American Inventor, Popularizer of the Telegraph System and Morse Code
Samuel Morse (1791–1872) was originally a portrait painter of some fame, who in 1832, during a transatlantic voyage, was deeply inspired after hearing fellow passengers discuss the principles of electromagnetism, and thereafter turned to the development of telegraph technology, perfecting with his collaborator Alfred Vail a practical single-wire telegraph system and designing "Morse code," a scheme representing letters and numbers by combinations of dots and dashes. In 1844, with Congressional funding, he built an experimental telegraph line from Washington to Baltimore and sent the famous message "What hath God wrought," marking the telegraph’s formal entry into practical use. The spread of the telegraph system let long-distance information transmission for the first time break free of the physical limit of relying on physical carriers such as horses and ships, achieving near-real-time transmission, and profoundly changed the workings of journalism, financial trading, military command, railway dispatch, and many other fields; Morse code later gave rise to the internationally common distress signal "SOS," still used today in some emergency communication and amateur radio.
Morse was in his early years a portrait painter of some reputation, and on the 1832 voyage returning from Europe to America was deeply moved by chancing to hear fellow passengers discuss the latest research in electromagnetism, thereafter resolutely changing course to throw himself into telegraph development — this "mid-career switch" is a typical case in the history of technology of cross-field inspiration triggering a major technical breakthrough.
On 24 May 1844 Morse sent the first formal telegram from the US Capitol to Baltimore, its message quoting the Book of Numbers, "What hath God wrought"; the successful transmission of this telegram marked the telegraph’s formal move from the laboratory to practical use, and telegraph lines thereafter spread swiftly across the United States and Europe, wholly changing the speed and manner of long-distance information transmission.
