The Keystone Athletic Club was designed by Benno Janssen, Pittsburgh’s favorite architect for high-class clubs of all sorts. Most of them were classical in style, but for this skyscraper clubhouse Janssen chose a simple and streamlined Gothic style instead. It is now Lawrence Hall, the main building of Point Park University, so that two universities in Pittsburgh have trademark Gothic skyscrapers.
Early in his career, Benno Janssen was a fiend for terra cotta; he was much more restrained later on, but he usually included some characteristically appropriate terra-cotta ornaments.
