The Pittsburgh Athletic Association, built in 1911, is Pittsburgh’s grandest clubhouse. (Not the richest, of course: that honor belongs to the Duquesne Club, the focus of all money and power in the city.) The architect was Benno Janssen, who was quite successful in Pittsburgh in the early 1900s. The club itself went bankrupt in 2017, but was able to make a deal to sell the building to investors who will allow them to occupy part of it. Now the building is getting a renovation.
