Johannes Stark was born in Schickenhof, Germany, on 15th April, 1874. He was educated at the local grammar school in Bayruth before attending the University of Munich to study physics, mathematics and chemistry.
After graduating in 1897 Stark worked at the Physics Institute in Munich until becoming a lecturer of physics at the University of Gottingen (1900-1906) and professor of physics at the Technische Hochschule in Hannover (1906-1909).
Stark correspondence with Albert Einstein and this resulted in him exploring what became known as the light quanta hypothesis. In 1913 Stark modified the photo-equivalence law that had been proposed by Einstein seven years earlier.
In 1919 Stark discovered the splitting of spectral lines in a electric field and six years later won the Nobel Prize for Physics as a result of his work on electro-magnetism.
In 1922 Stark published The Present Crisis in German Physics (1922). The book contained a scathing attack on Einstein's theory of relativity. He also criticized
