Who invented the telegraph?

The telegraph, a revolutionary method of long-distance communication, was primarily invented by Samuel Morse. Morse's work in the 1830s and 1840s led to the development of an electrical signaling system that utilized coded messages, famously known as Morse code. His first successful demonstration of the telegraph took place in 1844 when he transmitted the message "What hath God wrought" from Washington, D.C., to Baltimore, Maryland. This invention had a profound impact on communication, facilitating the rapid exchange of information over great distances and transforming industries such as journalism, business, and transportation. Morse's contributions to the technology and its practical application firmly establish him as the key figure behind the telegraph's invention.
