Albert Einstein was born at Ulm,in Württemberg, Germany, onMarch 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 Italyand Albert continued hiseducation at Aarau,Switzerland and in 1896he entered the SwissFederal PolytechnicSchool in Zurich to betrained as a teacher inphysics and mathematics
In 1901, the year he won hisdiploma, he acquired Swisscitizenship and, as he wasunable to find a teaching post,he accepted a position astechnical assistant in theSwiss Patent Office. In 1905he obtained his doctorsdegree. In 1914 he wasappointed Director of theKaiser Wilhelm PhysicalInstitute and Professor in theUniversity of Berlin.
He became a UnitedStates citizen in 1940 andretired from his post in1945.Einstein always appearedto have a clear view ofthe problems of physics.
In his early days in Berlin, Einsteinpostulated that the correctinterpretation of the special theoryof relativity must also furnish atheory of gravitation and in 1916 hepublished his paper on the generaltheory of relativity. During this timehe also contributed to the problemsof the theory of radiation andstatistical mechanics.
He contributed to statistical mechanics by his development of the quantum theory of amonatomic gas and he has also accomplished valuable work in connection withatomic transition probabilities and relativistic cosmology.After his retirement he continued to work towards the unification of the basic conceptsof physics, taking the opposite approach, geometrisation, to the majority of physicists.
Einsteins researches are, ofcourse, well chronicled and hismore important works includeSpecial Theory of Relativity(1905), Relativity , GeneralTheory of Relativity (1916),Investigations on Theory ofBrownian Movement (1926), andThe Evolution of Physics (1938).Among his non-scientific works,About Zionism (1930), Why War?(1933), My Philosophy (1934),and Out of My Later Years (1950)are perhaps the most important.
Albert Einstein received honorary doctorate degrees in science,medicine and philosophy from many European and Americanuniversities. During the 1920s he lectured in Europe, Americaand the Far East and he was awarded Fellowships orMemberships of all the leading scientific academies throughoutthe world. He gained numerous awards in recognition of hiswork, including the Copley Medal of the Royal Society ofLondon in 1925, and the Franklin Medal of the Franklin Institutein 1935.
Einsteins gifts inevitably resulted in his dwellingmuch in intellectual solitude and, for relaxation,music played an important part in his life. Hemarried Mileva Maric in 1903 and they had adaughter and two sons; their marriage wasdissolved in 1919 and in the same year he marriedhis cousin, Elsa Löwenthal, who died in 1936. Hedied on April 18, 1955 at Princeton, New Jersey.
