material in Latin form while at Marburg. Consequently, there is a doubling of much of his writing, and the German versions are often referred to as such (e.g., the “German Metaphysics” of 1719, which re-appeared in a revised and Latin form as a separate ontology, cosmology, psychology and natural theology, 1730-37).

Kant used Wolff’s popular mathematics text (Auszug, 1713), and of course the Baumgarten texts used in Kant’s metaphysics, natural theology, and ethics lectures (and to a lesser extent the anthropology lectures) were heavily Wolffian. Kant wrote: “Wolff did great things in philosophy; but he got ahead of himself and extended cognition without securing, altering, and reforming it through a special critique. His works are therefore very useful as a magazine for reason, but not as an architectonic for it. Perhaps it is in the order of nature, although certainly not to be approved of in Wolff, that at least the experiments of the understanding should first multiply without a correct method of knowledge, and be brought under rules only later.” [Refl. #5035, Ak. 18:68, dated 1776-78; transl. Guyer et al. (2005)] Hagelgans [1737] lists him as “Consil. Reg. & Prof. Philos. primar. Acad. Lond. Paris. Berol. & Petropol. Sodalis.” [Sources: ADB; Gundlach 1927, 370; Beck 1969, 256-75; Corr 1975] [last update: 21 April 2007]

Wilhelm Abraham Teller was born (9 Jan 1734) in Leipzig and died (9 Dec 1804) in Berlin. He was the son of Leipzig pastor and professor of theology Romanus Teller (d. 1750). Teller’s 1764 textbook on the Christian faith, published while he was a professor at Helmstedt, favored a deistic rationalism over the truths of special revelation, which won him few supporters among the local orthodoxy. He did better in Friedrich II’s Berlin, where Teller served on the Oberkonsistorium, the administrative council of the Lutheran church in Prussia, and he was a founding member of the Berlin Mittwochsgesellschaft, a small secretive group of Enlightenment thinkers that met each Wednesday, and that included many theologians and philosophers — Moses Mendelssohn being the best known. As did others in the group, he came into conflict with Woellner after Friedrich Wilhelm II ascended the throne in 1786 (September 19).

1768: Professor of Theology (Jena).

Ernst Jakob Danovius was born on 12 March 1741 in Redlau (near Danzig), and died 18 March 1782 in Jena, as a result of throwing himself into the river Saale — he had been lecturing against suicide, the occasion being Goethe’s Sorrows of Young Werther (1774), which Danovius viewed as an overly seductive defense of suicide. Danovius was a professor of theology who sought to introduce Enlightenment reforms, and was also one of Kant’s early supporters at Jena.

Danovius studied under the Wolffian Johan Ernst Schubert and the deist Wilhem August Teller [bio] while at Greifswald, and then under Johann David Michaelis [bio] at Göttingen. Other important influnces were the Leipzig theologian J. A. Ernesti [bio] and the Halle theologian J. S. Semler [bio]

Perhaps his closest colleague at Jena was the Kantian theologian Johann Wilhelm Schmid [bio]; along with Danovius’s brother-in-law, C. G. Schütz [bio], they formed an important circle of early Kant supporters at Jena. K. C. E. Schmid [bio], who later gave lectures at Jena on Kant’s Critique of Pure Reason, was taking classes with Danovius during his last years. With respect to Kant, see his letter of Jan. 12, 1770 [#49, Ak. 10:87-88], informing Kant of a new chair of philosophy at Jena, and inquiring as to Kant’s interest in accepting it [more]. A longer biography of Danovius is also available. [Sources: ADB]

Johann Gottlieb Fichte was born 19 May 1762 in Rammenau as the son of a village ribbon weaver, and died 27 Jan 1814 in Berlin,[1] having held the first chair in philosophy at the new university there, as well as serving as its first rector. He is generally considered the most significant of the German Idealists following Kant. Because biographical information on Fichte is readily available, a bare minimum will be given here, with any detail stemming from his connections with Kant and Königsberg.

Fichte attended the Fürstenschule at Pforta before matriculating at the university in Jena and then at Leipzig. He worked as a private tutor for nearly a decade. Fichte traveled to Königsberg in the summer of 1791, where he stayed from July to October, in order to meet Kant and to attend his lectures. Fichte's diary indicates that he also became acquainted with Theodore von Schön [bio][2], who was completing his third year at the university, since Fichte borrowed and copied excerpts from von Schön’s notes from Kant’s anthropology lectures [notes]. Through Kant he also became closely acquainted with the mathematics professor, Johann Schultz [bio], and his wife Johanna (née Büttner).[3]

During his time in Königsberg, and in order to impress Kant, he wrote (between July 13 and August 18, 1791) an Essay toward a Critique of All Revelation, which was published anonymously the following year. This work won critical acclaim, and many took Kant to be the author, since he was said to be working on a book on religion. Kant eventually issued a public notice (31 July 1792) [writings] identifying Fichte as the author, and this secured the latter’s fame. He replaced Reinhold [bio] at Jena (at Goethe’s insistence), but was dismissed in 1799 because of conflict with student societies.

There is evidence of seventeen letters between Kant and Fichte (four from Kant) that followed his visit to Königsberg in 1791, and ended with Kant’s public distancing (28 August 1799) from Fichte’s writings. [writings] [Sources: Hartung 1825, 263; ADB; Manthey 2005, 331-36; v.Schön 2006, 69] [last update: 11 Sep 2012]

[1] According to the ADB. Brezeale’s article on Fichte in the Stanford Encyclopedia of Philosophy claims January 29.

[2] In his autobiography, von Schön [2006, 67] notes that when Fichte first came to town he ate lunch at the same inn as von Schön, which was frequented by military personnel, bureaucrats, shopkeepers, students, and travellers. Fichte ate silently at the common table until one day someone tried to justify a comment of theirs by appealing to Kant, whereupon Fichte said: “Apparently he hasn’t read Kant!” and after that time Fichte took regular part in the table conversations.

[3] Fichte might well have stayed longer in Königsberg, but for this relationship with Hofprediger Schultz and his wife. As von Schön explains in his autobiography:

“Fichte wanted to accept a Hauslehrer position, and was anxious to get this as soon as possible because of a situation that came up unexpectedly. Namely, Kant had introduced him to a family where he found interesting, philosophical conversation, but where at the same time the woman of the house developed such a burning affection towards him, and which he couldn’t return due to her being married, that he wanted to escape from Königsberg as soon as possible”

Fichte wollte eine Hauslehrerstelle annehmen und war eines unvermuthet eingetretenen ereignisses wegen eifrig bemüht, diese so bald als möglich zu erhalten. Durch Kant war er nämlich in einer Familie bekannt gewoden, wo er interessante, philosophische Unterhaltung fand, wo aber zugleich bei der Frau des Hauses eine so brennende Zuneigung gegen ihn sich inteickelte, daß er, der diese Neigung nicht erwidern konnte, des ehelichen Glücks wegen, so bald as möglich Königsberg verlassen wollte.

1810: Prof. of Medicine (Berlin).

1815: Hufeland remarries (Helene Troschel (1777-1862), the daughter of the head pastor of the Berliner Petrikirche).

Christoph Wilhelm Friedrich Hufeland was born 12 August 1762 in Langensalza into a medical family, both his father and grandfather having served as personal physician at the Weimar court. His father, Johann Friedrich Hufeland (1730-87), was called to Weimar when Christoph was only three, and so he was raised in a culturally rich environment, inspired by Herder’s sermons and, as an adult, attending Goethe’s weekly “Friday Society” gatherings. His childhood playmates included the future playwright August von Kotzebue (1761-1819). After studies at Jena and Göttingen, Hufeland kept a private practice in Weimar for ten years (1783-93) before beginning a long teaching career at Jena (1793-1801) and Berlin (1801-36). He was especially well known for his popular writings on health and child rearing. Despite a deepening blindness in old age, Hufeland remained active to the end, sending his Enchiridion medicum (1836) to the printer just days before his death at the age of seventy-four on 25 August 1836.

Hufeland sent Kant a copy of his Macrobiotics: Or the art of prolonging human life (Jena, 1797) — see Kant’s letter acknowledging receipt and thanking him (#740, March 1797). [see also: Kant’s letter to him of April 19, 1797 (#746); as well as Ak. 12: 136, #728; Kant’s letter of Feb. 6, 1798 (#796); Kant’s letter to Nicolovius of May 9, 1798 (#772). But see especially Kant’s open letter to Hufeland that forms the third part of his Conflict of the Faculties (Ak. 7: 97-116). He has been confused in the Kant literature with his cousin, Gottlieb Hufeland (below), who was a professor of law in Jena and co-director of the Allgemeine Literatur-Zeitung, and with whom Kant also had dealings. A longer biography of Hufeland is also available. [Sources: ADB; DBE; NDB]

Johann Wilhelm Schmid [also: Schmidt] was born (29 Aug 1744) and died (1 Apr 1798) in Jena; his father was the lawer Paul Wilhelm Schmid, later a professor in the faculty of law and a court counselor for Saxon-Coburg. He was an early Kantian theologian who sought to harmonize Kant’s practical philosophy with Christianity.

Schmid attended the gymnasium at Jena before beginning studies at the university at age 14, studying theology under J. G. Walch and J. C. Köcher. As a professor of theology at Jena, he was close friends with E. J. Danovius [bio]. Schmid viewed reason to be the source of morality, with special revelation being merely a means for its more rapid spread. It appears that a daughter of his married the Kantian K. C. E. Schmid (see below), who also edited the third volume of his Christian Morality (1804). [Sources: ADB] [last update: 4 May 2007]

Karl Christian Erhard Schmid was born (14 Apr 1761) in Heilsberg (near Weimar) and died (10 Apr 1812) in Jena; he was the son of a pastor. Schmid is best known for his early support of Kant’s critical philosophy, and for his widely-used dictionary of Kantian terms (1786).

Schmid was the Hofmeister for Friedrich von Hardenberg (Novalis); and while in Jena married Friedrich Schiller and Charlotte von Lengefeld (22 February 1790). He was called to a professorship in Giessen beginning WS 1791/92, but returned to Jena in the summer of 1793. He wrote a commentary on Kant’s Critik der reinen Vernunft (1786) while lecturing on Kant during WS 1785/86, publishing the book piecemeal during the semester. He sent a copy to Kant on 18 May 1786, once it was fully published (Professor Bering of Marburg also lectured from this book). He also published a Kantian textbook on moral philosophy (1790). A work on physiology (1798) was well-received in the medical community. See L.

Christian Gottfried Schütz was born (19 May 1747), the son of the local pastor, in Dederstädt (Mansfeld), and died (7 May 1832). He was a philologist and co-founder and editor of the Allgemeine Literatur-Zeitung (1785-1804).

Christian Gottfried Schütz attended Francke’s orphanage school in Halle, then studied theology, philosophy, history, and ancient languages at the university, where he was mentored by J. S. Semler [bio]. During his early years at Halle he was especially engaged in pedagogical matters, and briefly ran a small instutute that gave students hands-on experience at teaching, and was developing textbooks for use in the grade schools (for instance, a Kinderlogik).

His house in Jena, where he taught for twenty-five years, was an important meeting place for local intellectuals, attracting such guests as Schiller, Goethe, Wilhelm v. Humboldt, Reinhold, and Fichte. He founded at this time, with Gottlieb Hufeland, the Allgemeine Literatur-Zeitung in 1785, a four page daily newspaper (sometimes with double issues on a day — each four pages, and with its own issue number) featuring book reviews and other brief items; Kant’s review of Herder appeared in the first week (#4, January 6). This quickly became one of the most widely read journals for book reviews.[1] When Schütz returned to Halle in the spring of 1804, he took the journal with him. There is extensive correspondence between Kant and Schütz. [Sources: ADB; Hinske] [last update: 12 May 2007]

[1] At least according to Schütz’s own claims, who wrote in a letter to Kant (23 June 1788; #330, Ak. 10:540-3) that more than 2000 copies of each issue are printed, with an estimated 40,000 readers — “a single copy is read not by 10 or 20 people, but 30, 40, 50.” Cf. Vorländer [1924, i.408].

Ulrich, Johann August Heinrich (1746-1813)

A Wolffian Professor of Ethics and Politics at Jena, and an early supporter of Kant's new critical philosophy (“The Critique contains the true and only code of genuine philosophy” — as qtd. in Reinhold’s letter to Kant [#320, 1 March 1788] — this was Ulrich’s position before Reinhold’s arrival in Jena); but after Reinhold's quick rise as a Kant-popularizer, Ulrich soon turned to critic (“Kant, I wll be the thorn in your side, I will be your pestilence.” — again qtd. in a letter from Reinhold [#318, Ak. 10:523]. He was the first at Jena to lecture on Kant, offering a course on logic in WS 1784/85 using his new textbook (1785), and “in particular with reference to the whole of the Kantian doctrine” (qtd. in Hinske et al. 1995, 6).

Ulrich wrote a Wolffian metaphysics textbook with a Kantian slant (Institutiones, 1785), and had hoped Kant would review it for the Allgemeinen Literatur-Zeitung (21 April 1785; #239, Ak. 10:402); Kant’s colleague Johann Schultz [bio] ended up writing the review instead (ALZ, 13 December 1785). In this work, Ulrich tried to reconcile Kant and Leibniz and argued that the Critique should not limit knowledge to objects of possible experience, as well as questioning whether the table of categories was exhaustive. Schultz's sympathetic response to Ulrich (to certain of his doctrinal claims, but also noting that the transcendental deduction, which Schultz views as the heart of the Critical project, is far too obscure) helped motivate Kant to re-write the deduction for his 2nd edition of the Critique (on this, see also Kant’s long note to the preface of the Metaphysical Foundations of Natural Science [Ak. 4:474-76]).

Ulrich’s Eleutheriologie (1788) argues for a Wolffian compatibilism, holding that human freedom is compatible with the thoroughgoing causal determinism of the physical world because we are still able to act according to our choices, and that our choices can themselves be freely chosen in pursuit of moral ends; this work was briefly mentioned by Kant in the Vigilantius 4 moral philosophy notes [Ak. 27:479] as well as reviewed by Kraus (at Kant’s bidding and with his input in the Allgemeinen Literaturzeitung (25 April 1788; reprinted at Ak. 8:453-60). The heart of the Kraus/Kant reply was that Ulrich’s compatibilism failed to allow for the kind of freedom by which one “could have done otherwise” — the only sort of freedom that is morally relevant.

Born in a small village near Danzig (27 Nov 1754), died in his home in Paris (10 Jan 1794), Forster was an acclaimed naturalist, writer, and world traveler. His father was Johann Reinhold Forster (Halle; see); together they accompanied Cook on his second voyage around the world (1772-75). He was a professor of natural science at the Carolinum in Kassel (1778-84), than in Vilnius (1784-88), during which time he travelled to Halle (1785) and submitted a work on the plants of the South Pacific for a doctorate in medicine. His friend Johannes von Müller, the university librarian in Mainz, managed to have Forster replace him in 1788. In 1792 Mainz came under control of the French revolutionary army, and Forster was sent to Paris to negotiate Mainz becoming a part of the French Republic, a plan that ended with Mainz falling to the Prussian and Austrian armies, making Forster an outlaw unable to return. He eventually died of an illness in his Paris apartment.

Forster had criticized Kant’s “Concept of Race” (1785)[writings] and “Conjectural Beginning” (1786)[writings] in two essays published in the Teutschen Merkur (October and November, 1786, pp. 57-86, 150-66), to which Kant responded with his “Teleological Principles” (1788)[writings].

Herder, Goethe, and Kant (who wrote an afterward for Soemmering's Organ of the Soul, 1796). A longer biography of Soemmerring is also available. [Sources: ADB; DBE; DSB]

Born in 1734 in the village of Piasecznik (German: Petznick, in what was then Pomerania, now part of Poland), the son of the local pastor; he died on November 12, 1807, in Kiel. 

Hermes studied first in Wernigrode, then matriculated in theology at the university at Halle. After teaching and pastoring in Berlin and then Breslau, and serving in various ecclesiastical offices, he was called to Berlin by the Minister of Education and Religious Affairs, J. S. Wöllner, to be a member of the Royal Religious Examination Commission, working alongside fellow Rosicrucian G. F. Hilmer. As censors, they were responsible for rejecting (in 1792) the second part of Kant’s Religion, and thus delaying its publication by a year. Hermes was likely responsible for getting his boss (Wöllner) demoted by the king for moving too slowly against the forces of Enlightenment (see the cabinet order of 8 March 1794). Not long after this Hermes and Hilmer began a tour of the universities in search of any unorthodoxies among the theology faculties. Their first stop was Halle, where students promptly took to the streets, laid siege to the inn where they were staying, and threw rocks through their bedroom windows. This experience sent them packing back to Berlin, cutting short their inspection tour. This commission was disbanded in 1798 by King Friedrich Wilhelm III, and both Hermes and Hilmer were let go.

H. D. Hermes is not to be confused with his younger brother, the novelist Johann Timotheus Hermes (1738-1821), author of Sophiens Reise von Memel nach Sachsen (1770-72), and who attended Kant’s lectures in Königsberg (matriculating 1 June 1757 — thus overlapping with T. G. Hippel’s [bio] time at the university). [Sources: Doering 1830, 121-23; Vorländer 1924, ii.141-48; Epstein 1766, 363-68; Wood 1996, 43-44] [last update: 23 Nov 2011]

Karl Leonhard Reinhold was born (26 October 1757) in Vienna, and died (12 April 1823)[1] in Jena. He was one of the first popularizers of Kant’s philosophy. 

Reinhold studed at a local Gymnasium in Vienna, then entered a Jesuit college in 1772 as a novice, which ended the following year with the abolition of the order. In the fall of 1774 he resumed his studies at a Barnabite college, and began teaching there in 1778. He was ordained as a priest in 1780, but left the order, and Austria, in 1783, for Leipzig. An encounter with Petzold encouraged him to matriculate at the university, where he studied for one semester, hearing Platner’s [bio] lectures, and the following year moved to Weimar, where he met and married (18 May 1785) Sophie Katharina Susanna Wieland, the daughter of C. M. Wieland [bio], the editor of the Teutsche Merkur. Reinhold began writing for the journal at this time, including a positive review of Herder’s Ideas on a Philosophy of History.

A reading of Kant’s Critique of Pure Reason led him to write his “Letters on the Kantian Philosophy” (installments in the Teutsche Merkur, beginning in August 1786), which popularized and strongly endorsed Kant’s new philosophical project. It was on the strength of these “Letters” that Reinhold was offered a full professorship at Jena, which he assumed in 1787, and his lectures on the Kantian philosophy were so well-received that what became a new generation of philosophers were soon drawn to study and teach at Jena, soon making it the center of German philosophy.

Reinhold and Kant never met, but Kant was always appreciative of Reinhold’s help, and their correspondence is extensive (Reinhold introduces himself to Kant in a letter of 12 October 1787 [#305, Ak. 10:497-500]). By 1790 Reinhold was re-considering his Kantian commitments, and by the end of the 1790s his philosophical views were more closely aligned with Fichte’s Wissenschaftslehre. [Sources: ADB] [last update: 9 Oct 2013]

S. Beck’s letter to Kant (Aug. 1, 1789): “Prof. Caesar should be valued for his good-natured character. He really is making an effort to understand your system. Only I don’t know what I should make of the strange sort of doubts that he has regarding it, for example, he finds light and unity in the Deduction of the Categories, but darkness in the [discussion] of quantity and quality, even contradictions with respect to relation and modality.” [Sources: ADB]

Born 10 Jun 1715 in Leuna (by Merseburg), died 18 Oct 1775 in Leipzig.  He was the son of a pastor. Studied philosophy and theology in Leipzig under the pietists Andreas Rudiger and Rudiger’s pupil Adolf Friedrich Hoffmann, whose views Crusius systematically developed. He became a prominent critic of Leibnizian and Wolffian philosophy (especially their use of the principle of sufficient reason), and his textbooks were taught widely at Königsberg (resulting in a censorship of those professors in 1775).

The early Kant was actively engaged with Crusius’s philosophy. Kant’s habilitation thesis (New Elucidation of the First Principles of Metaphysical Cognition, 1755; Ak. 1:387-416)[writings] takes aim at Crusius, as does the entire fifth section of Kant’s Observations on the Feeling of the Beautiful and the Sublime (1764; Ak. 2:207-56)[writings].

Also: Gottscheed. Born in Juditten (2 Feb 1700) by Königsberg (not to be confused with Judtschen, where Kant first tutored), died (12 Dec 1766) in Leipzig; he was the son of a pastor. He studied in Königsberg, learning Wolffian metaphysics from Georg Heinrich Rast [bio] and poetry from J. V. Pietsch [bio], and taught there briefly before leaving for Leipzig in 1724.[1] Gottsched opposed Leibniz’s monadology in a dissertation (1722). His Foundations of all Philosophy (1733-34) became a standard Wolffian textbook, and was more enjoyable to read than Wolff’s own texts.

Gottsched was an mportant reformer of German theater and aesthetic theory. In 1745 he founded the journal Neue Büchersaal der schönen Wissenschaften und freien Künste. A literary society in Leipzig that Gottsched took over, reorganized, and renamed as the “Deutsche Gesellschaft” was later attended by J. J. Quandt [bio] and C. C. Flottwell [bio] after which Flottwell created a sister society in Königsberg on Nov. 15, 1741, called the “Königlich Deutsche Gesellschaft.” [Sources: Hagelgans 1737; Arnoldt 1746, ii.433; Pisanski 1886, 536; APB; ADB; Beck 1769, 279-81] [last update: 7 Mar 2013]

Born (Dec 17) in Hofgeismar, died (Jun 3) in Marburg. He studied philosophy at Marburg under Coing, after which he worked as a private tutor until 1779, when he returned to the university to teach, lecturing on the history of philosophy, ethics, psychology, and natural law. He served as dean of the philosophy faculty for 1786, 1795, 1804, 1817, and prorector of the university for 1789.

Bering subscribed to Kant’s Critical Philosophy, although he admitted in a letter to Kant that he didn't understand everything in the Critique and the Prolegomena. His dissertatio pro loco (upon taking the chair of logic and metaphysics in 1785) was in large measure directed against Dietrich Tiedemann’s criticisms of Kant (Tiedemann was teaching at Kassel, but would move to Marburg the following year).

Bering’s first letter to Kant (5 March 1785; #238) asked for a copy of Kant’s metaphysics notes from which he lectured. Kant, of course, lectured not from his own notes, but from Baumgarten’s Metaphysica, and it turned out that Bering was also lecturing from this text (although from Meier’s German translation). A second letter of September 24 accompanied a copy of his dissertation. Kant responded on 7 April 1786 (after his last metaphysics lecture of the winter semester), acknowledging Bering’s good work and suggesting that Tiedemann’s criticisms of his work missed the mark rather badly for lack of proper understanding. In a letter of 21 September 1786, Bering informed Kant of the prohibition to teach Kant’s philosophy at Marburg. This prohibition was especially disconcerting to the young Bering, since he was the only professor there engaged in such activity. A letter to Kant dated 28 May 1787 shows Bering avoiding the prohibition by “lecturing on your Critique to three hopeful boys under the rubric of a Konversatorii.” The ban was lifted in October 1787, a year after a letter signed by eight professors (including Bering) supporting academic freedom in general, and Kant’s philosophy somewhat. For a fuller account of this incident, see Stark [1996].[1] See also J. B. Jachmann’s letter to Kant (14 October 1790) with news of his visit with Bering. [Sources: Gundlach 1927, 285; Stark 1996] [last update: 10 May 2007]

De regressu successivo (Marburg 1785).

“About three weeks ago we received a Cabinet-Order here by which we were prohibited from holding lectures on any Kantian textbooks this winter, and that the philosophy faculty is required to report within 1/4 year what there is of value in Kant’s writings, and whether such gives rise to skepticism ....”

The cabinet order and the response by the Marburg philosophy faculty is reprinted at Ak. 13:182-5. Malter claims that the writings Bering sent were unread by Kant, who had Krauß pass them on to Hamann [Briefwechsel, 846]. Bering’s letter of 28 May 1787 reads in part:

“The prohibition to hold lectures on your writings has not yet been lifted. I have nonetheless violated it in the meantime, and am lecturing on your Critique with three hopeful boys under the title of a conversatorii” (Ak. 10:487-8).]

1779: Professor of History (Ritterakademie/Liegnitz).

1788: Professor of History (Elisabethanum/Breslau).

Johann Gottlieb Schummel was born (8 May 1748) in Seitendorf (near Hirschberg) and died (23 December 1813). He was notable both as an author and as a Gymnasium professor; and he exchanged a few letters with Kant. 

Schummel began studies as an eleven-year-old at the Gymnasium in Hirschberg, under which he suffered four years before escaping with a visiting troupe of actors that was passing through town (he was eventually retrieved by his father and returned to school). At the age of nineteen he abandoned the Gymnasium again, this time in the more usual fashion, and matriculated at the university in Halle, where he began an intense study of Wolffian philosophy. He also began to explore his growing literary interests, and during a year as a Hofmeister following his studies at Halle, he published a novel and a travelogue imitative of Sterne, although to terrible reviews. His teaching skills were rather more appreciated, and Schummel counted the years of his first teaching post in Magdeburg as among his happiest; one notable student from this time was the rather more successful author, J. C. F. Schulz. An interest in marriage led him to seek a better paying position, and he eventually was given the professorship of history at the academy in Liegnitz, where he taught for nine years. During this time he wrote to Kant (21 March 1783), expressing hope in eventually procuring a university position, as well as describing the death of his four-year-old son.[1] His last move was to the Elisabeth Gymnasium in Breslau, where he taught for twenty-five years, alongside his friend and colleague Christian Garve, and where he certaintly would have been made rector, but for his overly-public support of the French Revolution. [Sources: ADB] [last update: 25 Apr 2007]

[1] Schummel also wrote: “Your university is enjoying a considerable growth of students out of Schlesia. Would that they also come to you well prepared! But the constitution of our schools is not at all suited for that. At our Ritter-Academy in particular we receive students who are for the most part unformed, or even ill-formed blockheads. For that reason the King recently had a rather sharp memo sent round to the Schlesian nobility. That will likely only add to my misfortune, since despite my every effort, I cannot bring forth the quantity of good that I might be able to effect in some other situation” (#189; Ak. 10:305). [“Ihre Universität erhält diesmal einen ansehnlichen Zuwachs aus Schlesien. Möchten sie auch nur recht zubereitet zu Ihnen kommen: Allein die Beschaffenheit unsrer Schulen ist noch ganz und gar nicht darnach! Wir vollends an unsrer Ritter-Academie bekommen mehrentheils lauter ungeformte, oder wohl gar mißgeformte Blöcke! Deßhalb hat auch der König kürzlich an den schlesischen Adel ein scharfes Circulare ergehen laßen will. Auch das würd ich zu meinem Unglück rechnen, daß ich bei aller Anstrengung, bei allem Regen und Streben nicht die Sume des Guten hervorbringen kan, die ich mir in einer andern Lage zu bewirken getraute.”] On March 28, 1789, he wrote a second letter to Kant, this time on behalf of a student (#350; Ak. 11:13).

Beseke, Johann Melchior Gottlieb (1746-1802)

1766: Matriculation (Frankfurt/Oder).

1771: Private tutor (Halle).

1772: Magister, and Doctor of Law (Halle).

1774: Professor (Mitau).

Born (Sep 26) in Burg (near Madgeburg), died (Oct 8; 10/19, Gregorian calendar) in Mitau (now Jelgava, Latvia), a town lying forty kilometers south-west of Riga, and at the time the capital of Courland. He was the son of Christian Wilhelm Beseke, a well-known cleric serving as the inspector of the Jerichau Kreis. Beseke matriculated in 1766 at the university at Frankfurt/Oder to study theology, then changed to philosophy and law. He was also working as a private tutor to a young nobleman, and in this capacity accompanied his charge to Halle in 1771, where in 1772 he received both a magister (7 October) and a doctorate in law, and began lecturing in both philosophy and law. In 1774 he accepted a position at Mitau, where the city school was being transformed into the Academia Petrina. Beseke served as its first rector in 1775. (Immanuel Kant had already declined an invitation to fill this position, although his younger brother, Johann Heinrich (1735-1800), accepted and served as assistant rector from 1775-81 before moving on to a pastoral position.) Beseke's reputation grew to the point that he was offered (but turned down) the professorship of natural history at Rostock in 1790. He became a member of the Royal Society of Scholars at Frankfurt/Oder, as well as of the Latin society at Jena.

Beseke wrote popularizations and texts for secondary school students on the subjects of morality, law, logic, natural history, and natural theology. He sent a copy of his three volume Book of Wisdom and Virtue (1782) to Kant. In later years he wrote on the conditions of the poor.

C. F. Schulz’s (see) early death, and his letter (12 September 1799) thanking Kant, Kraus, and Schulz for their testimonials, having received the job.

Hartmann, Gottlob David (1752-1775)

Procured a professorship of philosophy in Mitau, and on his way there stopped in Königsberg to visit Kant. See his letter to Kant (Sept. 4, 1774): “I regret that I couldn’t stay longer in Königsberg and enjoy your company.... Your Critique of Pure Reason, of which you told me so much, has since occupied my thoughts long and often. Once you have finished this work, philosophy will have, I think, an entirely different shape.” [Sources: ADB]
