11757 Salpeter           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Edwin E. Salpeter (b. 1924), born in Austria, educated in Australia and the U.K., has been at Cornell University since 1948. A generalist, he worked with Hans Bethe in quantum electrodynamics and nuclear physics and is best known for the triple- \alpha helium-burning reaction and for the initial mass function of stars.
