Albert Einstein (14 March 1879 - 18 April 1955) was a German-born theoretical physicist. A leading figure in theoretical physics throughout the early-mid 20th century, he is now one of most well-known and respected scientists of all time.
Einstein independently developed the theory of relativity, the backbone of modern physics, and received the Nobel Prize in Physics in 1921 both for discovering the photoelectric effect and his overall contribution to theoretical physics. Einstein is perhaps most well known for his equation E = mc2, the formula for mass-energy equivalence which shows that mass is directly related to energy.
