The Outline of History, subtitled either "The Whole Story of Man" or "Being a Plain History of Life and Mankind," is a work by H. G. Wells that first appeared in an illustrated version of 24 fortnightly installments beginning on 22 November 1919 and was published as a single volume in 1920. It sold more than two million copies, was translated into many languages, and had a considerable impact on the teaching of history in institutions of higher education. Wells modelled the Outline on the Encyclopedie of Denis Diderot. Many revised versions were produced during Wells's lifetime, and the author kept notes on factual corrections he received from around the world. The last revision in his lifetime was published in 1937. Herbert George Wells (21 September 1866 - 13 August 1946)-known as H. G. Wells was a prolific English writer in many genres, including the novel, history, politics, social commentary, and textbooks and rules for war games. Wells is now best remembered for his science fiction novels and is called a "father of science fiction," along with Jules Verne and Hugo Gernsback. His most notable science fiction works include The Time Machine (1895), The Island of Doctor Moreau (1896), The Invisible Man (1897), and The War of the Worlds (1898). He was nominated for the Nobel Prize in Literature four times. Wells's earliest specialised 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. A diabetic, in 1934 Wells co-founded the charity The Diabetic Association (known today as Diabetes UK).
