Albert Einstein

Albert Einstein was considered the greatest scientist of the 20th century and one of the greatest of all time. His discoveries and theories have greatly influenced science in many fields.
Einstein was born in 1879 in Ulm, a city in Germany. As a boy, he was slow to learn to talk, but later in his childhood he showed great curiosity about nature and ability to solve difficult mathematical problems. After he left school, he went to Switzerland, where he graduated from the university with a degree in mathematics.
In 1905, Einstein began to publish a series of papers which shook the whole scientific and intellectual world, and for the theories he established in the papers he won the Nobel Prize for Physics in 1921.
Because Einstein was Jewish, when Hitler took over Germany in 1933, he had to leave the country and finally settled in the United States. There he continued his study on the structure of the universe until his death in 1955.
Among the several important discoveries Einstein made in his life, the greatest is the creation of his famous Theory of Relativity
