About Albert Einstein

Albert Einstein (14 March 1879 – 18 April 1955) was a Jewish 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.
