Schrödinger, Erwin (1897-1961), the Austrian physicist who founded wave mechanics, a form of quantum mechanics. Following the suggestion made by the French physicist Louis de Broglie in 1924 that all particles have wave properties, Schrödinger in 1926 developed the Schrödinger wave equation. It is the basic equation in wave mechanics, used to calculate the amplitude of the wave associated with a particle. Schrödinger shared the 1933 Nobel Prize in physics with the British physicist Paul Dirac for the discovery of new forms of atomic theory, which were based on wave mechanics.

Schrödinger was born in Vienna and attended the University of Vienna. He taught physics at a number of European universities, including Zurich, Berlin, and Oxford.
