Carl BoschDied 26 Apr 1940 at age 65 (born 27 Aug 1874). German industrial chemist who at BASF directed development of the industrial scale process for production of ammonia from atmospheric nitrogen. In 1908, Fritz Haber, a professor of chemistry had suggested that nitrogen and hydrogen gases could be combined using high temperatures, high pressure and catalysts that resulted in the Haber-Bosch process. By 1910, Alwin Mittasch (1869-1953), head chemist of the BASF ammonia research laboratory identified activated iron as a suitable catalyst. Bosch supervised creation of new technical solutions for high pressure operations. He shared (with Friedrich Bergius) the 1931 Nobel Prize for Chemistry for devising chemical high-pressure methods.« |
