John Joseph Fahie (1846–1934) was an engineer for the Electric and International Telegraph Company before being posted overseas in the Indo-European Government Telegraph Department. He was also a respected historian whose History of Wireless Telegraphy (1899) sold out two impressions in little over a year. In this second edition (1901), he traces the development of wireless communication during the nineteenth century, drawing extensively from the correspondence and technical illustrations of inventors themselves. This edition was fully updated to take account of the latest advances in radio technology, including Marconi's latest public demonstrations. As a practising telegraph engineer, Fahie was in the perfect position not only to understand the significance of these developments, but to explain them to a non-specialist audience. Contemporary reviews indicate he did this with great success. His book gives an eyewitness account of the rise of radio technology that still fascinates scholars and enthusiasts today.
