George Merrick and John Bowman opened the Biltmore in 1926 with a 315-foot tower copied from the Giralda in Seville and the largest hotel pool in the world, where Johnny Weissmuller taught swimming before he played Tarzan. Thomas "Fatty" Walsh was shot dead on the thirteenth floor in 1929. The Army took the hotel in 1942 and turned it into a military hospital; it stayed a veterans' hospital until 1968, then sat empty for fifteen years. Coral Gables got it back under the Legacy of Parks program and reopened it in 1987.
