Johannes Stark, German physicist, and Nobel Prize laureate was born today on 15th April 1874. A supporter of Adolf Hitler and an anti-Semitic racial theorist, Stark was president of the Reich Physical-Technical Institute from 1933 to 1939.

Born in Schickenhof, Kingdom of Bavaria, Stark was educated at the Bayreuth Gymnasium and later in Regensburg. Stark received his Ph.D. in physics from the University of Munich in 1897 under the supervision of Eugen von Lommel and served as Lommel's assistant until his appointment as a lecturer at the University of Gottingen in 1900.

He won the 1919 Nobel Prize for Physics for his discovery in 1913 that an electric field would cause splitting of the lines in the spectrum of light emitted by a luminous substance; the phenomenon is called the Stark effect.

To honor him Congo Postal Department has issued 350 Congolese Franc commemorative postage stamps in 2002.
