Otto Haupt

Otto Haupt (1887 to 1988) was a German mathematician who specialized in geometry and real analysis. Born in Wuerzburg, he obtained his doctorate there in 1911 under the supervision of Georg Rost and Emil Hilb and later became a professor at the University of Erlangen-Nuremberg, where he taught until his retirement in 1953 and continued his research for many years afterwards. Many of his research publications related to the four-vertex theorem on local minima and maxima of curvature, and he also wrote textbooks on algebra and calculus. He received honorary doctorates from the universities of Bonn, Nantes and Wuerzburg, and in 1987, the year of his hundredth birthday, a conference was held in his honour at Erlangen. He died in Bad Soden in November 1988. Among his students at Erlangen was Heinz Bauer.
