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.
Murder of the family of Robert Einstein
The murder of the family of Robert Einstein, a cousin of Nobel Prize Laureate Albert Einstein, took place on 3 August 1944 in Rignano sull'Arno, Italy, during World War II. Shortly before their withdrawal from the area, German soldiers arrived at the Einstein residence, executed Robert's wife and two daughters, and set the house on fire. Robert, who was in hiding at the time, survived the events but committed suicide less than a year later, on 13 July 1945.
