31665 Veblen           Discovered 1999 May 10 by P. G. Comba at Prescott.
Oswald Veblen (1880-1960) was a professor at Princeton and later at the Institute for Advanced Study. Known for the clarity of his exposition, he made important contributions to topology, projective geometry and differential geometry, and he was a mentor to generations of mathematicians.
