Karl Gustav Reuschle

from Wikipedia, the free encyclopedia

Karl Gustav Reuschle , also Carl Gustav Reuschle, (born December 26, 1812 in Mehrstetten , † May 22, 1875 in Stuttgart ) was a German mathematician, geographer and educator.

Life

Reuschle studied mathematics and theology at the University of Tübingen and after graduating in theology he went to Paris for one year and then to Berlin to study mathematics. After graduating, he worked as a teacher from 1837, first as a repentant at the seminar in Schöntal and in 1838/38 at the Tübingen monastery . In 1840 he became a professor of mathematics, physics and geography at the grammar school in Stuttgart.

He wrote several geographic textbooks (including an edition of Alexander von Humboldt's Kosmos for schoolchildren) and a biography of Johannes Kepler . a. was praised by Max Caspar . He was in correspondence with Ernst Kummer . Shortly before his death, he published a table of prime numbers in these number fields, which he had worked on for years, based on Kummer's theory of circular fields. Kummer himself also worked on such tables, but did not publish them. Both were also influenced by the calculations of tables by Carl Gustav Jacobi in his Canon arithmeticus . Reuschle's book was known to the mathematician Harry Vandiver , who himself performed early computer calculations in the vicinity of Fermat's Great Theorem.

His son Karl Reuschle (1847–1909) was also a mathematician who was associate professor from 1872 and professor at the Polytechnic in Stuttgart from 1893, where he led the first mathematics seminar at the University of Stuttgart with Rudolf Mehmke from 1899. He received his doctorate in Tübingen in 1882 and was also a teacher.
