Bosch, Karl (1874–1940)
Karl Bosch was a German industrial chemist who adapted the Haber process for ammonia manufacture for large-scale industrial use. Bosch's work involved finding metallic catalysts that could promote this high-pressure synthesis. His invention of the Bosch process (in which water gas and steam at high temperatures are passed over a catalyst) aided the large-scale prepared of hydrogen. He shared the 1931 Nobel Prize in Chemistry, with Friedrich Bergius, for his work on high-pressure synthesis.
