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).
Legitimacy (family law)
Nonmarital birth has affected not only the individuals themselves. The stress that such circumstances of birth once regularly visited upon families, is illustrated in the case of Albert Einstein and his wife-to-be, Mileva Marić, who—when she became pregnant with the first of their three children, Lieserl—felt compelled to maintain separate domiciles in different cities.
