He was an outspoken socialist and a pacifist, his later works becoming increasingly political and didactic. His later novels were more realistic; they covered lower middle class life (The History of Mr Polly) and the 'New Woman' and the Suffragettes (Ann Veronica). He was a prolific writer of both fiction and non-fiction, and produced works in many genres, including contemporary novels, history, and social commentary.
A defining incident of young Wells's life was an accident he had in 1874, which left him bedridden with a broken leg. To pass the time he started reading books from the local library, brought to him by his father. He soon became devoted to the other worlds and lives to which books gave him access; they also stimulated his desire to write. Later that year he entered Thomas Morley's Commercial Academy, a private school founded in 1849 following the bankruptcy of Morley's earlier school. The teaching was erratic, the curriculum mostly focused, Wells later said, on producing copperplate handwriting and doing the sort of sums useful to tradesmen. Wells continued at Morley's Academy until 1880. In 1877, his father, Joseph Wells, fractured his thigh. The accident effectively put an end to Joseph's career as a cricketer, and his earnings as a shopkeeper were not enough to compensate for the loss.
No longer able to support themselves financially, the family instead sought to place their boys as apprentices to various occupations. From 1881 to 1883 Wells had an unhappy apprenticeship as a draper at the Southsea Drapery Emporium. His experiences were later used as inspiration for his novels The Wheels of Chance and Kipps, which describe the life of a draper's apprentice as well as being critiques of the world's distribution of wealth.
Wells's mother and father had never got along with one another particularly well (she was a Protestant, he a freethinker), and when she went back to work as a lady's maid (at Uppark, a country house in Sussex) one of the conditions of work was that she would not have space for husband or children. Thereafter, she and Joseph lived separate lives, though they never divorced and neither ever developed any other liaison. As for Wells, he not only failed at being a draper, he also failed as a chemist's assistant, and after each failure, he would arrive at Uppark -- "the bad shilling back again!" as he said -- and stay there until a fresh start could be arranged for him. Fortunately for Wells, Uppark had a magnificent library in which he immersed himself, reading many classic works, including Plato's Republic, and More's Utopia.
In 1883, Wells's employer dismissed him, claiming to be dissatisfied with his work (a verdict with which Wells later came to agree) and the young man was far from displeased with this ending to his apprenticeship. Later that year, he became an assistant teacher at Midhurst Grammar School, in West Sussex, until he won a scholarship to the Normal School of Science (later the Royal College of Science, now part of Imperial College London) in London, studying biology under T. H. Huxley. As an alumnus, he later helped to set up the Royal College of Science Association, of which he became the first president in 1909. Wells studied in his new school until 1887 with a weekly allowance of twenty-one shillings (a guinea) thanks to his scholarship. This ought to have been a comfortable sum of money (at the time many working class families had "round about a pound a week" as their entire household income)yet in his Experiment in Autobiography, Wells speaks of constantly being hungry, and indeed, photographs of him at the time show a youth so thin as to be virtually starving.
He soon entered the Debating Society of the school. These years mark the beginning of his interest in a possible reformation of society. At first approaching the subject through The Republic by Plato, he soon turned to contemporary ideas of socialism as expressed by the recently formed Fabian Society and free lectures delivered at Kelmscott House, the home of William Morris. He was also among the founders of The Science School Journal, a school magazine which allowed him to express his views on literature and society, as well as trying his hand at fiction: the first version of his novel The Time Machine was published in the journal under the title, The Chronic Argonauts. The school year 1886-1887 was the last year of his studies. In spite of having previously successfully passed his exams in both biology and physics, his lack of interest in geology resulted in his failure to pass and the loss of his scholarship. It was not until 1890 that Wells earned a Bachelor of Science degree in Zoology from the University of London External Programme.
Upon leaving the Normal School of Science, Wells was left without a source of income. His aunt Mary, a cousin of his father, invited him to stay with her for a while, so at least he did not face the problem of housing. During his stay with his aunt, he grew interested in her daughter, Isabel. In 1889-90 he was a teacher at Henley House School where he taught and admired A.A. Milne
During his marriage to Amy, Wells had liaisons with a number of women, including the American birth-control activist and eugenicist Margaret Sanger and novelist Elizabeth von Arnim. In 1909 he had a daughter, Anna-Jane, with the writer Amber Reeves, whose parents, William and Maud Pember Reeves, he had met through the Fabian Society; and in 1914, a son, Anthony West, by the novelist and feminist Rebecca West, twenty-six years his junior. In spite of Amy Catherine's knowledge of some of these affairs, she remained married to Wells until her death in 1927. Wells also had liaisons with Odette Keun and Moura Budberg.
"I was never a great amorist," Wells wrote in Experiment in Autobiography (1934), "though I have loved several people very deeply."
His early novels, called "scientific romances", invented a number of themes now classic in science fiction in such works as The Time Machine, The Island of Doctor Moreau, The Invisible Man, The War of the Worlds, When the Sleeper Wakes, and The First Men in the Moon (all except When the Sleeper Wakes have been made into films). He also wrote other, non-fantastic novels which have received critical acclaim, including Kipps and the satire on Edwardian advertising, Tono-Bungay.
Wells wrote several dozen short stories and novellas, the best known of which is "The Country of the Blind" (1904).
His short story "The New Accelerator" was the inspiration for the Star Trek episode Wink of an Eye.
Though Tono-Bungay was not a science-fiction novel, radioactive decay plays a small but consequential role in it. Radioactive decay plays a much larger role in The World Set Free (1914). This book contains what is surely his biggest prophetic "hit." Scientists of the day were well aware that the natural decay of radium releases energy at a slow rate over thousands of years. The rate of release is too slow to have practical utility, but the total amount released is huge. Wells's novel revolves around an (unspecified) invention that accelerates the process of radioactive decay, producing bombs that explode with no more than the force of ordinary high explosive— but which "continue to explode" for days on end. "Nothing could have been more obvious to the people of the earlier twentieth century," he wrote, "than the rapidity with which war was becoming impossible... [but] they did not see it until the atomic bombs burst in their fumbling hands." Leó Szilárd acknowledged that the book inspired him to theorise the nuclear chain reaction.
Wells also wrote nonfiction. His bestselling two-volume work, The Outline of History (1920), began a new era of popularised world history. It received a mixed critical response from professional historians. Many other authors followed with 'Outlines' of their own in other subjects. Wells reprised his Outline in 1922 with a much shorter popular work, A Short History of the World, and two long efforts, The Science of Life (1930) and The Work, Wealth and Happiness of Mankind (1931). The 'Outlines' became sufficiently common for James Thurber to parody the trend in his humorous essay, "An Outline of Scientists" — indeed, Wells's Outline of History remains in print with a new 2005 edition, while A Short History of the World has been recently reedited (2006).
From quite early in his career, he sought a better way to organise society, and wrote a number of Utopian novels. Usually starting with the world rushing to catastrophe, until people realise a better way of living: whether by mysterious gases from a comet causing people to behave rationally (In the Days of the Comet (1906)), or a world council of scientists taking over, as in The Shape of Things to Come (1933, which he later adapted for the 1936 Alexander Korda film, Things to Come). This depicted, all too accurately, the impending World War, with cities being destroyed by aerial bombs. He also portrayed social reconstruction through the rise of fascist dictators in The Autocracy of Mr Parham (1930) and The Holy Terror (1939).
Wells contemplates the ideas of nature vs. nurture and questions humanity in books such as The Island of Dr. Moreau. Not all his scientific romances ended in a happy Utopia, the future is distopian in When the Sleeper Wakes (1899, rewritten as The Sleeper Awakes, 1910), in part because the white man has made the terrible mistake of arming the Negro. (This instance of open racism may explain why this novel is less popular than his other science fiction.) The Island of Doctor Moreau is even darker. The narrator, having been trapped on an island of animals vivisected (unsuccessfully) into human beings, eventually returns to England; like Gulliver on his return from the Houyhnhnms, he finds himself unable to shake off the perceptions of his fellow humans as barely civilised beasts, slowly reverting back to their animal natures.
Wells also wrote the preface for the first edition of W. N. P. Barbellion's diaries, The Journal of a Disappointed Man, published in 1919. Since "Barbellion" was the real author's pen-name, many reviewers believed Wells to have been the true author of the Journal; Wells always denied this, despite being full of praise for the diaries, but the rumours persisted until Barbellion's death later that year.
In 1927, Florence Deeks sued Wells for plagiarism, claiming that he had stolen much of the content of The Outline of History from a work, The Web, she had submitted to the Canadian Macmillan Company, but who held onto the manuscript for eight months before rejecting it. Despite numerous similarities in phrasing and factual errors, the court found Wells not guilty.
In 1934 Wells predicted that another world war would begin in 1940, a prediction which ultimately came true. 
In 1936, before the Royal Institution of Great Britain, Wells called for the compilation of a constantly growing and changing World Encyclopaedia, to be reviewed by outstanding authorities and made accessible to every human being. In 1938, he published a collection of essays on the future organisation of knowledge and education, World Brain, including the essay, "The Idea of a Permanent World Encyclopaedia."
Near the end of the Second World War, Allied forces discovered that the SS had compiled lists of intellectuals and politicians slated for immediate murder upon the invasion of England in the abandoned Operation Sea Lion. The name "H. G. Wells" appeared high on the list for the "crime" of being a socialist. Wells, as president of the International PEN (Poets, Essayists, Novelists), had already angered the Nazis by overseeing the expulsion of the German PEN club from the international body in 1934 following the German PEN's refusal to admit non-Aryan writers to its membership.
His most consistent political ideal was the World State. He stated in his autobiography that from 1900 onward he considered a world-state inevitable. He envisioned the state to be a planned society that will advance science, end nationalism, and allow people to advance by merit rather than birth. During his work on the League of Nations Charter, he opposed any mention of democracy. He feared the average citizen could never be educated or aware enough to decide major world issues. Therefore he favoured suffrage to be limited to scientists, organisers, engineers, and others of merit, though he believed citizens should have as much freedom as possible without restricting the freedom of others.
His values and political thinking came under increasing criticism from the 1920s and afterwards.
Lenin's attempts at reconstructing the shattered Russian economy, as his account of a visit (Russia in the Shadows; 1920) shows, also related towards that. This is because at first he believed Lenin might lead to the kind of planned world he envisioned. This was in spite of the fact that he was a strongly anti-Marxist socialist who would later state that it would've been better if Karl Marx was never born.
The leadership of Joseph Stalin led to a change in his view of the Soviet Union even though his initial impression of Stalin himself was mixed. He disliked what he saw as a narrow orthodoxy and obdurance to the facts in Stalin. However he did give him some praise saying in an article in the left-leaning New Statesman magazine, "I have never met a man more fair, candid, and honest" and making it clear that he felt the "sinister" image of Stalin was unfair or simply false. Nevertheless he judged Stalin's rule to be far too rigid, restrictive of independent thought, and blinkered to lead toward the Cosmopolis he hoped for.
Wells believed in the theory of eugenics. In 1904 he discussed a survey paper by Francis Galton, co-founder of eugenics, saying "I believe .. It is in the sterilisation of failure, and not in the selection of successes for breeding, that the possibility of an improvement of the human stock lies." Some contemporary supporters even suggested connections between the "degenerate" man-creatures portrayed in The Time Machine and Wells's eugenic beliefs. For example, the economist Irving Fisher said in a 1912 address to the Eugenics Research Association: "The Nordic race will... vanish or lose its dominance if, in fact, the whole human race does not sink so low as to become the prey, as H. G. Wells images, of some less degenerate animal!
In the end his contemporary political impact was limited. His efforts regarding the League of Nations became a disappointment as the organisation turned out to be a weak one unable to prevent World War II. The war itself increased the pessimistic side of his nature. In his last book Mind at the End of its Tether (1945) he considered the idea that humanity being replaced by another species might not be a bad idea. He also came to call the era "The age of frustration."
He spent his final years venting this frustration at various targets which included a neighbour who erected a large sign to a servicemen's club. As he devoted his final decades toward causes which were largely rejected by contemporaries, his literary reputation declined. One critic said, "Mr. Wells is a born storyteller who has sold his birthright for a pot of message.
Wells was a diabetic and a co-founder in 1934 of what is now Diabetes UK, the leading charity for people living with diabetes in the UK.
He died of unspecified causes on 13 August 1946 at his home at 13 Hanover Terrace, Regent's Park, London. Some reports indicate the cause of death was diabetes or liver cancer. In his preface to the 1941 edition of The War in the Air, Wells had stated that his epitaph should be: "I told you so. You damned fools! but his wish was not granted as he was cremated on 16 August 1946 and his ashes later scattered at sea. A commemorative blue plaque in his honour was installed at his home in Regent's Park.
