Barack Hussein Obama Sr. (/ˈbærək huːˈseɪn oʊˈbɑːmə/; 18 June 1934 – 24 November 1982) was a Kenyan senior governmental economist and the father of Barack Obama, the 44th president of the United States. He is a central figure of his son’s memoir, Dreams from My Father (1995). Obama married in 1954 and had two children with his first wife, Kezia. He was selected for a special program to attend college in the United States and studied at the University of Hawaii where he met Stanley Ann Dunham, whom he married in 1961. They had a son, Barack II. Dunham divorced Obama three years later. The elder Obama later went to Harvard University for graduate school, where he earned an M.A. in economics, and returned to Kenya in 1964. He saw his son Barack once more, when he was about 10.
In late 1964, Obama Sr. married Ruth Beatrice Baker, a Jewish-American woman he had met in Massachusetts. They had two sons together before separating in 1971 and divorcing in 1973. Obama first worked for an oil company, before beginning work as an economist with the Kenyan Ministry of Transport. He gained a promotion to senior economic analyst in the Ministry of Finance. He was among a cadre of young Kenyan men who had been educated in the West in a program supported by Tom Mboya. Obama Sr. had conflicts with Kenyan president Jomo Kenyatta, which adversely affected his career. He was fired and blacklisted in Kenya, finding it nearly impossible to get a job. Obama Sr. was involved in three serious car accidents during his final years; he died as a result of the last one in 1982. (Source)
