Historians usually set the birth of electronics at 1904-6, with the invention of vacuum tubes, namely the thermionic diode (valve) by John A. Fleming, the triode (Audion) by Lee De Forest, and the cathode-beam relay by Robert von Lieben. These inventions allowed easy electrical rectification, amplification and switching and paved the way for a number of thermionic devices, upon which almost 40 years of telephone, radio, radar, television and audio technologies were built. Solid-state electronics spread out after World War II, following the invention of the bipolar transistor by Bardeen, Brattain and Shockley in 1947-8, marking the era of semiconductor devices which eventually superseded thermionic tubes. It is little known that the first solid-state devices were made much earlier, even before thermionic tubes were conceived.

Abstract
Historians usually set the birth of electronics at 1904-6, with the invention of vacuum tubes, namely the thermionic diode (valve) by John A. Fleming, the triode (Audion) by Lee De Forest, and the cathode-beam relay by Robert von Lieben. These inventions allowed easy electrical rectification, amplification and switching and paved the way for a number of thermionic devices, upon which almost 40 years of telephone, radio, radar, television and audio technologies were built. Solid-state electronics spread out after World War II, following the invention of the bipolar transistor by Bardeen, Brattain and Shockley in 1947-8, marking the era of semiconductor devices which eventually superseded thermionic tubes. It is little known that the first solid-state devices were made much earlier, even before thermionic tubes were conceived.
