Physicist (solid state physics, ferromagnetism). Born in Cologne, Germany in 1900, Ernst Ising received his Doctorate of Natural Sciences from the University of Hamburg in 1924. His thesis proposed what became known as the Ising Model, a groundbreaking theory explaining transitions from one phase to another, specifically applied to ferromagnetism. Ising was Jewish but his wife was not. He curtailed his career and was persecuted with the rise of National Socialism, while his wife saved him from the camps. After emigrating to the United States in 1947, Ernst Ising developed a reputation as an exemplary teacher and concentrated his efforts in that area rather than in research. Professor, Bradley University from 1948.
