Einstein's theories of special and general relativity drastically altered man's view of the universe, and his work in particle and energy theory helped make possible quantum mechanics and, ultimately, the atomic bomb.
After a childhood in Germany and Italy, Einstein studied physics and mathematics at the Federal Polytechnic Academy in Zurich, Switzerland. He became a Swiss citizen and in 1905 was awarded a Ph.D. from the University of Zurich while working at the Swiss patent office in Bern.
