Ferdinand Joachimsthal

Ferdinand Joachimsthal ( born March 9, 1818 in Goldberg i Silesia, † April 5, 1861 in Breslau) was a German mathematician.

Joachimsthal went to high school in Legnica, where Ernst Eduard Kummer was his mathematics teacher. From 1836 he studied mathematics at the University of Berlin among others Dirichlet and Jakob Steiner, 1838 at the University of Königsberg at Carl Gustav Jacobi and Friedrich Wilhelm Bessel and at the University of Halle, where he received his doctorate in 1840. From 1844 he taught at the Royal Realschule in Berlin. In 1845 he completed his habilitation in Berlin ( De Curvis algebraicis ) and then taught at the University of Berlin and in 1847 he was at the French High School, where he became professor in 1852. In 1850 he habilitated in a second time in Breslau. In 1853 he became a professor in Halle and in 1855 as the successor of grief professor at the University of Breslau.

He dealt with differential geometry and analytic geometry in particular areas (for example normal on quadrics ) and was known for the high quality of his lectures, two of which were posthumously published as books.
