The Gulf Tower is one of those buildings of the style old Pa Pitt calls “Mausoleum-on-a-stick,” where a skyscraper ends in a top modeled after the Mausoleum at Halicarnassus. Trowbridge and Livingston, who designed the Gulf Tower (with Edward Mellon as local architect of record), were the originators of the style, as far as Father Pitt can determine: the Gulf Tower is a Moderne reimagining of their original Mausoleum-on-a-Stick, the Bankers Trust Company Building on Wall Street, New York.
An Art Deco interpretation of the skyscraper style old Pa Pitt calls “Mausoleum-on-a-Stick,” in which the cap of the skyscraper is patterned after the Mausoleum at Halicarnassus. The architects, York & Sawyer, seem to have been taken with the style; they designed another Mausoleum-on-a-Stick building in the same year (1926) for Montreal. You can see a picture of it in one of old Pa Pitt’s earlier articles on Allegheny General Hospital.
The original skyscraper hospital was a marvel of practical hospital design. Everything radiates from a central core of elevators, and nothing is more than a few steps from the elevator. Later the hospital was expanded with new buildings in wildly mismatched styles, so that the complex has become the hopeless jungle of dead-end corridors and mismatched floors usual in big-city hospitals.
