Einstein was born at Ulm in Württemberg, Germany on March 18, 1879. His family wasJewish but was not very religious. Albert did not talk until he was about three, which is very unusual.[needs proof] When Albert was around four, his father gave him a magnetic compass. He tried hard to understand how the needle could seem to move itself so that it always pointed north. The needle was in a closed case, so clearly nothing like wind could be pushing the needle around, and yet it moved. So in this way Einstein became interested in studying science and mathematics. His compass inspired him to explore the world. Albert went to a Roman Catholic school. He was not a good student, and many people thought him to not be very smart.
When he became older, he went to a school in Switzerland. After he graduated, he got a job in the patent office there. While he was working there, he wrote the papers that made him famous as a great scientist.Einstein had two heavily-disabled children with his first wife Mileva His daughter 'Lieserl' (her real name may never be known) was born about a year before their marriage in January 1902.[3] She spent her very short life (believed to be less than 2 years) in the care of Serbiangrandparents where it is believed she died from Scarlet Fever.[4] Some believe she may have been born with the disorder called Down syndrome but it has never been proven. Her very existence only became known to the world in 1986 when a shoe-box, containing 54 love letters (mostly from Einstein) exchanged between Mileva and Einstein from late 1897 to September 1903, was discovered by Einstein's grand-daughter in an attic in California.[5] Their son, Eduard, was diagnosed at age 7 with a severe mental illness. He spent decades in hospitals, and died in the Zurich sanatorium in 1965.
There is an indirect connection between brain size and the size of the neopallium especially important for the brain's higher functions. However, Einstein's brain weight was below-average and showed signs of degeneration (e.g. Sylvian fissure).
In 1917, Einstein became very sick with an illness that almost killed him. It was his cousin Elsa Lowenthal who nursed him back to health. After this turn of events, Einstein divorced Mileva, and married Elsa on June 2, 1919.
Just before the start of World War I, he moved back to Germany, and became director of a school there. He lived in Berlin until the Nazigovernment came to power. The Nazis hated people who were Jewish or who came from Jewish families. They accused Einstein of helping to create "Jewish physics," and German physicists tried to prove that his theories were wrong.
In 1933, under death threats from the Nazis and despised by the Nazi-controlled German Press, Einstein and Elsa moved to the United States to Princeton, New Jersey after feeling the heat of Nazi Germany and in 1940 he became a United States citizen.
During World War II, Einstein and Leó Szilárd wrote to the U.S. president Franklin D. Roosevelt, to say that the United States should invent an atomic bomb before the Nazi government could invent one first. He was not part of the Manhattan project, which was the project to create the atomic bomb. He was the only one that signed the letter.
Einstein died on 18 April 1955 of a burst aorta heart disease. He was still writing about quantum physics hours before he died.
