"Ralph 124C 41 +, by Hugo Gernsback, is an early science fiction novel, written as a twelve-part serial in Modern Electrics magazine, which Gernsback edited, beginning in April 1911. It was compiled into novel/book form in 1925. While it pioneered many ideas found in later science fiction, it has been critically panned for its "inept writing." The title contains a gramogram, meaning "One to foresee for one another." In the introduction to the first volume of Science-Fiction Plus, dated March 1953, Gernsback called for patent reform to give science fiction authors the right to create patents for ideas without having patent models because many of their ideas predated the technical progress needed to develop specifications for their ideas. The introduction referenced the numerous prescient technologies described throughout Ralph 124C 41+." (from Wikipedia).…

"Gernsback provided a forum for the modern genre of science fiction in 1926 by founding the first magazine dedicated to it, Amazing Stories. The inaugural April issue comprised a one-page editorial and reissues of six stories, three less than ten years old and three by Poe, Verne, and Wells. He said he became interested in the concept after reading a translation of the work of Percival Lowell as a child. His idea of a perfect science fiction story was "75 percent literature interwoven with 25 percent science". As an editor, he valued the goal of scientific accuracy in science fiction stories: "Not only did Gernsback establish a panel of expertsall reputable professionals from universities, museums, and institutesto pass judgment on the accuracy of the science; he also encouraged his writers to elaborate on the scientific details they employed in their stories, comment on the impossibilities in each other's stories, and even offered his readers prize money for identifying scientific errors."
