Portrait of Albert Einstein, probably taken in 1921 by Schloss of New York. Einstein was born at Ulm, Germany on March 14, 1879. Encouraged by his father, who was an electrical engineer, Einstein studied at the Zurich Polytechnic Institure until the age of 21. Shortly afterwards he started working at the Swiss Patent Office. Although famous for his papers on special and general relativity, he won the 1921 Nobel Prize for physics for his work on the photoelectric effect. Einstein died on April 18, 1955 without completing his grand unified Theory of the Fundamental forces, which remains uncompleted by today's theoretical physicists.
