Nobody discovered the telegraph, they invented it.
The inventor of the telegraph was Samuel Morse, who first made it in 1837. This device he invented was very small, and was used for communication. With this people were able to spread news faster and hold long distance relationships/communications with someone in a different city. They would transmit the message as a series of dots and dashes called "Morse Code."
For example, the Morse Code for "SOS" would translate as: "Dot, dot, dot, dash dash dash, dot dot dot" (... _ _ _ ...)
A more complex sentence would appear as the following:
It is going to rain tomorrow, shall we cancel the meeting?
.. _ .. ... __. ___ .. _. __. _ _ _ _ ._. ._. .. _. _ _ (continuation for a few lines longer)
If there was a break in the sentence it would look like the following:
How are you? I'm fine. _.. _ _ _./ _ _ _ ._. .._
People were trained to decode these messages quickly in case of urgency.
Telegraphy was discovered First and then Telephony was discovered much later by Alexander Graham Bell.

well the guy that made this thingy wanted to build something so he did and that is why there was an electric telegraph invented.
Steel was "discovered" over 4,000 years ago, so yes.
Samuel F. B. Morse That is where Morse code got it's name.

Yes a telegraph can be wireless. Thomas Edison invented the first wireless telegraph
The Barclay brothers puchased the Telegraph Group , which included the The Daily Telegraph, Sunday Telegraph and The spectator, from Hollinger in 2004.

HOW THEY MADE A MORSE CODE MACHINE Samuel F.B. Morse and Alfred Vail developed an electric telegraph which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire.
A telegraph circuit is an electrical circuit attached to a telegraph. This circuit is incomplete until the telegraph is connected, allowing for the Morse-code messages by tapping the circuit closed.
