He was the father of the neurobiologist Martin Heisenberg and the son of August Heisenberg. Werner Karl Heisenberg (German: [ËhaÉªzÉnbÉÉÌ¯k]; 5 December 1901 â 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper.
Those uncomfortable with Heisenberg's system jumped on the wave mechanics side. The conflict between the theories was resolved when SchrÃ¶dinger proved that they were, in fact, identical. In 1926 Heisenberg joined Bohr at the Institute for Theoretical Physics in Copenhagen. This turned out to be one of the most productive periods in Heisenberg's life. In 1927 he was puzzling over the basic quantum properties of electrons.
