Erich Schönhardt

Erich Schönhardt (born 25 June 1891 in Stuttgart, Germany, died 29 November 1979 in Stuttgart)[1][2] was a German mathematician known for his 1928 discovery of the Schönhardt polyhedron, a non-convex polyhedron that cannot be partitioned into tetrahedra without introducing additional vertices.[3]

Schönhardt studied at the University of Stuttgart,[2] and went on to do his graduate studies at the University of Tübingen, receiving his Ph.D. in 1920 for a thesis on Schottky groups[4] under the supervision of Ludwig Maurer.[2] In the 1930s, he was the Dozentenführer (Nazi political leader of the faculty) at Tübingen,[2][5] and was responsible for denouncing fellow Tübingen mathematician Erich Kamke for having married a Jewish woman.[5] He moved back to the University of Stuttgart in 1936[2] and was rector there from 1939–1942.[1][2][6] He was a permanent editor of the journal Deutsche Mathematik.
