Electrical Experimenter

"The Electrical Experimenter was an American technical science magazine that was published monthly. It was established in May 1913, as the successor to Modern Electrics, a combination of a magazine and mail-order catalog that had been published by Hugo Gernsback starting in 1908 [sold in 1913]. The Electrical Experimenter continued from May 1913 to July 1920 under that name, focusing on scientific articles about radio, and continued with a broader focus as Science and Invention until August 1931." --Wikipedia
