Inauguration of the First Telegraph Line

Fans of The Office will remember that the original instant message was "letters attached to baskets of food." However, at least as far as electronic messages go, the original IM was probably sent via Morse Code. On May 24, 1844, Samuel Morse sent a message to inagurate the first telegraph line using a series of dots and dashes which translated into "What hath God wrought" (a biblical quotation from Numbers 23:23). The message was transmitted from the Old Supreme Court Chamber in Washington DC to his assistant, Alfred Vail, in Baltimore, Maryland.
