Einstein, Albert

Albert Einstein was a physicist who was born in Ulm, Germany in 1879; he become a Swiss citizen in 1901 and left Germany for the United States in 1933, where he died in 1955.
He is most famous for developing the theory of Relativity, out of which came the famous equation E=mc².
In 1905 he suggested that light is absorted in the form of packets of Energy, now called photons; for this he received the Nobel Prize for Physics in 1921.
Also in 1905 he developed the special theory of relativity and later, in 1915, he arrived at the general theory of relativity.
These theories are the basis for all our ideas about the history and structure of the Universe.
Einstein's work on photons helped to found Quantum Theory, although he disagreed with some of the later work on this subject.
