Name:Named after Werner Carl Heisenberg (1901-1976), professor of physics in the universities of Leipzig, Berlin, Göttingen and Munich. Together with Born and Jordan, in parallel with the group around de Broglie, Dirac and Schrödinger, he lay the foundations of modern quantum mechanics. The uncertainty principle, formulated in 1927, was named after him. In 1932, he was awarded the Nobel prize in physics.
