Overview and metadata sections
Paul Cret was born in Lyon, France and studied at the Ecole Nationale des Beaux-Arts de Lyon and at the Ecole des Beaux-Arts, Paris. In 1903, the School of Fine Arts of the University of Pennsylvania offered him the position of Professor of Design. He was the dominant force in architectural education there until his retirement in 1937, and he had a profound impact on an entire generation of American architects. He employed many of his students in his own firm. Four of these -- John F. Harbeson, William J. H. Hough, William Henry Livingston, Sr., and Roy Frank Larson -- became full partners in the office. They continued the firm on Cret's death as Harbeson, Hough, Livingston & Larson (later renamed H2L2).
Cret had an important national practice and designed major museums, libraries, government buildings, academic buildings, monuments, bridges, and city and campus plans. In and near Philadelphia, he designed the Benjamin Franklin Parkway, the Washington Memorial Arch at Valley Forge, the Barnes Foundation, the Rodin Museum, the Benjamin Franklin Bridge, and the Federal Reserve Bank among other buildings, monuments, bridges, and planning projects.
Major projects beyond Philadelphia include the Pan American Union (Washington, DC), Indianapolis Public Library, Detroit Institute of Arts, Folger Shakespeare Library (Washington, DC), Federal Reserve Board Building (Washington, DC), University of Texas at Austin, and monuments in Europe for the American Battle Monuments Commission and the Pennsylvania Battle Monuments Commission.
Cret's archives were donated to the Library of the University of Pennsylvania by John F. Harbeson, Cret's student and colleague, and a partner in his successor firm, Harbeson, Hough, Livingston & Larson. The collection was later divided, and almost all the architectural drawings and project-related photographs were transferred to the Architectural Archives, together with a small amount of additional material. The archives, as received by the University Library, had been organized and, in many cases, annotated by Harbeson. Most of the materials transferred from the Library to the Architectural Archives had been mounted on large sheets of paperboard in groups of project-related drawings, photographs, and clippings, with annotations in Harbeson's handwriting. At the time of the transfer, the University Library retained all of Cret's correspondence, writings, and teaching files and nearly all personal materials. After Harbeson's death, the firm withdrew from its archives an additional large quantity of materials related to Cret's projects. These materials were sold to the Athenaeum of Philadelphia.
This collection is rich in Cret's sketches, renderings, and other design materials. Cret's student drawings and early competition renderings are a highlight of the collection. Of special note are renderings he made as a student in Paris, particularly "A Museum of Archaeology" and "Rendering of a Stair," and his oversized, elaborately rendered competition drawing for the Robert Fulton Memorial (with Albert Kelsey and Louis E. Jallade). These three drawings and several others in this collection were published in professional journals during Cret's lifetime.
The earliest project materials are designs for a school, made ca. 1896 while Cret was employed in the office of Louis Rogniat, in Lyon. The latest is a design for a bridge in Philadelphia in the year of his death. Projects with numerous design drawings include the Washington Memorial Arch at Valley Forge, the Detroit Institute of Arts, The Rodin Museum in Philadelphia, the Folger Shakespeare Library, the University of Texas, and a number of war memorials (including the Quentin Roosevelt Memorial and various memorials for the Pennsylvania Battle Monuments Commission and the American Battle Monuments Commission). Drawings not related to specific projects include numerous student drawings, watercolor paintings and sketches.
Although nearly all the materials of personal or biographical nature were retained by the University Library, the collection contains photographic portraits, an oil portrait (1925 by Carlo J. Ampaglia), diplomas and honors, photographs taken during World War I, watercolors by Cret's father-in-law, Oscar Lahalle (1862-1884, many made when Lahalle was an officer in the army of Emperor Maximilian), and a sketchbook (1828) and medal (1823) of Pierre Bernard (architect of Lyon, France; a member of Cret's extended family). Also useful for biographical research are Cret's sketches for interior alterations to his own residence in Philadelphia (1913, 1920) and Cret's watercolor sketches made in France.
Additional materials acquired by the Architectural Archives from other sources include construction prints of Cret's Chemistry Building for the University of Pennsylvania, construction prints of the Pan American Union (with Albert Kelsey) and construction prints of the Hartford County Building. None of these constitutes a complete set. The collection contains no office files.
This collection is arranged into 5 series as follows:
- Series I. Project Materials
- Series II. Memorabilia
- Series III. Cret Sketchbooks and Unmounted Small Drawings
- Series IV. Three-Dimensional Objects
- Series V. Oversize
Gifts of John F. Harbeson to the Library of the University of Pennsylvania, 1965-1978. Materials were transferred to the Architectural Archives from 1978 to 1980. Additional materials transferred from the University of Pennsylvania, Division of Facilities Services. Additional materials gift of the Library of Congress, 1993. Additional drawings related to the design of the Rodin Museum were gifted to the Archives by Melissa Krieder in 2024 and Georgia Marsh in 2022.
The collection was processed and the finding aid prepared by William Whitaker, Emily Cooperman, Laura Stroffolino and Nancy Thorne with the assistance of Jane E. Dorchester. Additional assistance was provided by Gregory Vigo-Torres, Jennifer Webb, Lisa Boettger, Shillest Clayton, Julie Dunn, Charles McGloughlin and Matthew Pisarski. Work was substantially completed in 2001, with additions and corrections in 2003. Finding aid was updated in June 2026 to include recently accessioned materials related to the Rodin Museum (see accessions 2022-12 and 2024-09)
Finding aid was updated to current archival description standards and was migrated into ArchivesSpace by Courtney Smerz, Head Archivist in June 2026.

Collection Inventory
Series I combines drawings, photographs, and clippings in one series. Most of the materials in this series were arranged, mounted on paperboard, and annotated by John Harbeson for study and exhibition. Harbeson wrote numbers on these materials corresponding to job numbers, even though many "jobs" so identified were not products of Cret's architectural practice. Harbeson's comments in his typescript job list, "The Architectural Work of Paul Philippe Cret, 1876-1945" provide useful information about the numbering system:
Previous to 1920 the office had been conducted from Paul Cret's house, 516 Woodland Terrace. In 1920 numbers under 100 were assigned to the jobs done at Woodland Terrace, but these are not strictly arranged in proper date sequence. . . . For convenience the earliest numbers have been assigned to Cret's student projects, to early studies and sketches, to architectural work performed in France, before he came to this country in 1903, and to minor compositions such as book-plates, seals, medals, title pages, small memorials and to early architectural projects in this country. . . . When work was done for a client on more than one occassion [sic] even though a new contract number was assigned the records were, for facility or [sic] consultation, later filed under the earlier job number - thus many of the trains designed for the Budd Company became ultimately all 278 with a, b, c, etc., down to zz, and the forty or more tablets for the Pennsylvania Historical Commission all became 180, etc.
In Series I, materials are arranged by job numbers found in Harbeson's annotations. Materials lacking a label or annotation (including materials acquired from other sources) have been interfiled with labeled materials using numbers from Harbeson's job list.
See 062.82 for additional watercolor sketches by Colonel Lahalle.
Series II. Memorabilia includes diplomas, honors and photographic portraits of Cret, as well as drawings by others which Cret kept. These drawings include, for example, watercolors by his father-in-law, Oscar Lahalle, a sketchbook of Pierre Bernard, a watercolor by Boris I. Riaboff and caricatures of Cret and others by Alfred Bendiner.
Series III. Cret Sketchbooks and Unmounted Small Drawings includes only drawings by Cret.
Series IV. Three-Dimensional Objects includes medals designed by Cret and medals awarded to Cret. Of particular interest are two plaster models of Cret's medal designs (Alfred Bottiau and A. Pietz, sculptors) and examples of the completed medals.
