Herbert George "H.G." Wells was a prolific English writer in many genres, including the novel, history, politics, and social commentary, and textbooks and rules for war games. He is now best remembered for his science fiction novels, and Wells is sometimes called the father of science fiction, as are Jules Verne and Hugo Gernsback. His most notable science fiction works include The War of the Worlds, The Time Machine, The Invisible Man, and The Island of Doctor Moreau.

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 from an early date an outspoken socialist, often (but not always, as at the beginning of the First World War) sympathising 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 journalist. Novels like Kipps and The History of Mr Polly, which describe lower-middle class life, led to the suggestion, when they were published, that he was a worthy successor to Charles Dickens, but Wells described a range of social strata and even attempted, in Tono-Bungay (1909), a diagnosis of English society as a whole.
