Who invented the history of telegraph?

Telegraph, its inventor is American Morse. He successfully developed the telegraph in 1837, and later, after years of efforts, he developed a point, line and plane system, which opened a new era of electronic communication. There is another saying: when it comes to telegrams, people will immediately think that it was invented by the famous American painter Morse. In fact, although the patent for this invention was first obtained by Morse, Weber and his mentor and collaborator Gauss were the real inventors. 1920 oster discovered the magnetic effect of current. This effect can be used to transmit signals. Many people have done a lot of research and exploration on it in the future. 1833, Weber and Gauss set up a wire between the Observatory and the Physics Museum of the University of G? ttingen, 9000 feet away. The battery is used as the power supply, and the signal is transmitted by ringing the bell by electromagnetic force. This is the earliest cable telegraph equipment, which is even better than the cable telegraph invented by Morse (1937) and has been patented.
