James Buchanan Duke, known as "Buck" Duke, was an American tobacco and electric power industrialist best known for his involvement in the growth of the American tobacco industry and his pivotal role in establishing the Duke Power Company, the precursor to Duke Energy.
Born on December 23, 1856, in Durham, North Carolina, Duke grew up in the post-Civil War South. His father, Washington Duke, had a small landholding and grew tobacco, setting the stage for Duke's future success.
