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.

Throughout his life, Einstein published hundreds of books and articles. He published more than 300 scientific papers and 150 non-scientific ones. On 5 December 2014, universities and archives announced the release of Einstein's papers, comprising more than 30,000 unique documents. Einstein's intellectual achievements and originality have made the word "Einstein" synonymous with "genius."
