Erwin Schrödinger

Erwin Rudolf Josef Alexander Schrödinger (12 August 1887 – 4 January 1961), sometimes anglicised as Schroedinger or Schrodinger, was an Austrian theoretical physicist who developed fundamental results in quantum theory. In particular, he is recognized for devising the Schrödinger equation, an equation that provides a way to calculate the wave function of a system and how it changes dynamically in time. He coined the term "quantum entanglement" in 1935. Schrödinger shared the 1933 Nobel Prize in Physics with Paul Dirac "for the discovery of new productive forms of atomic theory".

In addition, Schrödinger wrote many works on various aspects of physics: statistical mechanics and thermodynamics, physics of dielectrics, color theory, electrodynamics, general relativity, and cosmology, and he made several attempts to construct a unified field theory. In his book, What Is Life?, Schrödinger addressed the problems of genetics, looking at the phenomenon of life from the point of view of physics. He also paid great attention to the philosophical aspects of science, ancient and oriental philosophical concepts, ethics, and religion. He also wrote on philosophy and theoretical biology. In popular culture, he is best known for "Schrödinger's cat", a thought experiment. He and Dirac tied for eighth in a Physics World poll of the greatest physicists of all time.

In his personal life, he lived with both his wife and his mistress which may have led to problems causing him to leave his position at Oxford. Subsequently, until 1938, he had a position in Graz, Austria, until the Nazi takeover when he fled, finally finding a long-term arrangement in Dublin, Ireland, where he remained until retirement in 1955. He returned to Vienna in 1956, with an emeritus professor position, and died of tuberculosis in 1961. In 1989, allegations of sexual abuse of several minors emerged. In 2026, a defence was published challenging some of these allegations.
