"Ralph 124C 41+" by Hugo Gernsback is a science fiction novel serialized beginning in 1911 and published in book form in 1925. Set in the year 2660, it follows a brilliant inventor who saves a woman's life using remote energy transmission, then later rescues her from a villain in outer space. Despite being criticized for poor writing, the novel remarkably predicted technologies like television, radar, solar energy, videophones, tape recorders, and space travel decades before their invention.
