This ebook traces the history of the telephone from the primitive ‘electric telegraph’, invented by the British scientist Sir Francis Ronalds in 1816, to the development of fibre optic cables in the 21st century.
With over 400 thumbnail images, it gives an overview of progress in telecommunications technologies and the people behind them, including the first telegraph line erected and used in 1829 by Harrison Gray Dyar Sr in the United States of America, Samuel Morse of Morse Code fame, and Alexander Graham Bell, the inventor of the telephone.
