Ferdinand Caspary
Ferdinand Caspary (born December 29, 1853 in Unruhstadt , † July 15, 1901 in Berlin ) was a German mathematician.
Life
Caspary grew up as the son of a Jewish merchant (his grandfather was a rabbi) in Glogau and attended the Protestant grammar school there. After graduating from high school in 1871, he vacillated between mathematics and classical philology. He studied mathematics at the University of Berlin with Karl Weierstraß , Ernst Eduard Kummer , Leopold Kronecker and physics with Hermann von Helmholtz and heard the lectures of Siegfried Heinrich Aronhold and Karl Wilhelm Pohlke on perspective at the Bauakademie at the industrial academy. In 1875 he received his doctorate from Kummer with a geometric thesis.
In 1877 he became a teacher at the Humboldt Gymnasium in Berlin. In 1886/87 he took leave for scientific work and went to Paris , where he came into contact with Charles Hermite , with whom he became friends, and Gaston Darboux . Back in Berlin he gave up his post at high school and taught at vocational schools, while at the same time intensifying his scientific work and publishing a lot in French journals. In 1892 he visited Hermite again in Paris.
From 1893 he worked as a mathematician at Siemens and Halske and headed their patent office in Charlottenburg. Most recently he was chronically ill as a result of overwork, but went to Paris on behalf of Siemens again a year before his death.
As early as the 1870s, he was concerned with the methods of Hermann Graßmann and his theory of expansion , that is, with early vector calculation . He also dealt with theta functions , which he applied in mechanics and geometry.
