Per Wikipedia, so take that at face value
"The 13-story, brown brick and terra cotta office building[3] with a ground-floor theater was designed by architect Herbert J. Krapp.[1] It was built by Arthur Hammerstein between 1925 and 1927,[1] and was named Hammerstein's Theater after his father, Oscar Hammerstein I.The original neo-Gothic interior contained pointed-arch stained-glass windows with scenes from the elder Hammerstein's operas; during a 1993 renovation, these windows were removed and stored by CBS in an arrangement with the New York City Landmarks Preservation Commission.[3] Its first production was the three-hour musical Golden Dawn, the second male lead of which was Cary Grant, then still using his birth name, Archie Leach.[3] Arthur Hammerstein went bankrupt in 1931, and lost ownership of the building.[3]
It later went by the name Manhattan Theater, Billy Rose's Music Hall, and the Manhattan once again.[citation needed] In the 1930s, it became a nightclub.[citation needed] After CBS obtained a long-term lease on the property, the radio network began broadcasting from there in 1936, moving in broadcast facilities it had leased at NBC Studios in Radio City.[3] Architect Williams Lescaze renovated the interior, keeping nearly all of the Krapp design but covering many walls with smooth white panels, his work earning praised from the magazine Architectural Forum.[3] The debut broadcast was the Major Bowes Amateur Hour.[3] The theater had various names during the network's tenancy, including Radio Theater #3 and the CBS Radio Playhouse.[citation needed] It was converted for television in 1950, when it became CBS-TV Studio 50.
