Ludwig Adolf[a] Sohncke (20 June 1807 in Königsberg (now Kaliningrad), Kingdom of Prussia – 16 January 1853 in Halle, Kingdom of Prussia) was a German mathematician. He was father of the mathematician Leonhard Sohncke.
Life and work edit
Ludwig Adolf Sohncke studied at the Albertina University in his native town Königsberg, was doctoral student of Carl Gustav Jacob Jacobi.[1] There he began his scientific career as private lecturer in 1833. Together with Jacobi and Franz Ernst Neumann, he was co-founder and co-director of the Königsberg Seminar of Physics that aimed to install a more intensive and effective model for teaching Physics and mathematics.[2] In this institution, Otto Hesse and Theodor Schönemann belonged to his students.[3]
In 1835, he was claimed — by recommendation of Friedrich Wilhelm Bessel — to the University of Halle as extraordinary professor of mathematics in succesion of Julius Plücker,[4] where he advanced to ordinary professor in 1839. He worked with varied interests in analysis, mainly in the field of elliptic functions, where he made discoveries over the complex multiplication,[5] further in geometry, mechanics, and history of mathematics.[6] He translated the History of Geometry by Michel Chasles (1837) into the German ,language,[7] and edited some of his analytic lectures. Seen as a whole, his list of publication is small;[8] possible reasons could be difficult economic condition,[9] since the payments for professors in Halle were low and often was not enough for their living[10], or a great burden of teaching, or a problem with alcohol.[9]
Together with his colleague Kämtz, Sohncke made an attempt in 1837 to found a seminar for mathematics and physics similar to that he had been co-founder in Königsberg, but their initiative was opposed by the biologist Schweigger. After long negotiations, a "Seminar für Mathematik und die gesammten Naturwissenschaften" (Seminar for Mathematics and whole Sciences) was founded with Sohnche as head of the mathematical division; later he became director of the seminar.[11] Although it brought out considerable success, it never got the importance of the Königsberg seminar.[12]
Ludwig Adolf Sohncke died in Halle on 16 January 1853; his academic successor was Ferdinand Joachimsthal.[13]
