William Hunter Dammond was an American civil engineer. He studied civil engineering at the Western University of Pennsylvania and, in 1893, was the first African American to graduate from that institution. As a black man Dammond found it difficult to secure employment as an engineer and, after a number of different roles, in 1897 found work as a professor at Paul Quinn College in Waco, Texas. From 1899 Dammond taught at Wilberforce University in Ohio but left to join the Michigan Central Railroad (MCR) in the early 1900s. At MCR he developed the Dammond circuit, a means of providing signals in drivers' cabs. In 1906 he developed a traffic light-like system for signalling. In 1910 Dammond moved to Britain to promote his signalling systems. Despite an extensive period of testing he was unsuccessful in selling it and found work as a bridge designer with Marcum Company.
