Leopold Vietoris

Leopold Vietoris (Radkersburg, June 4, 1891 - Innsbruck, April 9, 2002) was an Austrian mathematician who gained additional fame by becoming a supercentenarian (especially for a male).

He was known for his contributions to topology and other fields of mathematics, his interest in mathematical history and for being a keen alpinist. Vietoris attended the University of Vienna, where he earned his Ph.D in 1920. With his wife Maria Josefa Vincentia, born von Riccabona zu Reichenfels (July 18, 1901 - March 24, 2002), dying at age 100, they became one of the eldest couples of the world, having the sixth highest aggregate age of a married couple (total combined age).

He lends his name to a few mathematical concepts:
*Vietoris topology (see topological space)
*Vietoris homology (see homology theory)
*Mayer-Vietoris sequence
*Vietoris-Begle mapping theorem
*Vietoris–Rips complex

Vietoris lived to be 110 years and 309 days old, and became the oldest known Austrian man ever. In doing so, he also is a rare example of a supercentenarian already known for some other achievement.
