Wikipedia states that:
Steampunk is a sub-genre of science fiction, fantasy, alternate history, and speculative fiction that came into prominence during the 1980s and early 1990s. Steampunk involves a setting where steam power is still widely used—usually Victorian era Britain or "Wild West"-era United States—that incorporates elements of either science fiction or fantasy.

G. Wells and Jules Verne, or the contemporary authors Philip Pullman, Scott Westerfeld and China Mieville.
