Ludwig Danzer

Ludwig Danzer was a German geometer working in discrete geometry. He was a student of Hanfried Lenz, starting his career in 1960 with a thesis about "Lagerungsprobleme".
Danzer's name is popularized in the concepts of a Danzer set, a set of points that touches all large convex sets, and the Danzer cube, an example of a non-shellable triangulation of the cube. It is an example of a power complex, studied by Danzer in the 1980s.
Danzer also found many new tilings.
Ludwig Danzer worked at the Technical [University of Dortmund] and died on December 3, 2011, after a long illness.
Danzer had at least ten students, the most prominent one being Egon Schulte.
