Elizabeth Roboz Einstein
Roboz married Hans Albert Einstein, first son of physicist Albert Einstein, and professor of hydraulic engineering at the University of California, Berkeley, in June 1959. They did not have any children together, although Hans had four children from his first marriage to Frieda Knecht, only two of whom survived into adulthood. Hans died on July 26, 1973, and Roboz wrote a biography of him, "Hans Albert Einstein: Reminiscences of his Life and our Life Together" (1992).
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.
