The term Steampunk was first coined in 1987 by K. W. Jeter, the author of the novel Morlock Night. He used the term to describe a genre of speculative fiction in which steam, not electricity, drove technological advancements. Since then it has been used to describe an artistic and cultural movement. Authors such as Tim Powers, James Blaylock, William Gibson, and Bruce Sterling have have created worlds inspired by the Victorian Era, giving rise to the modern conception of "steampunk". These authors were heavily influenced by nineteenth century writers H. G. Wells and Jules Verne, who are often considered the forefathers of steampunk.
