Technology, Capital, and Consolidation: The Performance of De Beers Mining Company Limited, 1880–1889

In this article, Dr. Newbury focuses on the technical and financial reasons for amalgamation at the Kimberley mines in South Africa, drawing on primary records to account for the rise of De Beers as the world's major diamond mining company in the 1880s. He finds that prior experience in local government and on the mining boards prepared company directors for competition in joint stock enterprise, while differences in production policies and performance influenced the pattern of mergers within and among the four Kimberley mines. De Beers's close relationship with diamond merchants and private banks in London, particularly N. M. Rothschild & Sons, was central to its position as a prime mover toward consolidation. Dr. Newbury views De Beers as a firm that relied for its success less on its renowned chairman, Cecil J. Rhodes, than on a combined managerial expertise that reflected the interests of both mining producers and merchant buyers.
