James Buchanan Duke (December 23, 1856 – October 10, 1925) was an American tobacco and electric power industrialist best known for the introduction of modern cigarette manufacture and marketing, and his involvement with Duke University. He was also the founder of the American Tobacco Company in 1890. Early life James Buchanan Duke, known by the nickname "Buck", was born on December 23, 1856, near Durham, North Carolina, to tobacco manufacturer, philanthropist, and benefactor of Duke University, Washington Duke (1820–1905), and his second wife, Artelia Roney. Business career Duke's father, Washington, had owned a tobacco company that his sons James and Benjamin (1855–1929) took over in the 1880s. In 1885, James Buchanan Duke acquired a license to use the first automated cigarette making machine (invented by James Albert Bonsack), and by 1890, Duke supplied 40 percent of the American cigarette market (then known as pre-rolled tobacco). In that year, Duke consolidated control of his four major competitors under one corporate entity, the American Tobacco Company, which was a monopoly as he controlled over 90 percent of the American cigarette market. His robber baron business tactics directly led to the Black Patch Tobacco Wars in 1906-1908. At the start of the 1900s, Duke tried to conquer the British market as he had done the American, eventually forcing the then divided British manufacturers to merge into the Imperial Tobacco Company of Great Britain and Ireland, Ltd (Imperial Tobacco). After two years of intense competition in Great Britain, Imperial Tobacco took the fight to the U.S. market, forcing American Tobacco to look for a settlement. This resulted in an agreement whereby American Tobacco controlled the American trade, Imperial Tobacco controlled the trade in the British territories, and a third, cooperative venture named the British-American Tobacco Company was set up between the two to control the sale of tobacco in the rest of the world. During this time, Duke was repeatedly sued by business partners and shareholders. In 1906, the American Tobacco Company was found guilty of antitrust violations, and was ordered to be split into four separate companies: American Tobacco Company, Liggett & Myers, R. J. Reynolds, and the P. Lorillard Company. In 1911, the U.S. Supreme Court upheld an order breaking up the American Tobacco Company's monopoly. The company was then divided into several smaller enterprises, of which only the British-American Tobacco Company remained in Duke's control. In 1892, the Dukes opened their
