As you explore the PhonoJack site, don't take it too seriously. Please smile as you read about the men and machines in the early Phonograph industry.  During their venture-stage years, some of the great inventors involved with phonographs including Thomas Edison, Emile Berliner, Charles Sumner Tainter and Alexander Graham Bell all worked in the same "Charles Williams Building". This was birthplace of Bell's telephone and Edison's first patented device, the vote recorder located at 109 Court Street in Boston.  There's a small monument to Alexander Graham Bell nearby. There's no doubt their experience with telegraphs and telephones prompted them to develop phonograph technology. I'm hooked on a variety of people and machines in the antique phonograph hobby.
