Carl Gustav Reuschle

Karl Gustav Reuschle (26 December 1812 – 22 May 1875) was a German mathematician, geographer and educator.

Reuschle was born in Mehrstetten in Württemberg and studied math and theology at the University of Tübingen. After his graduation he continued his studies in mathematics for a year in Paris and for a year in Berlin. From 1837 onwards Reuschle worked as a teacher, first in Schöntal then in Tübingen (1938) and finally since 1840 at a gymnasium in Stuttgart, where he taught as professor for mathematics and geography.

Reuschle authored a number of science books, mostly on geography and mathematics. Particularly well received at the time was his biography of Johannes Kepler (1871). Reuschle died on 22 May 1875 in Stuttgart.

In elementary geometry Reuschle's theorem is named after him.
