Albert Einstein (14 March 1879 – 18 April 1955) was a German-born 
theoretical physicist who developed the theory of relativity, one of the two 
pillars of modern physics (alongside quantum mechanics). His work is also known 
for its influence on the philosophy of science. He is best known to the general 
public for his mass–energy equivalence formula E = mc2, which has been dubbed 
"the world's most famous equation". He received the 1921 Nobel Prize in Physics 
"for his services to theoretical physics, and especially for his discovery of 
the law of the photoelectric effect", a pivotal step in the development of 
quantum theory. (Quoted from Wikipedia.org)
