Johannes Stark

Johannes Stark was a German physicist who won the Nobel Prize in Physics in 1919 for discovering the Stark effect, which is how atomic spectral lines shift when exposed to electric fields. His work helped deepen understanding of atomic structure and how atoms interact with electric forces. However, Stark’s later associate with Nazi ideology and anti-Semitic views has marred his legacy, making him a controversial figure. While his scientific contributions are significant, his political affiliations tarnished his reputation in the scientific community.
