Trowbridge & Livingston were a New York firm favored by Andrew Mellon. It was originally a partnership between Breck Trowbridge (Samuel Breck Parkman Trowbridge on his birth certificate) and Goodhue Livingston; but Trowbridge died in 1925. Of the three main buildings the firm supervised here, two were therefore under the direction of Livingston alone.
The Mellon National Bank Building, 1923.
The Gulf Building (now Gulf Tower, because every Building became a Tower while you weren’t looking), 1932. This was Pittsburgh’s tallest skyscraper for four decades, and we have put together a timeline of the Gulf building from the rumor stage to completed and filling up with tenants. The associate architect on this project was E. P. Mellon, Andrew’s nephew.
The United States Post Office and Courthouse, 1935.
