Friedrich Johann Buck was born (12 November 1722) and died (4 August 1786) 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. Unlike Kant, he was also musically talented.
Buck entered the Collegium Fridericianum gymnasium in Königsberg in 1732 — the same year as Kant, who was two years his junior, but Buck left for the university three years earlier, on 4 June 1737, where he studied law, theology, and anatomy, but especially philosophy and mathematics under Martin Knutzen [bio] (1713-1751), who had recently begun his lecturing career as an associate professor in logic and metaphysics. Buck received his magister degree, and then habilitated on 18 July 1743, and that fall began a successful teaching career in Königsberg. He was still working as a Privatdozent when Knutzen died mid-semester on 29 January 1751; Buck assumed responsibility for Knutzen’s classes, as well as for his scientific correspondence, at the request of Knutzen’s widow. Buck was appointed associate professor of mathematics beginning SS 1753, and then full professor of logic and metaphysics beginning SS 1759, replacing J. D. Kypke [bio], and being favored over Kant, who had also applied for the position [more]. In 1747 he was also appointed assistant librarian at the city library (replacing G. B. Casseburg [bio]), and in 1782 was made first librarian (replacing T. C. Lilienthal [bio]), a post held until his death. He was awarded a doctorate of law in absentia in April 1748 from the university at Frankfurt/Oder, with a dissertation on Roman law, although he offered no courses in the law faculty.
The mathematics chair became vacant in 1770 with the death of Professor Langhansen [bio] and Kant arranged, through a bit of intrigue, for the government to offer this chair to Buck, and then to offer Buck’s vacated chair of logic and metaphysics to Kant [more]. Either willingly or not, Buck accepted these changes, becoming the full professor of mathematics beginning with summer semester 1770, although he continued to offer private lectures in metaphysics, logic, practical philosophy, and experimental physics. He had been using Crusius’s texts in his logic and metaphysics lectures, but changed in WS 1770/71 to J. G. H. Feder’s Logik und Metaphysik im Grundriß (Göttingen, 1769). The required public lectures in mathematics were on arithmetic and geometry during the summer semesters and trigonometry and astronomy during the winter, and for both of these it appears he used Wolff’s popular Auszug (Halle, 1717), the same text Kant had used in his mathematics lectures.
Buck had accumulated a collection of over 550 scientific instruments, which were auctioned at his death. He was an honorary member of the Cosmographischen Gesellschaft of Nurnberg, the German Society at Frankfurt/Oder, and the Latin Society of Altdorf. He was a diligent lecturer as well as author; Goldbeck (1781) lists thirty publications.
