Leroy Milton Kelly
Leroy Milton Kelly (8 May 1914 – 21 February 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.
