Description |
Framed photograph of Georg Bredig (1868-1944). Bredig is seated, wearing a suit and tie and his wedding ring. His shirt, which has a wing-tipped collar, was popular in early 20th century men's fashion. The photograph could be sepia-toned, or it has faded from its original black and white over time. Georg Bredig was a German physical chemist known for his work with catalysts, reaction kinetics, and electrochemistry. In 1898 he created Bredig's Arc method, which became the preferred chemical method for preparing colloidal solutions of metals. Bredig studied with a number of notable scientists including Wilhelm Ostwald (1853-1932), Jacobus Henricus van’t Hoff (1852-1911), Marcellin Berthelot (1827-1907) and Svante Arrhenius (1859-1927). He taught at the Technische Hochschule, Karlsruhe from 1911 until he was forced to resign in 1933 when the National Socialist party banned Jewish people from holding academic positions. In 1940 Bredig left Germany for the Netherlands and ultimately emigrated to the United States. |
