Decent Essays

In 1836 Samuel F. B. Morse, Joseph Henry and Alfred Vail created a electrical telegraph. Which is a device that sends electrical currents over long distances through wires, when received on the other end it could either be shown by a light flashing or heard by a clicking sound. One year after Samuel released the telegraph Charles Wheatstone and William Cooke released an improved version of the electrical telegraph. They invented this so that people were able to send information over long distances in a shorter amount of time. In 1844 Samuel sent out his first message to Baltimore, Maryland from Washington D.C. When Morse code was first invented Samuel only made the code for numbers but later added letters to make it quicker to understand.
