Reinhold Bernhard Jachmann (1767-1843)
[This is a draft of an article in The Dictionary of Eighteenth Century German Philosophers, 3 vols., edited by Manfred Kuehn and Heiner Klemme (London/New York: Continuum, 2010).]
Reinhold Bernhard Jachmann was born on 16 August 1767 in Königsberg and died while traveling on 28 September 1843 in Thorn (Torun, Poland), where he is also buried. He was the son of a shoemaker and younger brother to the physician Johann Benjamin Jachmann [bio], with whom he has occasionally been confused in the literature. Jachmann studied under Immanuel Kant and possibly served as his amanuensis [glossary] from 1788 until 1794, after which he left Königsberg to begin a successful career as pastor and educational reformer. Kant characterized Jachmann in 1800 as “formerly an industrious and alert auditor of my lectures, now a most treasured friend” (in his preface to Jachmann 1800 [writings]), and among Kant scholars he is remembered as one of Kant’s early biographers.
Jachmann attended the Altstadt Gymnasium in Königsberg, then matriculated at the university on 11 April 1783 as a law student, but studied philosophy and theology alongside his older brother, Johann Benjamin, who was pursuing a degree in medicine. Jachmann spent nearly eleven years in Königsberg as a student (by his own account, nine were spent in Kant’s classroom). This is a remarkably long time to stay at the university, although he was also working as a tutor during this time (for instance, with William Motherby, the son of Kant’s friend Robert Motherby). Kant took a personal interest in Jachmann, writing twice on his behalf to Hippel [bio], the relevant local authority (letters of 2 Sept 1787 and 6 Jan 1790). Jachmann also served as a respondent at K. L. Pörschke’s [bio] habilitation address (at which Pörschke became a Magister legens or private lecturer; this has occasionally been misinterpreted as Jachmann himself receiving a magister degree).
Jachmann’s older brother, who had been serving as Kant’s amanuensis, left for Edinburgh in the summer of 1788, and these secretarial duties may well have passed on to Jachmann for the remaining six years of his stay in Königsberg, which would have provided him with free meals at the university (each member of the academic senate was given support for one amanuensis). During this time he began theological studies and applied unsuccessfully for the diaconate of the Altstadt Church. With the help of C. J. Kraus [bio] he finally received a position in Marienburg (a city 50 km south-east of Danzig) as rector of the school and 3rd pastor of the church, beginning in February 1794, although already by June he was writing to Kant of his hope to marry and return to Königsberg, if only Kant could persuade Hippel to help him secure a position there (letter of 4 June 1794). He did in fact marry that year, but received no offer from Königsberg. Three years later (letter of 19 October 1797), Jachmann asked Kant for advice in finding another pastoral position in Königsberg as well as a teaching position in the philosophy faculty; again, nothing came of that, although Kant did forward a book to him written by Karl Arnold Wilmans (The Similarity of Pure Mysticism with the Religious Doctrine of Kant, 1797), with the suggestion that he write a reply (#831, 1798?; AA 12:273). Jachmann’s reply appeared in 1800 with a preface by Kant [writings], and in it Jachmann rejects Wilman’s claim that the Kantian philosophy of religion is compatible with mysticism and special revelation.
In 1801 Jachmann was made director of the Conrad Provincial School and Pedagogical Institute in Jenkau (also near Danzig), and with Johann Wilhelm Süvern he wrote up a plan of educational reform for all Prussia, including a thorough-going reform of the Gymnasia. In 1812 Jachmann co-published (with his colleague Franz Passow) the Archiv deutscher Nationalbildung, with contributions from Fichte, F. A. Wolf, Johann Schulze, J. G. Scheffner, and others, with his own essays on national education displaying a decidedly Fichtean influence. In 1814 he was appointed government and school advisor in Gumbinnen, where he also formed a Friedensgesellschaft to support gifted youth, and he founded a similar society when he moved to Danzig in 1816 to work under von Schön in the new Prussian government and where he was to direct the entire educational system of West Prussia. The university in Breslau conferred the Ph.D. on him in 1817. With the unification of West and East Prussia, Jachmann moved in 1832 to Königsberg to serve as provincial school advisor and privy government advisor.
Jachmann’s biography of Kant (1804) was begun in 1800 or earlier at Kant’s request, and for which he solicited Kant’s written help with a list of 56 questions, although Kant was unable to answer them for lack of strength (cf. AA 12:321-24, and the preface to Jachmann 1804).
