Clapp Hall

File:Clapp Hall, University of Pittsburgh, 2023-08-21, Tennyson Avenue side 01.jpg

Clapp Hall was designed by Trautwein & Howard, a successor to architectural firm of Charles Klauder who designed the university's gothic Cathedral of Learning, Stephen Foster Memorial, and Heinz Memorial Chapel.

Clapp Hall's exterior and interior spaces have been described as a mix of Collegiate Gothic and Art Deco. The building features a diagonally-positioned entrance that creates a direct axis with the Cathedral of Learning which is framed in Clapp Hall's stone portal entryway. The building is clad in textured Indiana limestone to match the stone used on the Cathedral of Learning. The building's use of aluminum windows has been suggested to be a quiet homage to the work of aluminum magnate George Hubbard Clapp, the building's namesake. The lobby of Clapp Hall is streamlined Art Deco in character, with terrazzo flooring and stainless steel doors, and is thus more stylistically modern than its exterior which is meant to reflect the Cathedral of Learning. It has been suggested that the lobby reveals a struggle in the design process to find a balance between the traditional gothic and more contemporary design elements.{{citation | url=http://www.pfaffmann.com/documents/PittCivicCenterConservation%20Plan_2006.pdf | title=University of Pittsburgh Civic Center Conservation Plan | date=September 2005 | page=173 | last=Pfaffmann | first=Rob | publisher=Pfaffmann + Associates, PC and the Getty Foundation Campus Heritage Program | access-date=2010-01-27}}

Original plans slated Clapp Hall to be built adjacent to the Cathedral of Learning facing the Masonic Temple, on the south side of Fifth Avenue, between the Cathedral and Heinz Memorial Chapel. Concerns over adding more buildings to the Cathedral of Learning lawn and impinging on the lawn's rare open space prompted a change to its current site across Fifth Avenue and effectively ended above-ground development of the Cathedral lawn space.{{Cite web|url=http://digital.library.pitt.edu/cgi-bin/t/text/pageviewer-idx?c=pittmiscpubs;cc=pittmiscpubs;q1=Clapp%20Hall;rgn=full%20text;idno=00c50130m;didno=00c50130m;view=image;seq=220;page=root;size=s;frm=frameset;|title = }}

The triangular courtyard at the southwest entry to Clapp Hall, facing the Cathedral of Learning, was modified in 2004 to accommodate trees and benches.

The building is named for George Hubbard Clapp (1858–1949), an alumnus (class of 1877) and president of Pitt's board of trustees for more than 40 years. Clapp was one of five responsible for the first commercial production of aluminum and was a founder of the Aluminum Company of America.{{cite web |url=http://www.pitt.edu/~biohome/Dept/Frame/clapphall.htm |title=Clapp Hall |website=www.pitt.edu |url-status=dead |archive-url=https://web.archive.org/web/20000517201553/http://www.pitt.edu/~biohome/Dept/Frame/clapphall.htm |archive-date=2000-05-17}}

The six-story structure contains laboratories, classrooms, and an amphitheater-style lecture hall with 404 seats. A greenhouse, used mostly for teaching, is located on the fourth floor of Clapp Hall. Clapp Hall originally housed Pitt's Departments of Physics, Chemistry, Biology, Metallurgy, and Chemical Engineering.[http://images.library.pitt.edu/cgi-bin/i/image/image-idx?xc=1;g=imls;sid=f3e36cbef4eb6bab58c122aaec63ff65;q1=oakland;rgn1=dc_su;size=20;lasttype=boolean;view=entry;lastview=thumbnail;subview=detail;cc=accd;entryid=x-msp285.b004.f13.i19;viewid=ACCD0210.TIF;start=21;resnum=36] Today the Department of Biological Sciences occupies the building.
