What appears to be a schematic of the first electric telegraph appears in a letter published on February 1, 1753 in The Scots magazine, signed by a certain CM from Renfrew (a town 10 km west of Glasgow, Scotland) , initials believed to be from Charles Morrison, a surgeon whose idea was to use as many wires as letters of the alphabet (24), producing electrical discharges in the wire associated with the letters of the message. Although he never finished it, it was a good idea.
