Cret was a naturalized U.S. citizen who had trained at the in
Lyon and
Paris. He was invited to the United States in 1903 to establish the department of architecture at the
University of Pennsylvania, and established his own practice in 1907. His first major commission was the
Pan American Union Building, in Washington, D.C. (1908). Designed with
Albert Kelsey, it was a building in quintessential
Beaux-Arts style, with a classical
façade, rich ornamentation, and allegorical references to the goals of the organization. This led to many other commissions for war memorials, civic buildings, court houses, and museums in cities such as
Detroit,
Hartford,
Philadelphia,
Indianapolis, and Washington, D.C. By 1935, under the influence of Modernism, Cret's style had evolved toward the
Stripped Classicism of buildings such as the
Folger Shakespeare Library (1929–32). But true to the Beaux-Arts tradition, he oversaw every aspect of the building project, including technical and aesthetic details. His firm made more than 300 freehand sketches, measured plans, site plans, elevational studies, and perspective drawings, each of which could contain front, side, and top views, and sectional details when necessary. is in the shape of the letter
H, with the space on either side of the building's center forming east and west courtyards. The interior has a two-story atrium with dual staircases and a skylight etched with the outline of an eagle. The atrium floor is of marble and its walls are of
travertine marble. The largest meeting space is the two-story Board Room. Construction of the building began in 1935 and was completed in 1937. Its pragmatic classicism captured the spirit of Depression-era and wartime Washington, a city determined to remain grand but with nothing to spare on the non-essential. ==Ornamentation and furnishings==
