He "rose above humble beginnings to become the most successful and most recognizable black entrepreneur in the history of the petroleum industry." As an internationally known oil broker he partnered with Phillips Petroleum Company and Signal Oil and Gas Company to open up African oil fields in Liberia, Nigeria and Ghana. In 1969, he became the first black person to be appointed to the National Petroleum Council.
