Three Americans, artist Samuel F. B. Morse, physicist Joseph Henry, and machinist and inventor Alfred Vail, developed what in the 1830s?
Morse code and most versatile methods of telecommunication. The most common distress signal is SOS – three dots, three dashes, and three dots – internationally recognized by treaty. Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed an electrical telegraph system. This system sent pulses of electric current along wires which controlled an electromagnet that was located at the receiving end of the telegraph system. A code was needed to transmit natural language using only these pulses, and the silence between them. Around 1837, Morse, therefore, developed an early forerunner to the
Alfred Vail Clerk the residents retained the rights to the original Charter of Shrewsbury Township Est. 1693. This housing development exists to this day under that name. An elementary school near the Speedwell Works, in Morristown, New Jersey, is named "Alfred Vail." Alfred Vail Alfred Lewis Vail (September 25, 1807 – January 18, 1859) was an American machinist and inventor. Along with Samuel Morse, Vail was central in developing and commercializing American telegraphy between 1837 and 1844. Vail and Morse were the first two telegraph operators on Morse's first experimental line between Washington, DC, and Baltimore, and Vail took charge of building
