Rudolf Lipschitz

Rudolph Otto Sigismund Lipschitz (May 14, 1832 - October 7, 1903) was a German mathematician, professor at the University of Bonn from 1864. He supervised the early work of Felix Klein. Lipschitz named the Lipschitz continuity condition after him, and he worked in a wide range of areas, including number theory, algebras with involution, mathematical analysis, differential geometry, and classical mechanics.
