William Smith Fraser (1852–1897) was an American architect based in Pittsburgh, Pennsylvania. Fraser is best known for his designs for the Herron Hill Pumping Station (1896), a City of Pittsburgh Historic Structure, and the original Joseph Horne Company Department Store (1893), a Pittsburgh History and Landmarks Foundation Historic Landmark, though substantially rebuilt by later architects.

The Joseph Horne Company, often referred to simply as Joseph Horne's or Horne's, was an American department store chain based in Pittsburgh, Pennsylvania. The store was one of the oldest in the country being founded on February 22, 1849, but was often overlooked as it maintained only a regional presence. The chain ceased operations in 1994 after being merged with the Lazarus division of Federated Department Stores.
