Ellsberg was born in Chicago, Illinois, on April 7, 1931, the son of Harry and Adele (Charsky) Ellsberg. His parents were Ashkenazi Jews who had converted to Christian Science, and he was raised as a Christian Scientist. In 2008, Ellsberg told a journalist that his parents considered the family Jewish, "but not in religion."[2]
Ellsberg grew up in Detroit and attended the Cranbrook School in nearby Bloomfield Hills. His mother wanted him to be a concert pianist, but he stopped playing in July 1948, two years after both his mother and sister were killed when his father fell asleep at the wheel and crashed the family car into a bridge abutment.[3]
Ellsberg entered Harvard College on a scholarship, graduating summa cum laude with an A.B. in economics in 1952. He studied at King's College, Cambridge, for a year through funding from the Woodrow Wilson National Fellowship Foundation, initially for a diploma in economics and then changed his credits toward a PhD in the subject, before returning to Harvard.[4] In 1954, he enlisted in the United States Marine Corps and earned a commission.[5] He served as a platoon leader and company commander in the 2nd Marine Division, and was discharged in 1957 as a first lieutenant.[5] Ellsberg returned to Harvard as a Junior Fellow in the Society of Fellows for two years.[5]
