Samuel Morse and his partner Alfred Vail tested the first forty-mile telegraph line between Washington and Baltimore on May 24, 1844. In most accounts, a young woman provided the first message they sent: What Hath God Wrought. The long-distance application of the telegraph and Morse code marked the beginning of a new era of communication, where information could travel instantaneously. Telephone, internet, and social networks around the world today began with two points: the Supreme Court Chamber in Washington and the Mount Clair Railway Depot in Baltimore.
