Autograph was a small label, owned by Marsh Laboratories Incorporated of Chicago, Illinois.
Marsh Laboratories in turn was owned by electrical engineer Orlando R. Marsh.
Marsh made recordings by his own experimental methods, and therefore Autograph was the first US record label to release recordings made electrically with microphones, as opposed to the acoustical or mechanical method then still universally used.
According to Rust, Marsh's first electrical records were made in 1924, but it actually could have been earlier.
