a German chemist and engineer, renowned as co-discoverer of a new process for the synthesis of ammonia— the basis of modern fertilizer production. Teaming with Fritz Haber from 1908-1913, Bosch discovered how to synthesize ammonia on a large industrial scale. The two then went on to work out methods for the industrial production of nitrogen fertilizers, thus providing practically every country in the world with sufficient fertilizers for agricultural purposes. In 1931 Bosch was awarded the Nobel Prize for Chemistry, jointly with Friedrich Bergius, for their contributions to the invention and development of chemical high-pressure methods.
