The complete development of Early Experimental Ideas, Invention & Design from 1830-1930, starting with the old Military and Naval Signal Flags still in use today, each flag spells an alphabetic message, letter by letter.
The next stage was the electric telegraph, the switching of electric current and needles, spelling out a letter-coded message.
Finally, the speaking telephone, now the mini-computer: camera /smartphone we know today, with easy downloads.
1.21 Early Experimental Ideas, Invention & Design: 1830-1930 Harrison Gray Dyar, William Fothergill Cooke, Charles
Wheatstone and Samuel Morse, using diffent methods of experimental and practical switching, to recording sound 1860 and

7.28 Telephone History Visual Index with 114 engravings, all originals, Catalogue Images for research.
The full illustrated story takes you from the original Telegraph visual signals to electrical pulses. To Morse-Code, and world wide cables connecting major cities, over-land Telephones, making the World-Wide-Web possible, today.
