William Barclay Parsons

An American civil engineer born in New York on April 15, 1859, he graduated from Columbia College and the Columbia School of Mines before building a distinguished career in transportation and infrastructure. He became especially prominent for his work on the planning and construction of New York City’s original subway system, a project that helped define his reputation.

His career reached well beyond New York. He worked on railroad and transit projects in the United States and abroad, and he also served in the U.S. Army during the Spanish-American War and later in World War I. That mix of engineering and national service made him a notable public figure in his field.

He died on May 9, 1932. Remembered as both a builder and an organizer, he belonged to the generation of engineers who helped turn rapidly growing cities into modern urban systems.
