Hans Albert Einstein
Hans Albert Einstein was born on May 14, 1904 in Bern, Switzerland, where his father, Albert Einstein, worked as a clerk in the patent office. His father was of German-Jewish descent and his mother, Mileva Marić, Serbian-Orthodox. His younger brother, Eduard Einstein, was born in 1910 and died in 1965. The fate of his older sister, Lieserl Einstein, Albert Einstein's and Mileva Marić's first child, is unknown. Their parents divorced in 1919 after living apart for five years.
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.
