Leroy Milton Kelly

Leroy Milton Kelly (May 8, 1914 – February 21, 2002 ) was an American mathematician whose research primarily concerned combinatorial geometry. In 1986 he settled a conjecture of Jean-Pierre Serre by proving that n points in complex 3-space, not all lying on a plane, determine an ordinary line—that is, a line containing only two of the n points. He taught at Michigan State University.

Kelly received his Ph.D. at the University of Missouri in 1948, advised by Leonard Mascot Blumenthal.
