Albert Einstein (1879-1955) was a German physicist based in the United States.
Very early in his life, he expressed curiosity about science: at age five, when he was given a compass as a gift, he marveled at the instrument.
Since then, Einstein has decided never to move away from science. He was best known for developing the theory of relativity. He won the 1921 Nobel Prize in Physics for his correct explanation of the photoelectric effect; however, the award was only announced in 1922. His theoretical work enabled the development of the atomic energy, although it does not provide for such a possibility.

Due to the formulation of the theory of relativity Einstein became famous worldwide. In his later years, his fame exceeded that of any other scientist in popular culture: "Einstein" has become a synonym for genius. He was for example elected by Time magazine as the "Person of the Century" and his face is one of the best known in the world. In 2005 the International Year of Physics was celebrated, commemorating the 100th anniversary of Einstein's so-called "Annus Mirabilis" (Miraculous Year), in which he published four of the most important scientific articles of twentieth-century physics. In his honor, his name was given to a unit used in photochemistry, the einsteinas well as a chemical element, the einstenium.
