Albert Einstein:

Albert Einstein was born at Ulm, Germany, on March 14, 1879. He trained as a teacher, but after receiving his diploma from the Swiss federal Polytechnik in Zurich, he worked in the patent office in Berne. In his spare time, he wrote four scientific papers, which, when published in 1905, led to his recognition as one of the world's greatest scientists.

He subsequently emigrated to the United States, and became Professor at Princeton University. During the Second World War, he led a group of concerned scientists who persuaded President Roosevelt of the United States to order the construction of an atomic bomb, as there was a danger of Nazi Germany developing the technology first. He died in Princeton on April 18, 1956.

His major work concerned the Theory of Relativity, Statistical Mechanics, and the Photon Theory of Light, for which he was awarded the Nobel Prize for Physics in 1922.

He is also remembered for his dedication to social justice and his support for Jewish refugees from Nazi Germany.
