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.
Saranac Lake, New York
Beginning in 1936, physicist Albert Einstein had a summer home in Saranac Lake, renting the cottage of local architect William L. Distin; he often sailed with his wife on Lake Flower. During World War II, Einstein summered frequently at Knollwood Club on Lower Saranac Lake. He heard with others from the radio that on August 6, 1945 the atom bomb had been dropped on Hiroshima. A few days later, Einstein gave his first interview about this event at Knollwood.
