In History : Birth of Albert Einstein [ 14 March 1879 ]

Albert Einstein was a German-born theoretical physicist. He  was born in Ulm, in the Kingdom of Württemberg in the German Empire on 14 March 1879. His father was Hermann Einstein, a salesman and engineer. His mother was Pauline Einstein (née Koch). In 1880, the family moved to Munich, where his father and his uncle founded Elektrotechnische Fabrik J. Einstein & Cie, a company that manufactured electrical equipment based on direct current

He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).  While best known 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”. The latter was pivotal in establishing quantum theory.
