Maxine Elliott's Theatre was originally a Broadway theatre at 109 West 39th Street in the Midtown Manhattan neighborhood of New York City. Built in 1908, it was designed by architect Benjamin Marshall of the Chicago-based firm Marshall and Fox, who modeled the façade after the neoclassical Petit Trianon in Versailles. In later years, it was known as WOR Mutual Radio Theatre (1941–1944), CBS Radio Playhouse No. 5 (1944–1948), and CBS Television Studio No. 44 or CBS Television Studio Studio 51 (1948–1956). The theater was demolished in 1960 to make way for the Springs Mills Building.
