Samuel Morse was an artist that invented the telegraph. He went to England to study painting, but later found an interest in electricity. In 1832, he saw someone using an electromagnetic device. This gave him the idea to use electricity to send messages. Even though he did not know much about electricity, he could use his artist skills to sketch drawings of his proposed machine. Joseph Henry, a physicist, helped Morse figure out how the machine would work. This machine would be called the telegraph. It conveyed electrical messages over a wire between two places. He was issued a patent, and built a 40 mile telegraph line from Baltimore to Washington D.C. The first message using the telegraph was "What hath God wrought." In order to send this message, he had to use a message system called Morse Code. This is made up of dots and dashes that were relayed on the telegraph. The telegraph was the start of the development of modern communication systems. Although the telegraph is no longer used, we now have devices such as telephones, fax machines, and the Internet that complete the same tasks in more improved ways.
