Hans Einstein
Einstein was born in Berlin, the son of Josefa Spiero Einstein Warburg and Dr. Fritz Einstein. He spent his childhood in Hamburg, Germany as Nazism gradually took hold. His parents were Quakers, but of Jewish origin. A year after Hitler took power in 1934, his mother moved Einstein and his sister to the Netherlands, leaving his father behind. He finished high school at Eerde, a boarding school in the Netherlands at age 16 and moved to the United States as an exchange student. He attended Furman University in Greenville, South Carolina. One of the first things he did upon arriving was look up his last name in the phone book. The only Einstein he found was a relative: Albert Einstein's son, Hans Albert Einstein. They became friends and he was often invited over whenever Albert visited. He earned his medical degree from New York Medical College in 1946 and did his internship at Paterson General Hospital in Paterson, New Jersey. Following that, he became a medical officer in the United States Army. He then completed residencies in Internal Medicine and Pulmonary Diseases at the New York Veterans Hospitals.
Mileva Marić
In 1903, Marić and Einstein married in Bern, Switzerland, where Einstein had found a job at the Federal Office for Intellectual Property. In 1904 their first son, Hans Albert, was born. The Einsteins lived in Bern until 1909, when Einstein got a teaching position at the University of Zürich. In 1910, their second son Eduard was born. In 1911, they moved to Prague, where Einstein held a teaching position at the Charles University. A year later, they returned to Zurich, as Einstein had accepted a professorship at his alma mater.
