Lee de Forest
A double-bill performance of "Cavalleria" and "Pagliacci" was transmitted as the first broadcast by New York City's Metropolitan Opera on 11 December 1910. Radio pioneer Lee de Forest talked Giulio Gatti-Casazza, the Met manager, into sending the program over the airwaves by using a backstage radio transmitter and a rooftop antenna, "using a long fishing pole for his mast." Enrico Caruso and Emmy Destinn were in the leading roles.
