Christoffel, Elwin Bruno

 

Born Nov. 10, 1829, in Monschau; died Mar. 15, 1900, in Strasbourg. German mathematician.

In 1862, Christoffel was appointed a professor at the Polytechnikum in Zurich and in 1872 at the University of Strasbourg. He is best known for studies in the theories of functions, of partial differential equations, of invariants of algebraic forms, and of quadratic differential forms, where he introduced the symbol that bears his name (see).
