Dots, Dashes and a Wire

Samuel Morse began as a portrait painter. When his wife died in 1825, news reached him too late, and he arrived home after the funeral, a loss that inspired his interest in faster messages.

With partner Alfred Vail, Morse developed the telegraph and a code of dots and dashes, short and long signals. The US Congress funded a line between Washington and Baltimore, and in 1844 the first official message, What hath God wrought, a phrase from the Bible, was sent.

The telegraph spread quickly, letting messages cross distances almost instantly. Morse code later carried the famous distress signal SOS, three dots, three dashes and three dots, and is still used by some radio operators today.
