Walter Benz (May 2, 1931 Lahnstein â January 13, 2017 Ratzeburg) was a German mathematician, an expert in geometry.
Benz studied at the Johannes Gutenberg University of Mainz and received his doctoral degree in 1954, with Robert Furch as his advisor. After a position at the Johann Wolfgang Goethe University Frankfurt am Main, he served as a professor at Ruhr University Bochum, University of Waterloo, and University of Hamburg. Benz was honoured with the degree of a Dr. h.c.
Based on his book Vorlesungen über Geometrie der Algebren (Springer 1973), certain geometric objects are called Benz planes.
Inner product spaces over the real numbers provide the basis of a 2007 book by Benz: Classical Geometries in Modern Contexts.
