Collection Type:


Tasso Katselas is Pittsburgh's leading modern architect. He established his practice in 1955, and has produced a steady stream of significant buildings in Pittsburgh and western Pennsylvania up to the present day. These include most notably the St. Vincent Monastery (1967) and St. Vincent College Science Center (1969), both at Latrobe, the Community College of Allegheny County in Pittsburgh (1973), the Carnegie Science Center (1991), and the Greater Pittsburgh International Airport (1992). He has designed a full range of building types, but has a specialization in airport design.

Katselas has designed many large buildings on prominent sites, particularly in the Oakland district of Pittsburgh, and many projects for the Allegheny County government. The prominence of these projects has made him a lightning rod for both acclaim and criticism. Less well known is the extensive small-scale work that he has designed and often contributed to neighborhoods and community organizations; and his residential work, including the early Katselas house, which has been featured in architectural guidebooks as an example of "brutalist" domestic design.

Scope and Content: 

The collection includes preliminary and/or working drawings for key projects including the Katselas house, St. Vincent Monastery, St. Vincent College Science Center, the Community College of Allegheny County, and East Hills Elementary School. Also included are reports and publications documenting the Greater Pittsburgh International Airport; a 1975 proposal for the Bagdad International Airport; and a 1996 competition entry for the Kansai-Kan National Diet Library in Japan.
