15262 Abderhalden           Discovered 1990 Oct. 12 by F. Borngen and L. D. Schmadel at Tautenburg.
Swiss physiologist Emil Abderhalden (1877-1950) lectured at the University of Halle during 1911-1945. He contributed more than 1000 articles to the physiologic chemistry of metabolism, created the basis of modern dietetics, discovered the defensive enzymes against exogenous proteins and promoted social welfare.
