In the 1890s He was a New York socialite, living in the swanky central park south neighborhood, what is now in the center of Midtown on the edge of the Theater district. It was there that he operated his New York phonograph laboratory. He made of extrordinary recordings of the Pope, mark Twan and President Benjamin Harrison. Bettini cylinders are among the rarest in existence. His catalog of opera recordings was 12 pages long, and the cylingers cost $6 when Edison cylinders cost under a dollar. He was selling to a specific clientele.
Before WWI he brought many of his rare recordings to Europe. During the war most of them were destroyed leading to their obscurity. He died in 1938 in San Remo, Italy.
