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).
Political views of Albert Einstein
Albert Einstein was widely known during his lifetime for his work with the theory of relativity and physics in general. He was also an important peace activist, a world federalist and a socialist. His political opinions were of public interest through the middle of the 20th century due to his fame and involvement in political, humanitarian and academic projects around the world. He was often called upon to give judgments and opinions on matters often unrelated to theoretical physics or mathematics. Einstein's visible position in society allowed him to speak and write frankly, even provocatively, at a time when many people were silenced due to the rise of the Nazi movement.
