9260 Edwardolson           Discovered 1953 Oct. 8 at the Goethe Link Observatory, Indiana University.
Edward C. Olson (b. 1930), emeritus professor at the University of Illinois, has carried out observational programs that have demonstrated how the outer layers of mass-gaining stars are distorted, and how angular momentum from the mass-transfer process can spin stars up close to the stability limit.
