1637
Samuel Morse was involved in the invention of the single wire telegraph system. This system was based on the European telegraph.
The electrical telegraph system was not created until the 1800s. The closest thing to the telegraph in the 1700s was a visual semaphore system. The Morse system, using a telegraph key to send a system of dots and dashes (Morse Code) was patented in 1837.
