Oswald Veblen

Died 10 Aug 1960 at age 80 (born 24 Jun 1880).American mathematician who made important contributions in early topology, and in projective and differential geometry - work which found applications in atomic physics and the theory of relativity. In 1905, he proved the Jordan curve theorem, which states that every non-self-intersecting loop in the plane divides the plane into an "inside" and an "outside". Although it may seem obvious in its statement, it is a very difficult theorem to prove. During WW II, he was involved in overseeing the work that produced the pioneering ENIAC electronic digital computer. His name is commemorated by the American Mathematical Society's Oswald Veblen Prize. Awarded every five years, it is the most prestigious award in recognition of outstanding research in geometry.«
