Eventually communication reached an electronic state, and the telegraph was invented. Harrison Dyar, who sent electrical sparks through chemically treated paper tape to burn dots and dashes, invented the first telegraph in the USA. The telegraph was the first piece of equipment that allowed users to send electronic messages. A more developed version came from Samuel Morse, whose telegraph printed code on tape and was operated using a keypad and an earpiece. The pattern of communication soon became known as Morse code.
Telectroscope
In reality, the imagined "telectroscopes" described in the articles had nothing to do with the device being developed by Dr. Bell and his assistant Charles Sumner Tainter which was christened with the ambiguous name "photophone". The photophone was actually a wireless optical telephone that conveyed audio conversations on modulated lightbeams, the precursor for today's fiber-optic communications. Bell and Tainter would receive several patents in 1880/1881 for their then cutting-edge invention (master ), which ironically used the same selenium materials in its receivers that created the initial excitement surrounding the telectroscope's proposals.
