Weismann, August

Weismann, August ouˈgo͝ost vīsˈmän [key], 1834–1914, German biologist. He taught zoology at the Univ. of Freiburg from 1866 to 1912. He is known as the originator of the germ-plasm theory of heredity. His doctrine, formerly called Weismannism, stresses the unbroken continuity of the germ plasm and the nonheritability of acquired characteristics. His works include The Germ-Plasm (1892, tr. 1893) and a series of essays translated into English as Essays upon Heredity and Kindred Biological Problems (2d ed., 2 vol., 1891–92).
