Anglo American has its roots in South Africa, founded in 1917 by Sir Ernest Oppenheimer as the Anglo American Corporation, with the initial financial backing from UK and US sources providing the Anglo and the American to the company name.
Nine years later, in 1926, the corporation becomes the largest single shareholder in diamond company De Beers, and Oppenheimer becomes chairman of the diamond producer shortly after. Anglo American today owns 85% of De Beers, with the remaining stake held by the Government of Botswana.
