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).
Murder of the family of Robert Einstein
On 3 August a group of German soldiers arrived at the villa in search of Einstein. When he was not to be found the soldiers began vandalising the place and interrogated the women individually. The soldiers conducted an ad-hoc tribunal and then shot Einstein's wife and daughters in the garden. His nieces remained locked in the upper part of the house, guarded by a young German soldier who had refused to participate in the murders and was visibly shaken by the events. After the murders the two surviving girls were locked in a shed and the villa itself set on fire.
