Collis Potter Huntington (October 22, 1821 – August 13, 1900) was an American industrialist and railway magnate. He was one of the Big Four of western railroading (along with Leland Stanford, Mark Hopkins, and Charles Crocker) who invested in Theodore Judah's idea to build the Central Pacific Railroad as part of the first U.S. transcontinental railroad. Huntington helped lead and develop other major interstate lines, such as the Southern Pacific Railroad and the Chesapeake & Ohio Railway (C&O), which he was recruited to help complete. The C&O, completed in 1873, fulfilled a long-held dream of Virginians of a rail link from the James River at Richmond to the Ohio River Valley. The new railroad facilities adjacent to the river there resulted in expansion of the former small town of Guyandotte, West Virginia, into part of a new city which was named Huntington in his honor.
Turning attention to the eastern end of the line at Richmond, Huntington directed the C&O's Peninsula Extension in 1881–82, which opened a pathway for West Virginia bituminous coal to reach new coal piers on the harbor of Hampton Roads for export shipping.
