Lee de Forest

Lee de Forest was an American inventor with over 180 patents to his credit. He named himself the "Father of Radio," and famously said, "I discovered an Invisible Empire of the Air, intangible, yet solid as granite." In 1906 de Forest invented the Audion, the first triode vacuum tube and the first electrical device which could amplify a weak electrical signal and make it stronger. The Audion, and vacuum tubes developed from it, founded the field of electronics and dominated it for forty years, making radio broadcasting, television, and long-distance telephone service possible, among many other applications. For this reason de Forest has been called one of the fathers of the "electronic age". ...more

Michael Faraday Michael Faraday FRS was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis. Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principle of electromagnetic  ...more Michael Faraday

George Westinghouse

George Westinghouse, Jr. was an American entrepreneur and engineer who invented the railway air brake and was a pioneer of the electrical industry, gaining his first patent at the age of 22. Based in Pittsburgh, Pennsylvania for much of his career, Westinghouse was one of Thomas Edison's main rivals in the early implementation of the American electricity system. Westinghouse's electricity distribution system, based on alternating current, ultimately prevailed over Edison's insistence on direct current. In 1911 Westinghouse received the AIEE's Edison Medal "For meritorious achievement in connection with the development of the alternating current system."more George Westinghouse American
