Albert Einstein is one of the best known physicists of all times.
He was a German-born theoretical physicist who developed the general theory of relativity, one of the two most important areas of modern physics, the other being quantum physics. Notably he received his Nobel Prize for Physics in 1921 for services to theoretical physics and his discovery of photoelectric effect, which also led to the establishment of quantum mechanics!
He was born in Ulm in the German Empire and died in Princeton, New Jersey, USA (aged 76).
His energy-mass equivalence formula is known to many and is now a part of modern popular culture. E is energy, m mass and c the speed of light.
