for new architectural identities in the wake of the Great Depression and the Second World War. Formally, the building's massing and articulation responded to an established government style, the stripped classical. This style was promoted chiefly through the work of Paul Philippe Cret, who sat on numerous local, national, and international architectural juries, held a 34-year tenure at the University of Pennsylvania and served as a member of the tenets of European modernism, but married them with a traditional and classical design vocabulary. Through its symmetrical mass, attenuated verticals and vaguely cubist sculptural element, the E. Barrett Prettyman Federal Courthouse recalls the work of Cret, Wyeth, and U.S. Supervising Architect of the Treasury, Louis A. Simon. Justement arranged the building's interior spaces in such a way that the building would "not only provide adequate quarters for the efficient operation of the Circuit and District Courts and their allied activities for a number of years to come, but would also provide for the convenience and comfort of the judges, attorneys, jurors, witnesses and others who will be required to use the building." These diverse functions mandated innovative programmatic solutions. To give adequate security and segregate public from private spaces, Justement adopted a unique network of primary and secondary circulation, with five distinct transportation cores and a series of main hallways flanked by ancillary circulation spaces. Justement placed the two courts on separate floors to isolate and separate their functions from one another. The District Court occupied most of the floors: two, four and six. The Court of Appeals, which did not require jury deliberation space to as many courtrooms, occupied floors three and five. The first six floors of the E. Barrett Prettyman Federal Courthouse were similar in plan. Four elevators opened into a small lobby that accessed the main, double-loaded east-west corridor. The main hallway traveled nearly the entire width of the building and intersected secondary corridors at each end. The secondary corridors, which traveled north-south, provided access to the office spaces. On floors two, four, five, and six, the secondary corridors also connected to guarded entrances, which controlled access to private judges' corridors. The length of the secondary corridors varied by floor. Courtrooms, however, appeared in set locations. Floors two and four each held seven courtrooms. The courtrooms on the second floor feature recycled mahogany wood, including pieces from the last Supreme Court renovation that began in 2003. The
