The telegraphone was the first practical apparatus for magnetic sound recording and reproduction. It was an ingenious apparatus for recording telephone conversations. It recorded, on a wire, the varying magnetic fields produced by a sound. The magnetized wire could then be used to play back the sound. That was the first automatic answering machine

This answering machine was a three-foot-tall machine popular with Orthodox Jews who were forbidden to answer the phone on the Sabbath. The Ansafone, created by inventor Dr. Kazuo Hashimoto for Phonetel, was the first answering machine sold in the USA, beginning in 1960.
