Thomas Martin Einstein
Albert Einstein had three children, Lieserl Maric (1902–1903?), Hans Albert Einstein (1904–1973), and Eduard "Tete" Einstein (1910–1965), but only Hans Albert is known to have married and had children. Hans Albert's only biological child to survive to adulthood was Bernard Caesar Einstein (1930–2008), who was a physicist and the father of Thomas Martin Einstein.
Emil Grosswald
He met his wife Elisabeth (Lissy) Rosenthal in Cuba, probably in 1941 or 1942. They were married in 1950 in Saskatoon, Canada, where he had his first teaching position after receiving his Ph.D. They spent two years at the Institute for Advanced Studies in Princeton, New Jersey in 1951 and 1959. During their first stay, they met Albert Einstein, with whom Emil had a correspondence, later bequeathed to the University of Texas, and formed many friendships, among others with the physicist Freeman Dyson. Emil and Lissy had two daughters, Blanche, who became a professor of Social Work at Rutgers University but died in 2003 at the age of 50, and Vivian, a professor of law at the University of Pittsburgh. Vivian was decorated in 2007 by the Republic of Austria for her work as the United States appointee to the Austrian General Settlement Fund Committee for Nazi-era property compensation, and in 2013 by the government of France for her services in promotion of the French language and culture in the United States. Emil is the uncle of Pamela Ronald, whose father Robert Ronald (né Rosenthal) describes the family’s escape from the Nazis in his memoir, The son of Lissy’s second cousin (Ernest Beutler) is 2011 Nobel Laureate Bruce Beutler. Emil was also the nephew of the French musician Marcel Mihalovici, who arrived in Paris in the 1920s with George Enescu.
