(1879 - 1955)
Born in Ulm, Würelemberg, Germany, he became an American theoretical physicist. He explained the Brownian motion and the photoelectric effect; contributed to the theory of atomic spectra, and formulated the theories of special and general relativity. He enjoyed classical music and played the violin. He supported world government, believing that peace among nations could be maintained in the atomic age only by bringing all people together under a system of world law.
In 1933, he joined the staff of the newly created Institute for Advanced Study in Princeton, New Jersey. He accepted this position for life, living there until his death. Einstein is probably familiar to most people for his mathematical equation about the nature of energy,
E = MC2.
