PINNER, ADOLF (1842–1909), German organic chemist. Born in Wronke, then Germany, he studied for the rabbinate, but changed to chemistry. He was a professor at Berlin University from 1878 and also taught at Tieraertzliche Hochschule. He was director of the Patent Office of Ministry of Commerce (1885–1907). Pinner published extensively on organic chemistry topics, particularly alkaloids. His Repetitorium der organischen, beziehungsweise anorganischen Chemie (2 vols., 1872–73) was a standard textbook for many years. He also wrote Die Imidoaether (1892).
