[1] The Haber–Bosch process produces ammonia from hydrogen and atmospheric nitrogen.
It was first demonstrated in 1909 and became an important industrial process for Germany during World War One when it played a part in the manufacture of explosives.
The Bergius process produces hydrocarbon fuel from bituminous coal and hydrogen.
The process was first published in 1913 and was an important source of fuel for Germany during World War Two.
The invention and development of these two processes led to the award of the Nobel Prize in Chemistry for 1931 jointly to Friedrich Bergius and Carl Bosch.
