A History of Electric Telegraphy to the Year 1837Divided into sections covering various types of telegraph and famous for having thrown light upon the pioneering work of Edward Davy, this survey of the earliest telegraph systems covers the developments through the commercial patents granted in England to Cooke and Wheatstone before the internationalization of the Morse system. It is the most exhaustive record available of early telegraph pioneers and their inventions, as well as being the first work of an accomplished electrical communications historian. Arno reprinted the sequel in the 1971 History of Broadcasting series. Extremely thorough, with many documents reprinted or extracted this is an essential reference work. |
