Franz Joseph Emil Fischer (19 March 1877 in Freiburg im Breisgau – 1 December 1947 in Munich) was a German chemist. He was the founder and first director of the Kaiser Wilhelm Institute for Coal Research. He is known for the discovery of the Fischer–Tropsch process.[1]


In 1925, he and Hans Tropsch discovered the Fischer–Tropsch process. This allowed for the production of liquid hydrocarbons from carbon monoxide and hydrogen with metal catalyst at temperatures of 150–300 °C (302–572 °F).

In 1930, he and Hans Schrader developed the Fischer assay, a standardized laboratory test for determining the oil yield from oil shale to be expected from a conventional shale oil extraction.[2] He also worked with Wilhelm Ostwald and Hermann Emil Fischer.[3] In 1913, he became the Director of the Kaiser Wilhelm Institute for Coal Research in Mülheim.

He joined the NSDAP in 1933, and remained in office until his retirement in 1943.
