1835, "system for conveying words over distance by musical notes" (devised in 1828 by French composer Jean-François Sudré (1787-1862); each tone played over several octaves represented a letter of the alphabet), from French téléphone (c. 1830), from télé- "far" (see tele-) + phone "sound, voice," from PIE root *bha- (2) "to speak, tell, say" (see fame (n.)). Sudré's system never proved practical. Also used of other apparatus early 19c., including "instrument similar to a foghorn for signaling from ship to ship" (1844). The electrical communication tool was first described in modern form by Philip Reis (1861); developed by Scottish-born inventor Alexander Graham Bell (1847-1922), and so called by him from 1876.[telephone etymology, telephone origin, 英语词源]
