[Index of Königsberg Professors]

Ammon, Christian Friedrich (1696-1742)

1720 (Jun 22): Magister (Jena).

1721 (May 23): AR, Lecturer in Mathematics.

Christian Friedrich Ammon was born (10 Mar 1696) and died (1 Dec 1742) in Königsberg, where he was one of Kant's mathematics professors. Ammon began his own university studies at Königsberg, primarily under the mathematicians Christoph Langhansen [bio] and David Blaesing [bio] — the former a very young Pietist lecturer, the latter an Aristotelian. Ammon received his Magister degree at Jena (22 June 1720), returned to Königsberg the following year (7 June 1721), habilitated at the university on September 24 (with the dissertation De duobus theorematibus philosophicis una cum corollariis) and began lecturing on mathematics and philosophy the following year. He began his teaching career as an Aristotelian, but was using Christian Wolff’s textbooks by the late 1720s when Martin Knutzen [bio] was a student. Pisanski characterizes Ammon’s own textbook (1737) as a mix of Aristotle and Wolff. Ludovici claims that Ammon was widely known as a Pietist, and relates a story of how he anonymously dictated a series of Wolffian additions to a student’s response to a disputation presented by the medical professor M. E. Boretius [bio] on 18 May 1724, which led to the published disputation being banned. Immanuel Kant attended Ammon’s lectures in the early 1740s, and understood them well enough to be able to tutor his friends, as well. Kant’s former student and later colleague, C. J. Kraus, also mentions Ammon as one of Kant’s professors, but notes that he “must have been a real amateur, judging from a mathematical writing of his that I’ve seen” [Reicke 1860, 7].

A. Schultz and an invaluable local historian. An early interest and ability in poetry led to his first publication (1732), a study on the proper rules for writing poetry, laid out in Wolff's mathematical style. Arnoldt continued this interest throughout his life, and was president of the Royal German Society of Königsberg when he died. He also mentored the future novelist J. T. Hermes during the latter's studies at Königsberg (1758-61). A longer biography of Arnoldt is also available.

1733: Full Prof. of Poetry (Königsberg).*

Johann Georg Bock was born on 12 May 1698 and died 7 July 1762 in Königsberg. He was the oldest son of the city surgeon and brother to Friederich Samuel Bock [bio]; both brothers taught at the university at Königsberg alongside Kant, the older brother while Kant was still a student. 

Bock matriculated at the university on 1 September 1714, worked for several years as a private tutor, and then finished his studies in 1727 at Halle where he received the magister degree. He returned to Königsberg the following year (re-matriculating on 14 October 1728), although it appears he was not holding lectures, and was perhaps instead working as a private tutor. He was appointed associate professor of logic and metaphysics (to replace Salthenius) beginning in the fall of 1732, but was then made full professor of poetry the following year, succeeding Johann Valentin Pietsch [bio], whose poems he later edited. Bock’s habilitation (pro receptione) and inaugural (pro loco) disputations both occured in November 1733 and were published together; these concern poetic theory and develop a concept of a poem’s beauty based not on mere imitation, but rather on how lively it represents its object. Bock’s friend and correspondent in Leipzig, the Wolffian literary critic J. C. Gottsched [bio] — they had likely attended Pietsch’s poetry lectures together — was provoked by this into publishing a critical response.

Bock was a respected and successful poet of occasional and religious verse, a small selection of which was published in 1756, and he opposed the Pietism [glossary] sweeping through the university, complaining how it suppressed the arts; but he is best remembered for his dictionary of Prussian idioms and colloquialisms. Bock was inducted into the Berlin Academy of Sciences in 1732 and made an honorary professor of the St. Petersburg Academy in 1758. He features heavily in an historical novel by Olfers-Batocki [1986]. A biography of Bock by his colleague J. G. Pisanski (Königsberg, 1762) appears to be no longer extant.

Matthias Ernst Boretius was born (18 May 1694) in Lötzen and died (4 Oct 1738)[1] in Königsberg. He was the son of a pastor. He began his studies at the university in theology, then switched to medicine. After transferring to Leyden and studying under Boerhaave, he receiving his medical degree and traveled to England, where he witnessed the first experiments (on six condemned prisoners) of the new smallpox vaccine (20 Aug. 1721). Boretius brought the vaccine back to Prussia and published an account of this (1722). Pisanski [1886, 619] quotes a comment in a Hamburg paper of 1738 (likely an obituary): “With his frequent trips to Amsterdam, he became acquainted with the world famous anatomist Ruysschio [Frederik Ruysch], who loved him like a son, and entrusted him with many arcana anatomica.” Boretius had also prepared many anatomical specimens.

Born (Nov 12) and died (Aug 14) in Königsberg. He was the son of a Prussian bureaucrat, and taught mathematics and philosophy at the university in Königsberg as a colleague and rival of his more famous townsman Immanuel Kant. Both were talented lecturers, and lecturing over the same subjects, and therefore competing for the same students. Buck appears to have been a favorite of Knutzen over Kant. At least from Kant’s side, the hostility is palpable: in 1770, Kant maneuvered Buck out of his chair of logic and metaphysics and into an open chair of mathematics, so that Kant could take the logic/metaphysics chair,[1] and then in 1786, three days before Buck has even died, we find Kant promoting his colleague Johann Schultz for the position. A longer biography of Buck is also available. [Sources: Arnoldt 1756; Arnoldt 1769; Goldbeck 1782; Goldbeck 1781-83; Pisanski 1886; Metzger 1804; APB; ADB; Vorländer 1924; Gause 1996; Oberhausen/Pozzo 1999; Stark 1999b; Kuehn 2001]

Gotthilf Christoph Wilhelm Busolt was born (6 Feb 1771) in Buchholz (near Landsberg, in East Prussia) and died (3 May 1831) in Königsberg. His father was the local pastor in Buchholz, and Busolt entered the clergy as well, although he is best remembered for his work on Prussian school reform.

Busolt was educated at home, but at the age of eight he moved to Königsberg to live with relatives following his father’s death. He began university studies in Königsberg in the fall of 1788, where he attended lectures by C. J. Kraus and Immanuel Kant (there are three sets of notes associated with Busolt's name — on anthropology, on physical geography, and on logic — although it is likely that he only purchased and did not himself write them). He also began teaching at a local Gymnasium, the Altstadt School, where Daniel Weymann (a Pietist opponent of Kant’s) was the rector, and tutored in various homes. An early exposure to the writings of Pestalozzi (as well as those of Rousseau, Basedow, and Campe) shaped his interest in public educational reform and, after receiving his magister in 1798, he toured Germany to study different public schools. He returned to Königsberg in 1800 with a government appointment as church advisor, then later as school advisor, and in this capacity he attempted to introduce Pestalozzi’s teaching methods. Because of the Napoleonic wars, the royal family and various other Berlin luminaries, such as Wilhelm von Humboldt, resided in Königsberg in 1808-09, and the royal family (Friedrich Wilhelm II, Luise, and their children) spent the summers at Busolt’s estate just outside of town (the estate formerly owned by T. G. Hippel). Busolt gave public lectures on pedagogy at this time, which the royal couple, as well as Humboldt, attended.

Christoph Gottlieb Büttner was born (10 Jul 1708) in Brandenburg (now Ushakovo), about twenty kilometers south-west of Königsberg, and died (1 Apr 1776) in Konigsberg. He is best known as a skilled anatomist with a famous collection of prepared specimens, as well as for his work in forensic medicine and abnormal anatomy. (He should not be confused with either Christian Wilhelm Büttner (1716-1801), a professor of natural history at Göttingen, or Christoph Andreas Büttner (1706-74), a professor of philosophy at Halle.)

One minor biographical connection to his famous fellow townsman Immanuel Kant: Büttner married a daughter of Christoph Daniel Meltzer [bio], one of his old medical professors, and Büttner’s own daughter, Johanna Eleonora (1751-95), married the mathematician Johann Schultz [bio], a colleague and occasional collaborator of Kant’s. A letter from Johanna to Kant (22 December 1793) suggests a daughterly affection for the elderly philosopher. A longer biography of Büttner is also available.

Also: Ivan Parfenovich Chmelnitski. A Russian and a direct descendent of Hetman Bogdan Chmelnitski. He was born in January 1742, studied a year at Kiev Theological Academy, and then matriculated at the university at Königsberg in 1760, where Immanuel Kant had been lecturing since 1755. Only a few traces of his activity here remain. He received his magister from Königsberg in 1767 with a dissertation on de servitute minus toleranda, ob rationes, but he could not have lectured there long, if at all, and certainly not after 1769. He returned to Russia as First Secretary of the Senate, and was appointed by Catherine II to the commission on legal reform. He translated various scholarly works from the German into Russian, including a 'Refutatation of Slavery according to Natural Law' and the writings of the Czech educational reformer Jan Amos Comenius (1592-1670). He died on 2 January 1794.

In his remarks on the 1762 disputation on the 'elucidation of the principles of ontology' held by the Crusian Pietist Daniel Weymann (1732-95), Chmelnicki attempted to refute the basic metaphysical principles found in Baumeister's Institutiones metaphysica (1739) along the same lines as taken in Kant's Nova dilucidatio (1755). Baumeister's popular Wolffian metaphysics textbook had once been used by Kant in his lectures, and was still used routinely by the full professor of logic and metaphysics, Georg David Kypke (1724-79). At the beginning of the winter semester 1763-4, the newly habilitated Gottlieb Schlegel (1739-1810) published a disputation (De gravibus quibusdam psychologiae dogmatibus, 1763) which Chmelnicki criticized in a pamphlet later that year, arguing that Schlegel's topic hardly counted as gravia dogmata, that any claims proceeding from the simplicity of the soul are empty, and that his proofs for the soul's immortality all failed. Three years later (September 1765) the theology faculty prevented the publication of a further pamphlet of Chmelnicki's on the question of whether God must possess more than infinite power; the work appeared the following year.

A. Schultz and returned to Königsberg as an associate, then full professor of practical philosophy, lecturing primarily on natural law, using a text by L. P. Thümmig, Institutiones philosophiae Wolfianae (Frankfurt/Leipzig 1725-26), but also texts by Wolff and, later, Achenwall. Kant’s career was somewhat intertwined with Christiani’s. While jockeying for a full professorship, Kant once suggested to Berlin that Christiani assume the Mathematics position recently vacated by the death of his father-in-law (Langhansen).[1] Later, Kant entered the faculty senate upon Christiani’s death, and dedicated a poem to him.[2] Kant’s former student, Christian Jacob Kraus, replaced Christiani as full professor of practical philosophy.

[1] Kant had suggested in a letter to Carl Joseph Maximilian Freyherrn v. Fürst u. Kupferberg (March 16, 1770; Ak. 2: 90-91) that Christiani assume his father-in-law’s chair of mathematics, so that Kant could have the chair of practical philosophy. Kant noted that Christiani had as good an understanding of mathematics as anyone at the university, and that he was also the best candidate as inspector of the Alumnat [glossary], a position normally held by the mathematics chair because the astronomical observatory and related instruments were found there. This inspectorate also included the benefit of free lodging at the college.

He replaced Kant on the academic senate after Kant’s retirement in 1801, and was a regular table guest of Kant’s during the last three years. This led to his publishing a short biographical sketch (1804). Hasse represented Herder’s views on language and poetry in his lectures. Metzger notes his gifts as a philologist and classicist, as well as an exemplary teacher. [Sources: Metzger 1804, 66; Reicke 1860, 42; APB; NDB]

Born in Königsberg, the son of a shoemaker. He matriculated at the university in 1781 and soon became a student of Kant’s, as well as his amanuensis [glossary] from the spring of 1784 to 1788 when he left on travels through England, Scotland, and France. The clean copy of Kant's Grundlegung is in Jachmann's hand. He worked as a tutor for the wife of Pierre Jeremie Courtan, a merchant with the French colony in Königsberg, where J. G. Hamann made his acquaintance, and eventually Jachmann became good friends with Hamann's son, Michael.

During his travels, he would send descriptive letters back to Kant (from Edinburgh, 15 April 1789, #354, and 9 October 1789, #386; from Halle, 14 October 1790 (concerning his experiences in revolutionary France and Göttingen). While in Edinburgh he gave lectures on Kant’s philosophy. Kant wrote recommendations for him to visit Blumenbach and Kästner at Göttingen. He later practiced as a physician, married a daughter of Kanter’s, and offered occasional courses in the medical faculty at the Albertina: SS 1798 (physiology), WS 98/99 (venereal disease), and SS 99 (physiology). His younger brother, Reinhold Bernhard [bio], who became an important educational reformer in Prussia, also studied with Kant and served for a few years as his amanuensis.

1799 (Oct 11): Lecturer in Philosophy (Königsberg).*

1801 (July): Moves to Danzig.

1802 (Spring): Full Prof. of Philosophy (Dorpat).

(Also: Jähsche; first name is often wrongly listed as ‘Gottlieb’) Jäsche was born on 3 July 1762 in Wartenberg (near Breslau/Wroclow, in Silesia; now Poland) and died on 25 August 1842 in Dorpat (Tartu, Estonia). He is remembered primarily as an associate of Kant’s and the editor of Kant’s logic lectures [1800].

His father was a pastor and rector of the local school, and young Gottlob was tutored at home before entering the gymnasium in Breslau in 1777. He then studied theology at Halle (1783-85) under Nösselt [bio], Bahrdt [bio], and J. A. Eberhard [bio], then philosophy at Königsberg (Fall 1791, although his name does not appear in the Matrikel), attending Kant’s lectures on anthropology and metaphysics, as well as lectures by Kraus [bio] and Schmalz [bio]. Jäsche returned to Halle to receive his magister degree (1795), then returned to Königsberg where he habilitated (1799), and lectured for the next two years on metaphysics (using L. H. Jakob [bio], Grundriß der allg. Logik and C. C. Schmid [bio], Grundriß der Metaphysik), encyclopedia of philosophy (lecturing from his own notes), history of philosophy (using J. G. Gurlitt, Abriß der Geschichte der Philosophie), and logic (using Jakob, and then in SS 01 his own edited volume of Kant’s logic lectures).

Jäsche moved to Danzig in July 1801, bringing with him a large number of manuscripts given to him by Kant, and in the spring of 1802 assumed a professorship of philosophy at the newly founded universtiy at Dorpat (Tartu, Estonia). Much of this Kantiana was then passed on to Karl Morgenstern [bio], a younger colleague at Dorpat.

One point of unclarity in Jäsche’s chronology is the time he spent as a student at Königsberg. He arrived for the WS 91/92, and he attended Kant’s lectures on anthropology and metaphysics (and these are winter semester courses). It would have been odd for him not to have attended Kant’s logic lectures the following summer as well, but he doesn’t mention having ever attended them in his preface to Kant’s published logic lectures (and he almost certainly would have mentioned this, had he actually attended). All of this suggests that he might have studied in Königsberg just that one semester, rather than until 1794, when he returned to Halle. A biography with a more complete bibliography of Jäsche is also available.

Kanter, Johann Jakob (1738-1786)

Johann Jakob Kanter was born (1738) and died 18 April 18 1786 in Königsberg, where he was a publisher, bookseller, and Immanuel Kant’s landlord.

He was the son of Philipp Christoph Kanter (d. 1764), a printer and binder who opened a book shop at Langgasse 23 at the corner of Schmiedegasse (in the Altstadt). The elder Kanter was both a printer and a binder, and he made a small fortune printing Quandt’s [bio] bible and hymnal. When he died in 1764, the inheritance was divided among his four sons, all of whom remained in some aspect of the book business. The three older brothers were Daniel Christoph (d. 1812), who ran the family print shop (with seven presses, it was the largest in the city); Alexander, who poured metal-type; and Philipp Christoph Jr, who ran the bookbindery and the paper business. 

The youngest son, Johann Jacob Kanter (1738-1786), learned the book trade in Leipzig, returned to Königsberg in 1760, received a publishing privilege during the Russian Occupation [glossary] (later confirmed by Friederich the Great), and received a privilege to publish a newspaper so long as it brought no harm to Hartung’s business (who already had a newspaper publishing privilege) — for instance, he could print political news only after a certain period of time had elapsed. This seeming disadvantage actually made him his fortune, as his newspaper — the Königsbergsche Gelehrte und Politische Zeitungen — developed into an important literary organ in Germany, with correspondents in Curland, Poland, St. Petersburg, and throughout Germany, with reviews and articles written by such talents as Hamann, Kant, Hippel, Scheffner, and Herder.

After the great Königsberg fire of 11 November 1764, Kanter rented part of the newly-built Löbenicht Town Hall (on the corner of the Löbenichtsche Langgasse and Münchengasse, with a large square to the west) in 1766, where he installed a bookshop that soon became an important gathering place for the scholars of Königsberg. He rented lodging upstairs — Kant lived with him for eleven years (1766-1777) [more]. The bookshop fell on hard times toward the end of the 1770s, and Kanter gave it up in 1781. After Kanter’s death, the building was sold to G. L. Hartung.

Kanter had a good selection of books and he would loan them out (of which both Kant and Hamann were beneficiaries). Kanter pubished books (including seven by Kant) and his newspaper (in which Kant published six items), but his real interest was in retail. He also had a printing shop in Marienwerder, a filial in Elbing, and (purchased in 1775) a papermill in Trutenau (several sets of notes from Kant’s lectures were written on paper with the Trutenau watermark). Kant’s former student and amanuensis, Johannes Benjamin Jachmann [bio], married Kanter’s daughter.

Kanter is listed as offering a course in the philosophy faculty for WS 1770/71. [Sources: Krause 1881, 76-77; Gause 1996, ii.128, 233-37; Vorländer 1924, i.181; Oberhausen/Pozzo 1999] [last update: 4 Aug 2013]

Also: Knutz. Born (14 Dec 1713) and died (29 Jan 1751) in Königsberg, at the age of thirty-seven. He was the only son of Hagen Knudsen, a Danish merchant. Both his parents died by the time he was six, and he was raised thereafter by a great-aunt. Attended the Altstadt School; studied mainly mathematics and philosophy at the Albertina under Ammon, Teske, but also theology with F. A. Schulz, who converted him to Pietism [glossary]. Unlike so many, he received his magister degree at Königsberg (rather than Halle), and began lecturing in the winter of 1733 (pro receptione disputation: 11 Nov 1733, on the impossibility of the eternity of the world), and the following year was appointed associate professor of logic und metaphysics (pro loco disputation: 22 Apr 1735, on mind-body interaction).

Knutzen’s enlightenment tendencies moved him towards the Wolffian philosophy, but he remained at odds on various points (e.g., regarding mind-body interaction, he favored the causal influx theory over a pre-established harmony or occasionalism). Primarily because of Borowski’s comments, Knutzen has been viewed as the closest and most important of Kant’s teachers at the university (Kraus also claims that “the only teacher who could have stimulated Kant’s genius was Knutzen” [Reicke 1860, 7]); for a different perspective, see Kuehn [2001, 78-84].

Christian Jakob Kraus was born 27 Jul 1753 in Osterode (Kreis Mohrungen, East Prussia), and died 25 Aug 1807 in Königsberg. His father was a surgeon in Osterode, his mother the mayor’s daughter. His mother died just before he arrived at the university and he apparently received little emotional or financial support from his father.[2] Once in Königsberg he received support from his mother’s brother, Johann Christian Bucholtz, a pastor at the Altstadt church, who found him a place to stay. Unfortunately this uncle also died in 1773, forcing Kraus to support himself at the university by tutoring on the side. 

Kraus presumably matriculated as a theology student, but then in 1773 changed to the law faculty. He was an avid student of Kant’s (attending Kant’s lectures from 1771-74), but it wasn't until his third year at the university that he managed to make Kant’s acquaintance, after which Kant took an active interest in his success. [more] Kraus spent one year — April 1777 to April 1778 — serving as a Hofmeister to the eighteen-year-old Count Archibald Nicolaus Gebhard von Keyserling (a second cousin to Count Heinrich Christian Keyserling [bio], in whose palace in Königsberg he was living), and Kraus continued to live in the Keyserling household even after his Hofmeister duties were over.[3]

After his return to Königsberg as the Professor of Practical Philosophy (1781), Kraus became a regular at Kant’s table and a constant companion before their break in 1789 [Kuehn 2001, 331-34]. (In a letter to Marcus Herz, Kant described him as “one of my favorite and most capable students,” Oct. 20, 1778). While a student, he participated in various disputations, including the pro receptione for Johann Schultz (Aug. 2, 1775). Mendelssohn asked Kant, during his surprise visit to Königsberg (August 1777), whether Kraus (who was away at the time) would be interested in the professorship at Halle vacated by G. F. Meier’s death (Minister Zedlitz had asked Mendelssohn to propose someone)[Voigt 1819, 68-69]. [more]

Today he is best known as having been the first to introduce Adam Smith’s liberal economics into Germany (he devoted a set of lectures to the The Wealth of Nations in SS 1797, just after the German translation by Garve and Dörrien was published). His students included such future luminaries as President von Schön [bio], Minister von Schrötter, and Count Dohna-Wundlacken [bio]. [Sources: Metzger 1804, 65; Sembritzki 1907; Voigt 1819; Reusch 1848, 22-24; Krause 1881; APB; NDB; Stark 1987b; Röttgers 1995] [last update: 8 Aug 2013]

[1] Kraus’s early biographer Voigt [1819, 21] claims that Kraus entered the university in Königsberg in October 1770, but the matriculation records show him enrolling the following spring.

[2] Kraus's father died on 1 Nov 1777; in a letter to his brother dated 15 Nov 1777 Kraus discusses disposing of the estate [Krause 1881, 69-70].

[3] In a letter to his friend, von Auerswald, Kraus wrote (Saturday before Easter, 1777):

[...] I've been moved in with the Count Kaiserling since the 24th of April, where I've taken over the supervision of the son of the recently elevated Chamberlain Kaiserling, a youth of 18 1/2 years. [Voigt 1819, 61]

Seit dem 24sten April bin ich zum Grafen Kaiserling gezogen, wo ich über den Sohn des kürzlich in den Grafenstand erhobenen Kammerherrn Kaiserling,e inen Jüngling von 18 1/2 Jahren die Aussicht übernommen habe.

In a letter of 27 May 1778 to his brother, Johann Michael (two years older than Christian), Kraus wrote:

My young count has become a soldier, leaving me already a month ago. I continue to live with my old Count Keyserling, however, where I have free room and board, am waited on, and live like a child in the house. [...] I will stay here for as long as I'm in Königsberg, even if I establish myself and become a Master or a Professor, I am permitted to stay. [Krause 1881, 79]

Mein iunge Graf ist Soldat geworden und hat mich schon vorigen Monat verlassen. Ich bin indessen noch immerfort bey meinem alten Graf Keyserling im Hause wo ich freye Station, Aufwartung, freye Tafel habe und wie ein Kind im Hause lebe. [...] So lang ich in Königsberg bleibe, werde ich nimmer aus dem Keyserlingschen Haus kommen, und auch selbst wenn ich mich etablire und Magister oder Professor werde, dürfte ich da wohnen bleiben.

1779-84: 2nd Librarian, University Library (replaced C. D. Reusch).

Johann Gottlieb Kreutzfeld (also: Creutzfeld, Kreuzfeld), the son of a master tailor, was born 19 April 1745 in Königsberg, where he also died on 18 January 1784 of tuberculosis, not yet 39 years old. He taught poetry at the university in Königsberg alongside Immanuel Kant, having first attended his lectures at the university as a student (matriculating 28 September 1762, the same semester as J. G. Herder), then teaching at a local high school — the Altstadt Gymnasium — beginning October 1769. He was appointed full professor of poetry (replacing Lindner) in 1776, and began teaching with the 1777 summer semester; Kant quite likely had a hand in his being offered the position. Both Kraus [bio] and Wasianski [bio] served as student respondents at Kreutzfeld’s pro receptione disputation on Feb. 25, 1777, and Kant was among the disputants at his his pro loco disputation (25 February 1777) — his inaugural address for the Poetry chair; Kreutzfeld’s address as well as Kant’s response have been preserved [writings]

Kreutzfeld replaced C. D. Reusch as assistant librarian at the university library (in the castle) in 1779 — the same position held by Kant a decade earlier — and served in this capacity until his death. He was a friend of J. G. Hamann, wrote book reviews for the Königsberger gelehrter Zeitung, collected Lithuanian folk songs (or Dainos), and published poems in Voss's Musenalmanach, in Baczko's Preußische Tempe (Königsberg: J. J. Kanter, 1780-82), in the Preussischen Blumenlesen (Königsberg: Hartung, 1781-82), and in Gesängen für das schöne Geschlecht, a publication of his close friend J. F. Reichardt, who set several of these poems to music.

Georg David Kypke was born (23 Oct 1724)[1] in Neukirchen (Pomerania), and died (28 May 1779) in Königsberg. He was the son of a pastor, and nephew to Johann David Kypke (see below). Born the same year as Kant, they also both attended the Collegium Fridericianum in Königsberg, then at the university (there is record of Kypke publicly defending, under the physics professor Teske, an essay on the incomprehensibility of God’s infinite intellect on 2 July 1743).

Kypke also studied at Halle under Siegmund Jacob Baumgarten [bio], who instilled in him a strong interest in English. He was friends with J. S. Semler [bio], who was also studying under Baumgarten, and lived in the house of Kriegsrath Michaelis. After receiving his Magister at Halle, he returned to Könïgsberg, lectured for only two years before receiving an appointment as associate professor of Oriental languages (1746), and also offered courses on English. In 1755, the year when Kant returned to Königsberg as a lecturer, Kypke was promoted to full professor, and also published an abridged translation of Locke’s Of the Conduct of the Human Understanding (Hartung, 1755).[2] 

Kant lived with Kypke during these early years, although this relationship appears to have weakened with time, perhaps as Kypke became more involved with his garden, out of which he sold vegetables. Wannowski mentions Kypke as one of Kant's close friends during his early years teaching at the university, along with Funk, the professor of law [Reicke 1860, 39]. Schlegel also notes that Kypke used Baumeister’s textbook on logic and metaphysics — a text initially used by Kant, but eventually abandoned as too simplistic — for 30 years [1790, 223n]. A longer biography of Kypke is also available.

Also: Kipke. Born (Feb 8) in Neukirchen (Pomerania), died (Dec 10) in Königsberg. He was the son of a pastor. Attended the gymnasium in Stettin. In 1730 he married a sister of Professor Arnoldt. Kant applied for this chair at Kypke’s death, but the Academic Senate gave the post to Johann Friedrich Buck, who had served as a Lecturer longer than Kant.[1] He was rector four times, and in 1753 served as dean of both the philosophy and the theology faculties. A longer biography of Kypke is also available. [Sources: Hagelgans 1737; Arnoldt 1746, ii.190,192-3, 433; Arnoldt 1769, 17; Goldbeck 1782, 210; Bornhak 1900, 112; APB] [2]

[1] Six professors applied for Kypke’s position: Bock, Flottwell, Hahn, Kant, Thiesen, and Watson. Only Bock and Kant’s names were forwarded to St. Petersburg for final selection. Flottwell was a full prof. of rhetoric, Hahn a full prof. of oriental languages, and Gottfried Thiesen a full prof. of medicine (1730-75).

[2] The Academy edition mistakenly lists J. D. Kypke as the father of G. D. Kypke (instead of as his uncle).
