who became professor of physics at Berlin University in 1927. He left for Oxford to escape the Nazis in 1933, returned to Graz in Austria in 1936, and then left again in 1938 for Dublin’s Institute of Advanced Studies. He finally returned to Austria in 1956. He is best known for the development of wave mechanics and the Schrödinger equation in 1926, work that earned him a share of the 1933 Nobel Prize for physics with Paul Dirac. He was the first to use the word ‘entanglement’ in the context of quantum mechanics: See Quantum Entanglement (Feature).
