Who is the inventor?
Samuel B. Morse was the first one to create a practical telegraph in 1837 and pattoned it in 1840. Morse worked with a chemistry professor named Leonard Gale who helped improve the battery and the electromagnet in the telegraph so that electric current could travel further distances.
How does the telegraph work?
Morse built a larger model than his first, in 1835, that used an electromagnet to deflect a pencil suspended from a small picture frame that made short marks (dots), or longer marks (dashes), on a paper tape. The length of the marks was determined by the amount of electric current sent over the wire being used.
When did the inventention occur?
After many years of sturrgling to make the 'perfect' telegraph, May 24, 1844, Morse sent the first official telegraph message saying, “What hath God wrought!”
WOW IT WORKED!
The picture above this text, is the Morse alphabet, which was the first way that allowed people to communte using the telegraph.
Why is this invention important to history?
It was the beginning of technological communication. It sparked peoples intrests and gave them a new foundation to build upon that they could easily improve on.
Why was there a need for this invention?
Back then, there wasn't really a way to communicate quickly. If someone was further away, you'd need to send it to them through the mail, which was a very difficult and took along time, so they were in need of a quicker way to communicate.
