Leighton Orr graduated from the University of Pittsburgh with a bachelor's degree in mechanical engineering in 1928. Following graduation, he experimented with heat loss through glass block walls and double glazed windows. After working for six years at the Pittsburgh Testing Laboratory, he went to the Pittsburgh Plate Glass Company Research Laboratory in Pittsburgh, where he managed the physical testing department. Pittsburgh Plate Glass Company would change its name to PPG Industries, Inc., in 1968. Here he experimented with optics, heat flow, strength, safety, impact performance, and rating degree of anneal and temper in glass products; in addition he researched glass quality, types of defects, fracture analysis, selection of glass sizes, and thicknesses for wind loads on monolithic and insulating glass products; also receiving attention were issues of water loads on multiple laminated windows aquaria. Orr provided guidance to government agencies on the development of glass testing standards and fracture analysis of glass.

He retired from PPG Industries in 1972, but had a prolific career as a technical glass and ceramics consultant, in which he completed approximately 950 reports for clients as varied as architects, insurance companies, building owners, glass companies, developers and lawyers. Orr was sought out for his expertise in fracture analysis and breakage by high profile clients such as I. M. Pei and Partners, contributing work to Boston's John Hancock Center.

Orr was a member of the American Society of Mechanical Engineers (ASME) for over 60 years, where he received the distinction of being a Life Fellow. The University of Pittsburgh, School of Engineering made him a Distinguished Alumni in 1997, and placed him in the School of Engineering Hall of Fame.

Orr was 97 years old when he passed away on April 21, 2004 at the Concordia Retirement Home in Cabot, Pa. He had been busy doing consulting work until February, 2004. ASME established the Leighton E. and Margaret W. Orr Award for contributions to the literature on fractures and failure investigations as part of the considerable endowment Orr left them.

Collection Scope and Content Notes

This collection contains the reports generated by Leighton E. Orr in the course of his work as a technical glass and ceramics consultant between 1968 and 2003. Orr lent his expertise to a variety of projects, large and small, throughout the United States and Canada. Over the course of his consulting career, he worked for such notable clients as I. M. Pei and Partners, Roche Dinkeloo, the Metropolitan Museum of Art, the Disney Corporation, Thermos and the Architect's Collaborative, generating approximately 950 reports.

These reports feature summaries, technical drawings and photographs. The collection preserves Orr's original order which is generally a chronologically organized number scheme, with certain folders dedicated to individual clients. Each folder contains a range of reports, with the specific clients and projects being named in the folder scope content notes, which are inventories directly based upon Orr's index found in Box 1, Folder 01. In many cases Orr employed idiosyncratic spellings and abbreviations in his index, while the actual reports tended towards accuracy in these matters. When possible, to facilitate keyword searching, misspelled names and odd abbreviations were normalized in the scope notes which follow. For those desiring to see the Orr’s original terminology, it is available in the previously mentioned index. Approximately 87 of the 950 jobs that are described in the index sheets of Box 1, Folder 01 do not have corresponding reports. In some cases Orr has inserted a handwritten note into the report sequence to clarify the omission. The materials in this collection date from September 9, 1968 to May 10, 2003.


The arrangement for the Leighton E. Orr Collection has been maintained in its original form, which is generally chronological with several minor deviations. That is, reports correspond to the inventory designed and implemented by Orr.
