1875 Henry A. du Pont
Henry Algernon du Pont graduated first in his class at West Point in 1861 and served as a light artillery officer during the Civil War, reaching the rank of lieutenant colonel at age 26. "Colonel Henry" stayed with the military for 10 years, and then resigned his commission in 1875 to return to Delaware. He managed shipping for DuPont and served as president of the Wilmington & Northern Railroad from 1879 to 1889.

When "General" Henry died in August 1889, it was assumed that one of his sons, either Henry Francis or his brother William, would take control of the business, but conflict between the two led to the accession of Eugene du Pont as a compromise. Henry was offered the position of president when Eugene died in 1902. He refused, however, due to his age and his desire to run for the United States Senate. When no senior partner was willing to take control, Henry supported the sale of the company to the younger generation of du Ponts and helped convince the senior partners to accept it. After serving in the U.S. Senate, he spent his remaining years writing at his Winterthur estate.
