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 an impressive 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. The four-story building, with an exterior of Georgia marble, 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 Cret employed nationally recognized artists to complete the ornamentation and furnishing of the building. Sidney Waugh designed the eagle on the front facade, the building's only three-dimensional sculpture which was carved by the Piccirilli Brothers, while John Gregory carved bas-reliefs for the exterior of the C Street entrance. Samuel Yellin, a noted wrought-iron craftsman from Philadelphia, designed and executed numerous railings, gates, and fixtures throughout the building. Milford pink granite was used as a building material. Mural artist Ezra Winter painted a large map of the United States for the Board Room, and sculptor Herbert Adams created memorials to President Woodrow Wilson and Senator Carter Glass to occupy niches in the main lobby. The furniture was produced by W. & J. Sloane, New
