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
In 1944, Robert Einstein, who had lived in Italy for many decades, resided with his family in Rignano sull’Arno, southeast of Florence, in the Villa Tenuta dell Focardo. His family consisted of Caesarina, his wife, the daughter of a Protestant minister, his two daughters Luce and Cici, 27 and 18 years old respectively, and his adopted nieces Lorenza and Paola Mazzetti, who were the 17-year-old twin daughters of his late sister-in-law.
