Those inventors were Alexander Graham Bell and Elisha Gray. Both devices were registered at the patent office within hours of each other. There followed a bitter legal battle over the invention of the telephone, which Bell subsequently won. http://www.nationalitpa.com/history-of-the-telephone.html -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ Message-ID: <20161225171553.GA3983@telecom.csail.mit.edu> Date: Sun, 25 Dec 2016 12:15:53 -0500 From: Bill Horne <bill@horneQRM.net> Subject: Telex and TWX History Donald E. Kimberlin Telex certainly should be called the original form of E-Mail. Far from "dead" on a global basis, UN reports published in the "Brittanica Book of the Year" indicate there are about three million Telex lines around the globe. Contrary to the impression international telephone people like to create, direct, immediate access via Telex still exists to more of the world's political entities than does telephone. This has been the case for many years. (Totalitarian governments must like Telex; they have been known to shut down telephone service, but not Telex. The suspected reason: It can be monitored with hard copy easily, and often [has] been, too. Of course, they themselves use it for military messages.) http://www.baudot.net/docs/kimberlin--telex-twx-history.pdf -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ Message-ID: <20161225170208.GA3921@telecom.csail.mit.edu> Date: Sun, 25 Dec 2016 12:02:08 -0500 From: Bill Horne <bill@horneQRM.net> Subject: History of the telephone History of the telephone >From Wikipedia, the free encyclopedia This history of the telephone chronicles the development of the electrical telephone, and includes a brief review of its predecessors. https://en.wikipedia.org/wiki/History_of_the_telephone -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ ********************************************* End of telecom Digest Mon, 26 Dec 2016
