Have you ever heard of the telegraphone? I know i haven't! It was invented by Valdemar Poulsen in 1899 although no one heard about it until the late 1950's. It was the first device that could record sound. It could record with either tapes, wire, or disks. Did you know that? It was a very popular with businesses and just regular housing. The Telegraphone was mostly sold as consumer technologies after World War II. But then in 1948, the magnetic tape recorder was invented and put the telegraphone off of the market.

ReplyDeleteI've heard of one, though I've never actually heard one.
ReplyDeleteHmm indeed.
ReplyDeleteI've heard of them, and believe I've seen one in person in a museum. They sound entertaining.
