Rider (1900–1985) was an American radio engineer best known as publisher and author of over 125 books for radio and television servicing. He founded John F. Rider Publisher Inc., and was responsible for annual volumes of the ''Perpetual Troubleshooter's Manual'' from 1931 to 1954. == Early Years == Born in 1900, John F. Rider grew up during the invention of the vacuum tube by J Ambrose Fleming and Lee DeForest and the invention of radio by Edwin Armstrong. Before getting involved into publishing he served at the rank of Lt Colonel for the US Signal Corps after military service he became a radio engineer for Alfred H. Grebe a manufacturer of radios. According to Alan Douglas, a noted radio historian, Rider may have been one of the many engineers that worked on Grebe's top of the line Synchrophase 7 Receivers in 1927. He states, ''"John Rider was a good engineer, aside from his publishing career. I believe he designed the audio system of the 1927 Grebe Synchrophase 7, arguably the first hi-fi radio (response to 8kHz, way ahead of broadcast standards of the day). He conceived the idea of a tuned analyzer (Chanalyst) and sold the first VTVM using the balanced-bridge circuit that became universal for decades (Voltohmyst). He got his name on several patents in the test-equipment field, and wrote a large number of books himself".'' Rider probably accumulated a lot of knowledge through his military experience and radio engineering which enabled him to work for Hugo Gernsback as editor for Gernsback's Radio Craft Magazine. During the 1920s with the rise of radio manufacturers came the rise of the radio servicing business. The need for radio servicing literature (schematics, parts list, production changes etc.) rose. Gernsback started to produce compilations of servicing data for radio repair. See reference for example. Rider was also an amateur radio operator and his call letters were W2RID. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John F.
