Johannes Stark
Johannes Stark (5 April 1874 – 21 June 1957) was a German physicist who won the 1919 Nobel Prize for Physics for his discovery of the Stark effect.
A supporter of Adolf Hitler from 1924, Stark was one of the main figures, along with fellow Nobel laureate Philipp Lenard, in the Deutsche Physik movement. In 1947, Stark was classified as a "Major Offender" and received a sentence of four years' imprisonment (later suspended) by a "denazification" court.
