Old Wires and New Waves- The History of the Telegraph, Telephone and Wireless By Alvin F. Harlow. Originally published in 1936. FOREWORD: THERE may be those who will think that a disproportionate amount of space is given in this book to the early history of the telegraph, as against the remarkable technical develop ments of the past quarter or half century.
