# Marcel Grossmann

Marcel Grossmann (Hungarian: Grossmann Marcell, April 9, 1878, Budapest – September 7, 1936, Zurich) was a mathematician of Jewish ancestry, and a friend and classmate of Albert Einstein. He became a Professor of Mathematics at the Federal Polytechnic Institute in Zurich, today the ETH Zurich, specializing in descriptive geometry.

It was Grossmann who emphasized the importance of a non-Euclidean geometry called elliptic geometry to Einstein, which was a necessary step in the development of Einstein's general theory of relativity. Abraham Pais's book on Einstein suggests that Grossman mentored Einstein in tensor theory as well.

Marcel Grossmann (1878-1936), 1920.

The community of relativists celebrates Grossmann's contributions to physics by organizing Marcel Grossman meetings every three years.
