Michael O'Nan Wikipedia
Michael Ernest O'Nan (born August 9, 1943 in Fort Knox, Kentucky) is an American mathematician, specializing in group theory.
O'Nan received his PhD in 1970 from Princeton University under Daniel Gorenstein with thesis A Characterization of the Three-Dimensional Projective Unitary Group over a Finite Field. He is a professor at Rutgers University. In 1976 he found strong evidence for the existence of a sporadic group, which (O'Nan group) is named after him. The group was constructed by Charles Sims.
