Founded in 1913 by noted bankers and brother Andrew W. Mellon (1855-1937) and Richard B. Mellon (1855-1932),
this building housed an institution that was a forerunner of what is now Carnegie-Mellon University.
Designed by architect Benno Janssen (1874–1964), the building is noted for its neo-classical architecture and its signature monolithic limestone columns which are the largest in the world. This facade has often been used as a location by visiting filmmakers.
Today this magnificent building houses various Carnegie-Mellon University science departments. The 150-seat auditorium is sometimes used for events by outside groups.
The offices are open Monday through Friday, 8:00 a.m. to 5:00 p.m.
Parking is available nearby in a garage on Dithridge Street, which connects with Fifth Avenue.
