Heinrich Wieland, 1877–1957, German chemist, Ph.D. Univ. of Munich, 1901. Wieland was a professor at the Technical Univ. of Munich from 1913 to 1921, the Univ. of Freiburg from 1921 to 1925, and the Univ. of Munich from 1925 to 1950. In 1927 Wieland received the Nobel Prize in Chemistry for determining the molecular structure of bile acids, which are produced by the liver. His work provided insight into the mechanism by which bile acids aid in the resorption of food in the intestines and led to the establishment of the close relationship between cholesterol and the bile acids.
