Henri Wilhelm August Deterding, KBE (19 April 1866 – 4 February 1939) was one of the first executives of the Royal Dutch Petroleum Company and was its general manager for 36 years, from 1900 to 1936, and was also chairman of the combined Royal Dutch/Shell oil company. He succeeded the founder of Royal Dutch, Jean Baptiste August Kessler, when he died, and made Royal Dutch Shell a competitor to John D. Rockefeller's Standard Oil and one of the world's largest petroleum companies. In 1920, Deterding was made an honorary Knight Commander of the Order of the British Empire, for services to Anglo-Dutch relations and for his work in supplying the Allies with petroleum during the First World War. Deterding was a bitter enemy of the Soviet Union and helped thousands of White Russian exiles. Early life Born in Amsterdam in 1866, the fourth child in a family of five, Deterding was the son of Philip Jacob Deterding, a merchant navy master mariner, and Catherina Adolphina Geertruida ( Kayser). However, Henri was educated up to the age of sixteen at the Higher Citizens' School in Amsterdam. Career After leaving school, Deterding took a clerical position in the Twentsche Bank, where he developed a remarkable aptitude for handling figures. To avoid the slow promotion of a banking career, he entered an examination for positions in the Netherlands Trading Society of the Dutch East Indies, gained first place, and was appointed to the company's Eastern staff. After some years with the firm, he began to work in the oil industry, which was then in its infancy. In May 1896, at the age of thirty, Deterding took a job with the Royal Dutch Oil Company, working with the managing director, J. B. A. Kessler. At the time, Royal Dutch was not a major company, still struggling to make good, and Deterding was instrumental in piloting it through many difficulties. Kessler died in March, 1900, leaving instructions, put in writing shortly before his death, that he wished Deterding to take over from him as general manager. Soon gaining the nickname of "the Napoleon of Oil", Deterding was responsible for developing the tanker fleet that enabled Royal Dutch to compete with the Shell company of Marcus Samuel. He led Royal Dutch to several major mergers and acquisitions, including the merger with Samuel's "Shell" Transport and Trading Company in 1907 and the purchase of Azerbaijan oil fields
