15264 Delbrück           Discovered 1990 Oct. 11 by F. Borngen and L. D. Schmadel at Tautenburg.
German-born biophysicist Max Delbrück (1906-1981), who moved to the U.S. in 1937, was a cofounder of modern molecular biology and virus research. In 1969 he was a co-recipient of the Nobel Prize in medicine for the discovery of the genetic recombination of bacteriophages. The name was suggested by the first discoverer.
