U.S. Capitol - site of the first long-distance telegraph transmission

On May 24, 1844, Samuel F. B. Morse sent the message 'What hath God wrought' from the telegraph instrument installed in the U.S. Capitol to Baltimore, demonstrating early long-distance electric telegraphy in the nation's capital. The event is documented as a pivotal public demonstration of telegraph technology in the United States. The Capitol location has since been cited in histories of early telecommunications as the origin point for that demonstration.
