replicate the original conditions of the auditorium's features. These renovations were undertaken with donations from the Charity Randall Foundation which was established in 1977 to remember the sister of Pitt graduate and businessman Robert Randall and to support her interest in the arts after her death in a car accident. The plush, deep red seats, identical to those first installed New York's Radio City Music Hall, were reupholstered and their wrought iron frames and oak arms refinished to their original 1930s condition. The number of seats were reduced from 572 to 478, including the addition of 24 new freestanding balcony seats. Other auditorium improvements include new carpeting and new lighting that highlights the vaulted stone ceiling, as well as a restoration of the original Samuel Yellin designed chandelier. In addition, state-of-the-art sound, lighting, and production equipment was added, as well as a new rigging system, actors' restroom, and various stage improvements. Pittsburgh Irish and Classical Theatre has staged many productions in this space. Henry Heymann Theatre The downstairs of the Stephen Foster Memorial houses the 153-seat Henry Heymann Theatre, featuring a thrust stage with seating on three sides. The theater honors the university's longtime scenic designer, and theater donor, Henry Heymann, who taught scenic design from 1968 until he retired in 1993. The Heymann Theatre was created in 2000 in a space that formerly served as the memorial's social room, which hosted USO dances during World War II. A little-known tunnel also extends from the Heymann Theatre to under the loading dock level of the Cathedral of Learning, connecting the two buildings. During the 2003 renovations to the memorial, the downstairs dressing room area was reconfigured to accommodate three "star" dressing rooms and men's and women's showers. Pittsburgh Irish and Classical Theatre has also staged many productions in this space. Richard E. Rauh Studio Theater The Richard E. Rauh Studio Theatre, located in the lower level of the Cathedral of Learning in Room 72, is a typical black box theater in that it is a square, unadorned room with black walls, a flat floor, and chairs that can be moved or removed to accommodate a particular production. It was originally designed in the early 1960s by Ned Bowman, associate professor of Speech and Theatre Arts. It is home to student-directed laboratory productions, play readings, Dark Night Cabaret, and plays host to Pittsburgh's longest-running theater show, Friday Nite Improvs, started in
