This method was developed by Hofmann in 1868, who replaced the short tube of Gay-Lussac by an ordinary barometer tube, thus effecting the volatilization in a Torricellian vacuum.
In 1842 he became professor ordinarius at Rostock, but in 1845 returned once more to Erlangen as the successor of Gottlieb Christoph Adolf von Harless (1806-1879), founder of the Zeitschrift fur Protestantismus and Kirche, of which Hofmann became one of the editors in 1846, J.
MELCHIOR HOFMANN (c. 1 49 8 - 1 543-4), anabaptist, was born at Hall, in Swabia, before 1500 (Zur Linden suggests 1498) .
For Melchior Hofmann (ca.
Mitscherlich prepared it in 1834 by distilling benzoic acid with lime; and in 1845 Hofmann discovered it in coal-tar.
Later followed men like Hengstenberg, Homeyer, Bethmann-Hollweg, Puchta, Stahl and Heffter; Schelling, Trendelenburg, Bopp, the brothers Grimm, Zumpt, Carl Richter; later still, Twesten and Dorner, Gneist and Hinschius; Langenbeck, Bardeleben, Virchow, Du-Bois Reymond; von Ranke, Curtius, Lipsius, Hofmann the chemist, Kiepert the geographer; Helmholtz, van't Hoff, Koch, E.
That city possesses a permanent memorial to his name in Hofmann House, the home of the German Chemical Society (of which he was the founder), which was formally opened in 1900, appropriately enough with an account of that great triumph of German chemical enterprise, the industrial manufacture of synthetical indigo.
JOHANN CHRISTIAN KONRAD VON HOFMANN (1810-1877), Lutheran theologian and historian, was born on the 21st of December 1810 at Nuremberg, and studied theology and history at the university of Erlangen.
The college to which Hofmann devoted nearly twenty of the best years of his life was starved; the coaltar industry, which was really brought into existence by his work and that of his pupils under his direction at that college, and which with a little intelligent forethought might have been retained in England, was allowed to slip into the hands of Germany, where it is now worth millions of pounds annually; and Hofmann himself was compelled to return to his native land to find due appreciation as one of the foremost chemists of his time.
In theology, as in ecclesiastical polity, Hofmann was a Lutheran of an extreme type, although the strongly marked individuality of some of his opinions laid him open to repeated accusations of heterodoxy.
