3. Life • Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy and Albert continued his education at Aarau, Switzerland and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he gained his diploma, he acquired Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he obtained his doctor's degree.

4. Early life and education • Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire on 14 March 1879. His father was Hermann Einstein, a salesman and engineer. His mother was Pauline Einstein (née Koch). In 1880, the family moved to Munich, where his father and his uncle founded ElektrotechnischeFabrik J. Einstein & Cie, a company that manufactured electrical equipment based on direct current. • The Einsteins were non-observant Jews. Albert attended a Catholic elementary school from the age of five for three years. At the age of eight, he was transferred to the Luitpold Gymnasium (now known as the Albert Einstein Gymnasium) where he received advanced primary and secondary school education until he left Germany seven years later. Contrary to popular suggestions that he had struggled with early speech difficulties, the Albert Einstein Archives indicate he excelled at the first school that he attended. He was right-handed; there appears to be no evidence for the widespread popular belief that he was left-handed.

5. World War II and the Manhattan Project • In 1939, a group of Hungarian scientists that included emigre physicist LeóSzilárd attempted to alert Washington of ongoing Nazi atomic bomb research. The group's warnings were discounted. Einstein and Szilárd, along with other refugees such as Edward Teller and Eugene Wigner, "regarded it as their responsibility to alert Americans to the possibility that German scientists might win the race to build an atomic bomb, and to warn that Hitler would be more than willing to resort to such a weapon.: On July 12, 1939, a few months before the beginning of World War II in Europe, Szilárd and Wigner visited Einstein and they explained the possibility of atomic bombs, to which pacifist Einstein replied: Daranhabeich gar nichtgedacht (I had not thought of that). Einstein was persuaded to lend his prestige by writing a letter with Szilárd to President Franklin D. Roosevelt to alert him of the possibility. The letter also recommended that the U.S. government pay attention to and become directly involved in uranium research and associated chain reaction research.

6. Theory of relativity and E = mc² • Einstein's "ZurElektrodynamikbewegterKörper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as Einstein's special theory of relativity. • Consequences of this include the time-space frame of a moving body appearing to slow down and contract (in the direction of motion) when measured in the frame of the observer. This paper also argued that the idea of a luminiferousaether – one of the leading theoretical entities in physics at the time – was superfluous. • In his paper on mass–energy equivalence Einstein produced E = mc2 from his special relativity equations.[97] Einstein's 1905 work on relativity remained controversial for many years, but was accepted by leading physicists, starting with Max Planck

7. Love of music • Einstein's gifts inevitably resulted in his dwelling much in intellectual solitude and, for relaxation, music played an important part in his life. He married MilevaMaric in 1903 and they had a daughter and two sons; their marriage was dissolved in 1919 and in the same year he married his cousin, Elsa Löwenthal, who died in 1936. He died on April 18, 1955 at Princeton, New Jersey.
