Charles Sheridan Swan

Charles Sheridan Swan is the man who gave his name to Swan Hunter, a major British shipbuilder.

Little is known about the early life of Charles Sheridan Swan but in 1874 he took over the management of a shipyard established in 1842 by a Mr John Coutts and by then owned by a Dr Charles Mitchell who was married to one of his (Swan's) sisters. He only managed the yard for five years as in 1879 he was killed returning from the Continent on a paddle steamer.

His widow continued the business after Swan's death in partnership with George Hunter.
