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]
