Carl Bosch (27 August 1874–26 April 1940) was a German chemist and engineer and Nobel laureate in chemistry.

In 1899 he took an entry level job at BASF, then Germany's largest chemical and dye firm.
From 1909 until 1913 he transformed Fritz Haber's tabletop demonstration of a method to fix nitrogen using high pressure chemistry into an important industrial process to produce megatons of fertilizer and explosives.
In 1925 Bosch helped found and was the first head of IG Farben and from 1935 chairman of the board of directors.
He received the Siemens-Ring in 1924 for his contributions to applied research and his support of basic research.
In 1931 he was awarded the Nobel Prize in Chemistry together with Friedrich Bergius for the introduction of high pressure chemistry.
