had two sons but eventually divorced. Einstein later remarried.After 1919, Einstein became internationally renowned. He accrued honors and awards, including the Nobel Prize in physics in 1921, from various world scientific societies. His visit to any part of the world became a national event; photographers and reporters followed him everywhere. While regretting his loss of privacy, Einstein capitalized on his fame to further his own personal and political views.The two social movements that received his full personal support were Pacifism, opposition to war and other violence, and Zionism, movement to unite the Jewish people of the Diaspora (exile) and settle them in Palestine. During World War I he was one of a handful of academics willing to publicly decry Germanys involvement in the war. After the war his continued support of Pacifist and Zionist goals made him the target of viscous attacks by anti-Semitic and right wing elements in Germany. Even his scientific theories were publicly ridiculed, especially the theory of relativity (Einstein, Albert).When Hitler came to power, Einstein immediately decided to leave Germany for the United States. He took a position at the Institute for Advanced Study at Princeton. While continuing his efforts on behalf of world Zionism, Einstein renounced his former Pacifist stand in the face of the awesome threat to humankind posed by the Nazi regime in Germany.In 1939 Einstein collaborated with several other physicists in writing a letter to President Franklin D. Roosevelt, pointing out the possibility of making an atomic bomb and the likelihood that the German government was embarking on such a course. The letter, which bore only Einsteins signature, helped lend urgency to efforts in the U.S. to build the atomic bomb, but Einstein played no role in the work and knew nothing about it at the time.After the war, Einstein was active in the case of international disarmament and world government.
