Born in Ulm, Germany, the young Einstein was dissatisfied with the restrictive schools in Germany. At the age of 16 he moved to Switzerland and graduated from the Federal Institute of Technology. In 1902 he became a clerk with Swiss Patent Office, where he worked with new inventions. In 1905 he published five papers, including the “Special theory of Relativity” which considered motion and the speed of light. The devastation of World War I caused Einstein to become an active pacifist. In 1916 he published his “General Theory of Relativity,” a concept of a curved universe and its affect on light. In 1922 he won the Nobel Prize for Physics. While visiting America in 1933 the Nazi party came to power in Germany and Einstein renounced his German citizenship for a second time. He chose to stay in America, accepting a position at Princeton University. During World War II, Einstein knew the Germans were working on the atomic bomb. He advised President Roosevelt of the dangers of the bomb in Nazi control. He appreciated that the United States had to develop it first, but begged Roosevelt not to use it. Einstein spent the rest of his life working for peace and died in 1955.
