WASHINGTON DC 1906, American Telegraphone Company Stock Certificate

Description

The certificate was issued on September 19, 1906. The company was incorporated in Washington DC in 1903.
Danish inventor  Valdemar Poulsen developed and patented the audio wire recorder, which he called the “telegraphone” in 1899 and tried to sell the rights in various countries to manufacture it. In the United States, the rights were purchased in 1903 by a group of investors. They established the American Telegraphone Company of Washington, D.C. A factory was set up in Wheeling, West Virginia, but it was later moved to Springfield, Connecticut.
American Telegraphone sold telegraphones for use as scientific instruments, telephone answering machines, and office dictating systems. While several hundred were sold to curious scientists, only one or two were actually used for telephone or dictation recordings. After a few years, American Telegraphone closed its doors, and the magnetic recorder was not heard from in the United States for many years.
