Paul Ehrenfest, Austrian Physicist

Paul Ehrenfest (January 18, 1880 - September 25, 1933) was an Austrian-Dutch physicist who spent most of his career at Leiden University. His scientific papers dealt with fundamentals, and sought to clarify single points. His publications are renowned for clarity, by solving paradoxes, providing clearer descriptions, and inspiring by posing penetrating questions. His most important contribution is the theory of adiabatic invariants. He made major contributions to quantum physics, including the theory of phase transitions and the Ehrenfest theorem, which states that expectation values of a quantum system follow classical mechanics. He maintained a close relationship with Niels Bohr and Albert Einstein. It appears that Ehrenfest suffered from severe depression. By August 1932, Einstein was so worried that he wrote to the Board of the University of Leiden, expressing deep concern and suggesting ways in which Ehrenfest's workload could be reduced. In 1933, he lost his battle with depression. Having made arrangements for the care of his other children, he first shot his younger son Wassik, who had Down syndrome, then killed himself. He was 53 years old.
