Albert Einstein dies in Princeton, New Jersey (born in Ulm, Germany). As a child, Einstein lived in Munich, Milan and Zürich. He taught for a time at the polytechnic in Zürich. In 1914, having established a reputation, he accepted a position at the Prussian Academy of Sciences in Berlin. A life-long pacifist he opposed World War I and when Adolf Hitler came to power in 1933, at age 54, he rejected his German citizenship and immigrated to the United States. In America he accepted a research position at the Institute for Advanced Study in Princeton, New Jersey. Although he was a pacifist, he was so horrified by the Nazis that he urged armament for the other European nations to resist Germany. When he became aware of the work Hahn, Strassmann and Meitner were doing with nuclear fission, he urged President Roosevelt to immediate action in atomic research.
