Werner Heisenberg (1901 - 1976)
Werner Heisenberg was born in Germany. Heisenberg's name will always be associated with his theory of quantum mechanics. For this theory, he was awarded the Nobel Prize for Physics for 1932. He is also known for the Uncertainty Principle.
Heisenberg was drafted by the Nazis to lead the German atomic bomb project. Heisenberg had spent the entire war working on a nuclear reactor, but had never accomplished a chain reaction.
