ALBERT EINSTEIN (1879 – 1955) WAS A  GERMAN JEW,AMERICAN  CITIZENSHIP ,EXPERT,PHYSICIST AND GENIUS .HIS PLAN WAS TO DIVIDE HIS TIME BETWEEN GERMANY AND AMERICA.BUT IN THE SAME YEAR THE NAZI CAME TO POWER AND EINSTEIN BEING A JEW,NEVER RETURNED TO HIS BIRTHLAND.

Albert Einstein with his first wife Mileva Maric.So pragmatic was Einstein's approach to love that when he found his 11 year marriage to Mileva Maric floundering, he issued a list of outrageous rules he said would allow them to stay together.

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. During his stay at the Patent Office, and in his spare time, he produced much of his remarkable work and in 1908 he was appointed Privatdozent in Berne. In 1909 he became Professor Extraordinary at Zurich, in 1911 Professor of Theoretical Physics at Prague, returning to Zurich in the following year to fill a similar post. In 1914 he was appointed Director of the Kaiser.  As the consequence of overworking, in 1928 Einstein developed a heart disease which took him almost a year to recover from. In 1929 after his 50th birthday he built a summer house in the municipality of Caputh where he lived with his family each year between spring and late autumn until the December of 1932.

Einstein's work is also known for its influence on the philosophy of science. Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory.

Einstein always appeared to have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. He regarded his major achievements as mere stepping-stones for the next advance.At the start of his scientific work, Einstein realized the inadequacies of Newtonian mechanics and his special theory of relativity stemmed from an attempt to reconcile the laws of mechanics with the laws of the electromagnetic field. He dealt with classical problems of statistical mechanics and problems in which they were merged with quantum theory: this led to an explanation of the Brownian movement of molecules. He investigated the thermal properties of light with a low radiation density and his observations laid the foundation of the photon theory of light.Apart from all his work Einstein still found time for playing music. Since his youth he played the violin and later he frequently was seen on the street carrying his violin case. He was an admirer of Bach and Mozart and, through continuous practice, he became a good violinist. Apart from his love for music he was a devoted sailor. Doing this just for fun, here did he find the time to think about problems of physics.

His Theory of Relativity were much talked of. He received invitations and honours from all the world. There was rarely a magazine which did not report on his achievements with the highest praise. On the other hand, since 1920 Einstein and his Theory of Relativity became subject to vigorous attacks which mostly were founded on anti-Semitism. Even Nobel-prize laureates like Philipp Lenard and Johannes Stark publicly took up a hostile attitude towards Einstein and his theory and pleaded for a "German physics"

From 1909 to 1916 Albert Einstein worked on a generalization of his Special Theory of Relativity. The results of his efforts were published in March 1916 in the paper "The Foundation of the General Theory of Relativity". This theory investigates coordination systems which experience acceleration relative to each other and also the influence of gravitational fields to time and space. Whereas the Special Theory of Relativity was still intelligible to the layman, this did not apply to the General Theory of Relativity. Moreover, due to the relatively small relativistic effects, this theory was difficult to verify experimentally. Einstein - or his General Theory of Relativity - predicted the perihelion motion of mercury, the gravitational red shift as well as the deflection of light in a gravitational field. He was convinced that light deflection by the gravitational field of the sun could be observed during a total solar eclipse. After several failed observations of total solar eclipses proof came in 1919: On May 29 of that year the English astronomer Arthur Stanley Eddington confirmed Einstein's prediction of light deflection when he observed a total solar eclipse on the volcanic island of Principe in the Gulf of Guinea in western Africa. A second expedition, led by Andrew Crommelin, observed this eclipse in Sobral, Brazil.

Apart from all his work Einstein still found time for playing music. Since his youth he played the violin and later he frequently was seen on the street carrying his violin case. He was an admirer of Bach and Mozart and, through continuous practice, he became a good violinist. Apart from his love for music he was a devoted sailor. Doing this just for fun, here did he find the time to think about problems of physics.

Einstein’s fame brought him lectureships throughout the world,it also made him the focus of attacks in an increasingly anti-Semitic and militaristic Germany. Fearing for his safety, he and his wife, Elsa, immigrated to the United States on October 17, 1933, where Einstein accepted a position at the Institute for Advanced Study in New Jersey. Although some Americans opposed Einstein’s immigration for his "radical” views, Einstein embraced the opportunities and freedom of his new nation. He cowrote a famous letter to President Franklin D. Roosevelt in 1939 advising him of the possibilities of developing an atomic bomb. On June 22, 1940, Einstein took his American citizenship test and gave a talk for the government’s I Am an American radio series; he was naturalized on October 1, 1940. After World War II, Einstein advocated nuclear disarmament and international cooperation. Once in the United States, Einstein and his wife helped other Jewish refugees to emigrate to the America. Einstein expressed mixed feelings about living in the United States. He felt privileged to live in a place as peaceful as Princeton, New Jersey, but at the same time felt guilty for being able to live peacefully while so many others had lives destroyed by the war. Nevertheless, Einstein remained in Princeton until his death in 1955.

In February 1920 Einstein's mother died in Berlin. Between 1921 and 1923 he travelled, among others, to the US, Britain, France, Japan and Palestine. Since that time he began commenting on political issues more and more frequently, based on a pacifist point of view. In 1922 Einstein became member of the League of Nations' International Committee on Intellectual Cooperation which he left one year later even though he supported the aims of the League of Nations. With a revived belief in the ideals of this organisation Einstein re-joined the commission in May 1924. Opposed to any kind of violence Einstein supported pacifist movements whenever he had the chance. In addition, he supported the cause of the Zionists. He spoke up for the Hebrew University to be founded in Jerusalem to which he later also bequeathed his entire written legacy. In November 1952 Einstein even received the offer to become President of Israel which, however, he turned down.
