Albert Einstein (1879-1955) was a German born Nobel Prize winning physicist famous for several great works of theoretical physics. He is perhaps best known for his theories of Special Relativity and General Relativity, but his accomplishments include many other important works, such as the Photoelectric Effect, Brownian Motion, Bose-Einstein Statistics, his critiques of quantum mechanics via the EPR-Paradox, and later in life, his work in search of a Unified Field Theory.
