In 1909 he took his discovery to the Badische Anilin- and Soda-Fabrik (BASF) where he and Carl Bosch developed a method of mass production, the Haber-Bosch Process. He won the Nobel Prize for Chemistry in 1918 for his work. During the Nazi years he was referred to as the “Jew Haber”. In 1933 he gave up his work in Germany and accepted a position at the University of Cambridge in England. He died in Basel of a heart attack on his way to a planned winter holiday in Italy.
