Albert Einstein was born on March 14, 1879 in Ulm, Wurtemmburg, Germany to the parents of Hermann and Polina Kach Einstein. His parents were nonobservant Jews. One year later his family moved to Milan, Italy, but Einstein stayed in Munich. There his father ran a small factory that manufactured electrical supplies, which failed in 1894. Around 1886 Einstein began school in Munich. He attended a Munich elementary school. He didn't like to memorize facts and rules. He would answer slowly because he was a very thoughtful person. He would ask difficult questions. He was a shy and curious child. Einstein took violin lessons from age six to thirteen. He was good at mathematics and literature, but did poorly in his study areas. In his teens he was interested in popular science. Einstein didn't display his mathematics until he was 14. Einstein taught himself integral calculus and analytical geometry. In 1895 Einstein took an examination and he failed, that would had allowed him to study for a diploma as an electrical engineer at the Eidgenossische Technisch Hochschule in Zurich. Failing the entrance exam to ETH, he went to secondary school at Aurau. He was going to use to this route to enter ETH in Zurich. Einstein earned a Ph.D. in physics. Einstein married Mileva Maric a girl he knew in his student days in Zurich. They settled down in an apartment in Bern. They had two sons, but were divorced later. He married his widowed cousin Elsa in 1919. .
Einstein completed a mathematical computation that led to his 1905 report on the special theory of relativity. The theory wasn't understood because of its complicated mathematical argument. Einstein became a lecturer at the University of Bern in 1908. Einstein worked as an examiner at the Swiss Patent Office. As him being a Patent examiner he got freer time which he used to study scientific investigations. In this time he developed theories we now know in modern time.
