What was the first message ever sent in Morse Code?

“What Hath God Wrought”

Answer: Sent by inventor Samuel F.B. Morse on May 24, 1844, over an experimental line from Washington, D.C., to Baltimore, the first message ever sent in Morse Code said: “What hath God wrought?” Taken from the Bible, Numbers 23:23, and recorded on a paper tape, the phrase had been suggested to Morse by Annie Ellsworth, the young daughter of a friend. Each code character’s corresponding letter was subsequently handwritten underneath by Morse himself. The success of the experiment would change forever the national communication system.
