Prize motivation: "in recognition of their contributions to the invention and development of chemical high pressure methods."
Prize share: 1/2
After Fritz Haber developed a method for producing ammonia from nitrogen and hydrogen, which could then be used to manufacture artificial fertilizer, what remained was to develop it into an industrial process. Nitrogen and hydrogen gases require high pressure to react. Around 1913 Carl Bosch developed an apparatus that employed different types of steel with varying resistances to pressure and heat to create an efficient process. The result was also used in other chemical industry processes.
