Legacy

The science fiction historian John Clute describes Wells as "the most important writer the genre has yet seen", and notes his work has been central to both British and American science fiction. Science fiction author and critic Algis Budrys said Wells "remains the outstanding expositor of both the hope, and the despair, which are embodied in the technology and which are the major facts of life in our world". He was nominated for the Nobel Prize in Literature in 1921, 1932, 1935, and 1946. Wells so influenced real exploration of Mars that an impact crater on the planet was named after him.

             Wells's genius was his ability to create a stream of brand new, wholly original stories out of thin air. Originality was Wells's calling card. In a six-year stretch from 1895 to 1901, he produced a stream of what he called “scientific romance” novels, which included The Time Machine, The Island of Doctor Moreau, The Invisible Man, The War of the Worlds and The First Men in the Moon. This was a dazzling display of new thought, endlessly copied since. A book like The War of the Worlds inspired every one of the thousands of alien invasion stories that followed. It burned its way into the psyche of mankind and changed us all forever.

In the United Kingdom, Wells's work was a key model for the British “scientific romance”, and other writers in that mode, such as Olaf Stapledon, J. D. Beresford, S. Fowler Wright, and Naomi Mitchison, all drew on Wells's example. Wells was also an important influence on British science fiction of the period after the Second World War, with Arthur C. Clarke and Brian Aldiss expressing strong admiration for Wells's work. Among contemporary British science fiction writers, Stephen Baxter, Christopher Priest and Adam Roberts have all acknowledged Wells's influence on their writing; all three are Vice-Presidents of the H. G. Wells Society. He also had a strong influence on British scientist J. B. S. Haldane, who wrote Daedalus; or, Science and the Future (1924), "The Last Judgement" and "On Being the Right Size" from the essay collection Possible Worlds (1927), and Biological Possibilities for the Human Species in the Next Ten Thousand Years (1963), which are speculations about the future of human evolution and life on other planets. Haldane gave several lectures about these topics which in turn influenced other science fiction writers.

In the United States, Hugo Gernsback reprinted most of Wells's work in the pulp magazine Amazing Stories, regarding Wells's work as "texts of central importance to the self-conscious new genre". Later American writers such as Ray Bradbury, Isaac Asimov, Frank Herbert and Ursula K. Le Guin all recalled being influenced by Wells's work.

Sinclair Lewis's early novels were strongly influenced by Wells's realistic social novels, such as The History of Mr Polly; Lewis also named his first son Wells after the author.

In an interview with The Paris Review, Vladimir Nabokov described Wells as his favourite writer when he was a boy and "a great artist". He went on to cite The Passionate Friends, Ann Veronica, The Time Machine, and The Country of the Blind as superior to anything else written by Wells's British contemporaries. In an apparent allusion to Wells's socialism and political themes, Nabokov said: "His sociological cogitations can be safely ignored, of course, but his romances and fantasies are superb".

Jorge Luis Borges wrote many short pieces on Wells in which he demonstrates a deep familiarity with much of Wells's work. While Borges wrote several critical reviews, including a mostly negative review of Wells's film Things to Come, he regularly treated Wells as a canonical figure of fantastic literature. Late in his life, Borges included The Invisible Man and The Time Machine in his Prologue to a Personal Library, a curated list of 100 great works of literature that he undertook at the behest of the Argentine publishing house Emecé. Canadian author Margaret Atwood read Wells' books and he also inspired writers of European speculative fiction such as Karel Čapek and Yevgeny Zamyatin.
