Werner Heisenberg (1901-1976)
Heisenberg was born in Duisverg, Germany, in December 15th 1901, and died in Munich, in February 1st 1976.
Studied theoretical physics in Munich. In Goettingen, as an assistant of Max Born (1924), Heisenberg proposed a matricial treatment of the atomic behavior. In 1925, with the help of Born and Jordan, developed this idea giving birth to a theory compatible with quantum mechanics. However, this theory, being hard to understand, was not very successful at the time.
In 1927, Heisenberg discovered the uncertainty principle and explained ferromagnetism based on the atomic structure. He was awarded the Nobel Prize of Physics in 1932. It was one of the few German scientists to remain in Germany during World War II.
