William J. Wilgus

William J. Wilgus (1865–1949) was an American civil engineer. In 1902 he was responsible for the design and construction of New York City's Grand Central Terminal. Wilgus coined the term "taking wealth from the air" from his idea to lease the area above the Park Avenue Tunnel in order to help finance the station. He is also credited with the double-stacked track design of the station, that greatly increased its capacity.
