Carl Bosch (1874-1940), German industrial chemist. Bosch worked with Fritz Haber to develop the Haber-Bosch process, which they patented in 1910. This is a high pressure chemical reaction used to produce ammonia. It was used extensively by the Germans during World War I, the ammonia being used to make nitric acid for the manufacture of explosives. After the war he worked on high pressure syntheses of petrol and methanol. For his development of high pressure chemistry, he was awarded the 1931 Nobel Prize for Chemistry. In 1925 he was one of the founders of the WWII German chemical giant IG Farben, and was chairman of the board of directors from 1935.
