german-born theoretical physicist (1879–1955)
Albert Einstein (14 March 1879 – 18 April 1955) was a German theoretical physicist, widely acknowledged to be one of the greatest physicists of all time. Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Together, relativity and quantum mechanics are the two pillars of modern physics. He won the 1921 Nobel Prize in Physics for his explanation of the photoelectric effect.

Everything that the human race has done and thought is concerned with the satisfaction of deeply felt needs and the assuagement of pain. One has to keep this constantly in mind if one wishes to understand spiritual movements and their development. Feeling and longing are the motive force behind all human endeavor and human creation, in however exalted a guise the latter may present themselves to us.
