With degrees from various institutions including New York University School of Law, Harvard Law School, and a doctorate from the University of Exeter, Yamani became a close adviser to the Saudi government in 1958 and then became oil minister in 1962. He is best known for his role during the 1973 oil embargo, when he spurred OPEC to quadruple the price of crude oil. During that time, Yamani gained a colourful international reputation, known in the West for both diplomatic skills and his characteristic goatee.
