Early life and career

main: Early life and career of Barack Obama

Barack Obama was born on August 4, 1961, in Honolulu, Hawaii, to Barack Obama, Sr., a black Kenyan of Nyang'oma Kogelo, Siaya District, Kenya, and Ann Dunham, a White American from Wichita, Kansas. His parents met while attending the University of Hawaii at Manoa, where his father was a foreign student. They separated when he was two years old and later divorced. Obama's father returned to Kenya and saw his son only once more before dying in an automobile accident in 1982. After her divorce, Dunham married Lolo Soetoro, and the family moved to Soetoro's home country of Indonesia in 1967, where Obama attended local schools in Jakarta until he was ten years old. He then returned to Honolulu to live with his maternal grandparents while attending Punahou School from the fifth grade in 1971 until his graduation from high school in 1979. Obama's mother returned to Hawaii in 1972 for several years and then back to Indonesia for her fieldwork. She died of ovarian cancer in 1995. As an adult Obama admitted that during high school he used marijuana, cocaine, and alcohol, which he described at the 2008 Civil Forum on the Presidency as his greatest moral failure.
