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
The question whether (and if so, to what extent) Marić contributed to Einstein's early work, and to the "Annus Mirabilis Papers" in particular, is the subject of debate. Many professional historians of physics argue that she made no significant scientific contribution, while others suggest that she was a supportive companion in science and may have helped him materially in his research. The couple's first son, Hans Albert, said that when his mother married Einstein, she gave up her scientific ambitions.
