Stereo Recording

In the age of 5.1 and even 7.1 Surround Sound, the concept of stereo seems almost antiquated. But when Roscoe Bartlett was born, all you had was mono. Mono, that's as in one tract of sound. It was not until the 1930's that Bell Labs began experimenting with the idea of recording sound in stereo. They first recorded the Phiadelphia Orchestra in stereo in 1932. Disney's film Fantasia was the first film recorded in stereo in 1940.
