William Aiken

William Aiken Sr. (1779 – May 5, 1831) was the founder and president of the pioneering South Carolina Canal and Rail Road Company.

Born in County Antrim, Ireland, he immigrated to Charleston, South Carolina at age 10. He was raised Presbyterian. He married Henrietta Watt in 1801. They raised two children, one of whom died in infancy, while the other, William Aiken Jr., became a prominent statesman and planter. They lived at 456 King Street from 1807 until his death in 1831.

The railroad was organized in a meeting at this house in 1827, and Aiken was chosen as President. Construction of the railroad began in January 1830. He was killed in a Charleston carriage accident caused by the train's noise frightening his horse. The railroad was completed in 1833, and was the longest railroad, at 136 miles, under one management, in the world.

Aiken County, South Carolina and City of Aiken, South Carolina, industrial beneficiaries of his railroad, were named in his honor

In 2011, a statue was donated by the URS Corporation on the occasion of the City of Aiken's 175th year. The statue depicts Aiken patiently waiting, pocket watch in hand, for the next train to arrive - a symbol of the industry his railroad brought to Aiken, South Carolina.

Removal of Historical Marker In March 2025, the reference to William Aiken Sr. and the accompanying biographical information were removed from the historical marker at the Aiken County Courthouse. A new marker replaced the original attribution with a list of alternative names once considered for the county, omitting any explanation of Aiken’s role in the naming.

The old marker that was removed read, "Aiken County, created in 1871 from parts of Barnwell, Edgefield, Lexington and Orangeburg counties, was named for William Aiken, first president of the South Carolina Canal and Railroad Company. Older industries in the county today are textiles, and the mining and processing of kaolin. In 1952, the Atomic Energy Commission's Savannah River Plant began operations."

The new marker reads, "As early as the late 1820s, residents of this part of S.C. sought to create a new county due to the need for a local courthouse. Efforts were unsuccessful until the 1870-71 legislative session, when Rep. Charles D. Hayne of Barnwell District introduced a bill to create a county with the city of Aiken as its seat. Names considered for the county included Randolph, Woodbury and, finally, Aiken. On March 10, 1871, Governor Robert K. Scott signed the act creating 'Aiken County. Founded during the Reconstruction era (1865-1877), Aiken County was cut from portions of Barnwell, Lexington and Orangeburg counties. Two committees established to set the county's borders and provide for its government buildings include formerly enslaved and free-born African American men as well as white men. The first courthouse was the Gregg Mansion on Colleton Avenue. In 1872, residents elected the county's first officers and state legislators."
