Samuel F. B. Morse.
In 1838 Samuel Morse perfected Joseph Henry's invention of the electromagnet. It was not until 1843 that the government funded a telegraph graph line from Washington to Baltimore.
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.

The difference is the telegraph required wires; the radio did not. But other then that, they were mostly the same.
Beginning in the 1850s, Western Union was making use of telegraphy, sending Morse code messages over long distances, by means of telegraph wires. The Bell system was not in existence as a long-distance communication system yet, so Western Union had the clear advantage. When Bell perfected telephonic communication, a person no longer needed to know Morse code in order to send a message. However, in 1877, the telephone was still in the experimental stage, whereas the telegraph was well-known and widely used.
