Scientific Intelligence: Morse's Electro-Magnetic Telegraph in The American Journal of Science and Arts 32 No. 1 pp. 185-187, October 1837 [FIRST ANNOUNCEMENT OF MORSE'S SINGLE-WIRE TELEGRAPH]

1837. 1st Edition. FIRST EDITION IN ORIGINAL WRAPPERS of the first announcement of Samuel Morse's single-wire telegraph system and description of an early form of Morse code to be used to communicate on the system. The report is technically detailed and illustrated. Morse’s telegraph includes “a Register which permanently records in characters easily legible the fullest communication, and the use of but one wire as a conductor; although for greater convenience of communicating at all times, and of having a whole circuit at command from each extremity of the line he will use four wires” (AJSA, p. 186).



By December 1837, Morse had enough confidence in his new system to apply for the federal government's appropriation, and during the next year he conducted demonstrations of his telegraph both in New York and Washington. Most systems required multiple wires, “but the system developed in the United States by Morse and Vail was a single-wire system. This was the system that first used the soon-to-become-ubiquitous Morse code. By 1844, the Morse system connected Baltimore to Washington, and by 1861 the west coast of the continent was connected to the east coast” (Wikipedia). Item #1514
