H.G. Wells wrote several novels that have a post-apocalyptic theme. "The Time Machine" (1895) has the unnamed protagonist traveling to the year 802,701 A.D. after civilization has collapsed and humanity has split into two distinct species, the elfin Eloi and the brutal Morlocks. Later in the story, the time traveler moves forward to a dying Earth beneath a swollen red sun. "The War of the Worlds" (1898) depicts an invasion of Earth by inhabitants of the planet Mars. The aliens systematically destroy Victorian England with advanced weaponry mounted on nearly indestructible vehicles. Due to the infamous radio adaptation of the novel by Orson Welles on his show, "The Mercury Theatre on the Air", the novel has become one of the best known early apocalyptic works. It has subsequently been reproduced or adapted several times in comic books, film, music, radio programming, television programming, and video games.
