Lee de Forest was a telecommunications inventor, responsible for the Audion vacuum tube. In 1907, his "radiophone" allowed phonograph music and human voice to broadcast wirelessly. The device used a "singing arc" to generate radio carrier signals. The US Navy purchased six radiotelephones for installation on the Great White Fleet. This is one of the earliest radiotelephones made by de Forest.
