Practical applications started with the invention of the diode by Ambrose Fleming and the triode by Lee De Forest in the early 1900s, which made the detection of small electrical voltages such as radio signals from a radio antenna possible with a non-mechanical device. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age. ![]() ![]() ![]() One of the earliest Audion radio receivers, constructed by De Forest in 1914.Įlectronics has hugely influenced the development of modern society.
