mr. caruso's voice. robably obviously the most famous tenor of all time, even modern day tenors still use henrique caruso as a guide for a beautiful voice. eldridge johnson was really concerned with fidelity, and he would over and over made improvements to the way that the sound was transmitted through the horn. and eventually, in 1906, he was able to patent the inside horn machine, and he called it a victrola which is kind of a generic term today. we get a lot of questions from people, and they say oh, they got a victrola when in reality it could be another machine made by a company not made by victor. but that was a real success to put the horn, which kind of had become an accessory that a lot of people got tired of maneuvering around, because it was delicate, and then it's kind of like a magic thing that happened. the horn was folded upon itself and kind of sandwiched or stuffed into that little box, and that was his major invention. i would say, in making this little tiny machine play so well. >> mr.
