Albert Einstein (1879-1955) is universally known for formulating a general theory of relativity (E=mc2). Einstein's theory made gravitation a factor in determining the curvature of a space-time continuum and helped land him the Nobel Prize for Physics in 1921. This honor failed to deter the Nazis from confiscating his property, and in 1934, Einstein, who was Jewish, was deprived of German citizenship. This led him to accept a position at the Institute for Advanced Study at Princeton, where he worked on a unified field theory until his death.
