Ernst Ising

Ernst Ising (1900 to 1998) was a German physicist who is best remembered for the development of the Ising model, a mathematical model of ferromagnetism that carries his name. He was born on 10 May 1900 and died on 11 May 1998, one day after his ninety-eighth birthday. His doctoral thesis, completed at the University of Hamburg in 1924, was titled Contribution to the Theory of Ferromagnetism. He later worked in the United States, where he was a professor of physics at Bradley University in Peoria, Illinois until his retirement in 1976. The model that bears his name has remained a standard subject in statistical mechanics and mathematical physics.
