obituary

Franz Varrentrapp (born August 29, 1815 in Frankfurt am Main ; † March 4, 1877 in Braunschweig ) was a German chemist and entrepreneur.

life and work

The son of the Frankfurt doctor Johann Conrad Varrentrapp (1779-1860) and Maria Christina, née Hofmann (1785-1859) completed an apprenticeship as a pharmacist in Lausanne from 1832 to 1835 . He then worked in pharmacies in Rastatt and Dresden before studying chemistry with Heinrich Rose and Eilhard Mitscherlich in Berlin from 1837 to 1839 . From 1839 to 1840 he continued his studies at the University of Giessen , where he did his doctorate under Justus von Liebig . In Giessen he and Heinrich Will developed the Will-Varrentrapp method for determining nitrogen . Research trips to England and Scotland followed in the autumn of 1840.

Activity in Braunschweig

Through the mediation of Liebig, who was friends with the Braunschweig publisher Eduard Vieweg , Varrentrapp became secretary of the trade association in Braunschweig in November 1841. There he supported industrialists and tradespeople as a business advisor. He suggested the preservation of asparagus in metal cans and thus founded the later flourishing canning industry in Braunschweig . In 1843 he married Elisabeth Kellner († 1850) in Frankfurt am Main. The following year, due to a vacancy, he became a teacher of physics and chemistry at the Anatomical-Surgical Institute . In 1846 he was appointed professor and in 1850 mining commissioner and coin validator . He carried out both tasks until the cessation of minting in 1860 and until the dissolution of the Anatomical Institute in 1869. In 1852 he married Dorette Krüger in Braunschweig for the second time. In 1868 he turned down a call to the newly founded Aachen Polytechnic. Varrentrapp, on the other hand, accepted the offer of his friend Heinrich Vieweg to become a partner in the publishers "Friedrich Vieweg und Sohn" and "Gebrüder Vieweg". He died in Braunschweig in 1877 after a long illness.

Others
