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. This is based on the legal concept known as air rights. He is also credited with the double-stacked track design of the station, that greatly increased its capacity. During the First World War, Wilgus served as the American Expeditionary Force chief of logistics and rail transport. Provided by Wikipedia
