Herbert George Wells was an English writer. Prolific in many genres, he wrote dozens of novels, short stories, and works of social commentary, history, satire, biography, and autobiography. His work also included two books on recreational war games. Wells is now best remembered for his science fiction novels and is often called the "father of science fiction", along with Jules Verne.

During his own lifetime, however, he was most prominent as a forward-looking, even prophetic social critic who devoted his literary talents to the development of a progressive vision on a global scale. A futurist, he wrote a number of utopian works and foresaw the advent of aircraft, tanks, space travel, nuclear weapons, satellite television, and something resembling the World Wide Web. His science fiction imagined time travel, alien invasion, invisibility, and biological engineering.

Wells's earliest specialized training was in biology, and his thinking on ethical matters took place in a specifically and fundamentally Darwinian context. He was also an outspoken Socialist from a young age, often (but not always, as at the beginning of the First World War) sympathizing with pacifist views. His later works became increasingly political and didactic, and he wrote little science fiction, while he sometimes indicated on official documents that his profession was that of a journalist. Novels such as Kipps and The History of Mr. Polly, which describe lower-middle-class life, led to the suggestion that he was a worthy successor to Charles Dickens, but Wells described a range of social strata and even attempted a diagnosis of English society as a whole.
