Unrecorded Stories, Novels, and Plays (Source Text Available)
- A.D. 2000 by Alvarado M. Fuller
- Adventures of Peter Wilkins by Robert PaltockA.D. 2000 (1890; vt Back to Life (A.D. 2000): A Thrilling Novel 1911), wakes its protagonist (see Sleeper Awakes) in the Utopian culture of the year 2000, significantly the same year that the protagonist of Edward Bellamy's already hugely influential Looking Backward (1888) awakens. A single party rules North America, and electrical inventions (after a great disaster with "aluminum bronze", electricity has become the chief source of power) dominate the exiguous storyline, which does come to a climax with the discovery of the North Pole.
- Angel Island by Inez Haynes GillmoreRobert Paltock's Adventures of Peter Wilkins, first published in 1750, is often regarded as proto-science fiction and is a great read! The original full title is a good plot summary:
The Life and Adventures of Peter Wilkins, a Cornish Man: Relating Particularly, His Shipwreck Near the South Pole; His Wonderful Passage Thro' a Subterranean Cavern into a Kind of New World; His There Meeting with a Gawry or Flying Woman, whose life he Preserv'd, and Afterwards Married her; His Extraordinary Conveyance to the Country of Glums and Gawrys, or Men and Women That Fly. Likewise a Description of this Strange Country, with the Laws, Customs, and Manners of its Inhabitants, and the Author's Remarkable Transactions Among Them. Taken from his own Mouth, in his Passage to England, from off Cape Horn in America, in the Ship Hector. With an INTRODUCTION, Giving an Account of the Surprizing Manner of his Coming on Board that Vessel, and his Death on his Landing at Plymouth in the Year 1739. Illustrated with Several CUTS, Clearly and Distinctly Representing the Structure and Mechanism of the Wings of the Glums and Gawrys, and the Manner in Which They Use Them Either to Swim or Fly. By R S, a Passenger in the Hector (London: Jacob Robinson and Robert Dodsley, 1750) .
- At the Queen's Mercy by Mabel Fuller BlodgettUS author born in Brazil but raised from infancy in the US, whose sf novel, Angel Island (1914), conveys an almost surreal Feminist message with considerable competence – she had been an active feminist from before the end of the century. Five beautiful winged women, who have enjoyed total freedom, discover five men who have been shipwrecked on the eponymous Island (in the Robinsonade tradition); they are soon captured by the men, who clip their wings and breed with them; the tale gradually makes explicit an outrage at the caging of women, as well as an acute ambivalence about the seemingly willing submission of at least four of them to bondage.
- Back to Methuselah by George Bernard Shaw [a five part series of plays]At the Queen's Mercy (1897) is a tale set in Africa and visibly reflecting the influence of H Rider Haggard in its depiction of a mysterious walled city – Phoenician in origin – ruled by a white queen named La who reigns over black subjects.
- Beyond the Vanishing Point by Ray CummingsShaw's first genuine sf play, an important example of the Scientific Romance, is Back to Methuselah: A Metabiological Pentateuch (1921; rev 1921 UK; performed 1922: further rev several times; much rev 1945), a five-part depiction of mankind's Evolution – it was his culminating presentation of Creative Evolution – from the time of Genesis (see Adam and Eve) into the Far Future, during the course of which people have become long-lived (see Immortality) and, by the year 31,920 CE, are on the verge of suffering corporeal Transcendence into disembodied thought-entities; incidental sf devices include cellphone equivalents, a kind of Force Field and the revelation that by 3000 CE nothing whatever remains of London.
- The Brick Moon by Edward Everett Hale
- Cæsar's Column: A Story of the Twentieth Century by Ignatius DonnellyA short work of speculative fiction containing the first known depiction of an artificial satellite. - 1869
Summary and historical significance: http://www.sacred-texts.com/utopia/cc/index.htm
- The Centaurians by L.D. BiagiHis most important sf novel was Caesar's Column: A Story of the Twentieth Century (1890; early editions under the pseudonym Edmund Boisgilbert), which countered the Utopian optimism of Edward Bellamy with the argument that the world of 1988 was evolving towards greater inequality and catastrophic War rather than towards peace and plenty, all being dramatized through a proletarian revolt which burns New York to the ground, except for a "Caesar's Column" of corpses in Union Square; the protagonist escapes to Africa in a Balloon.
- Clearing the Seas: Or, The Last of the Warships by Donal Hamilton HainesThe protagonist of her sf novel The Centaurians (1911) travels with his Scientist friend in a torpedo-like ship of the latter's Invention to the North Pole and beyond, arriving in a clement Lost World where they sight what seems to be a Counter-Earth. They are taken by members of a primitive tribe to the City of the dark-complected Centaurians (see Race in SF), who display their much advanced Technology and science, and who inform the visitors that the world in the sky is in fact the tenuous aftermath of a destroyed planet. After failing to win the heart of a Princess, the narrator returns to the normal world.
- The Conquest of the Moon: A Story of the Bayouda (by the British Empire!)His two connected sf novels for Young Adult readers, The Last Invasion (1914) and Clearing the Seas; Or, the Last of the Warships (1915), describe various aspects of a moderately futile Future War in which the United States is invaded by the "Blues" (whom E F Bleiler thinks must be Germans), who are eventually driven off, and war itself discounted for good.
http://catalog.hathitrust.org/Record/008611866) by Paschal Grousset 1889
- The Crack of Doom by Robert CromieFrom Wikipedia: One of Grousset's most interesting science fiction novels was Les Exilés de la Terre — Selene-Company Limited* (1887), probably one of the most fanciful cosmic tales of all times. In it, a consortium which intends to exploit the Moon’s mineral resources decides that, since our satellite is too far to be reached, it must be brought closer to the Earth. A Sudanese mountain composed of pure iron ore becomes the headquarters of the newly established Selene Company. Solar reflectors are used to provide the energy required to convert the mountain into a huge electro-magnet, with miles of cables wrapped around it. A spaceship-cum-observatory is then built on top of the mountain. When the experiment begins, the mountain is ripped away from the Earth and catapulted to the Moon. There, the protagonists have various adventures and eventually return to Earth by re-energizing the mountain.

- Dalleszona and the Seventh Treasure by Allen Kendrick WrightCromie is best known for his third sf novel, The Crack of Doom (1895), which is set in the year 2000; the protagonist runs across a politically radical villain (the secret society he controls is vitiated by Feminism and other unacceptable beliefs) who dominates his attractive sister through Telepathy and has also developed a device to unlock the Nuclear Energy contained in matter. He plans to use his formula to destroy the world through a Manichaean conviction that matter is an occlusive evil whose effect on primal reality is to torture it. There is no doubt of Cromie's intention: as he explains, the first use of atomic energy had, thousands of years earlier, destroyed the fifth planet and created the Asteroids; though hazily described; his use here of a nuclear device to end civilization marks the first occurrence of a theme which would dominate the next century (see End of the World). In a heavily plotted denouement, the protagonist alters the formula, so that only a South Pacific Island is evaporated, and all is saved.
- A Demigod: A Novel by Jackson, Edward Payson, 1840-1905Dalleszona and the Seventh Treasure (1922) is a Lost Race tale, featuring descendants of the Toltec Nation whose example inspires world peace after World War One.
- The Diothas; or, A Far Look Ahead by John MacnieA Demigod: A Novel (1886), published anonymously, in which a Eugenics programme, begun in Greece in the seventeenth century, generates in the late nineteenth century a Superman who boasts extraordinary strength and agility, plus a massive intellect, out of which pours Inventions galore, including a process by which artificial diamonds are created, and a superior hand-gun.
- The Discovery of a World in the Moon by John Wilkins
- Doctor by Murray Leinster
- Doomsday Eve by Robert Moore Williams
- Dormant by E. NesbitDoomsday Eve (1957 dos), a Post-Holocaust drama in which the world serves as an arena for struggling Supermen.
- Equality by Edward BellamyDormant (1911; vt Rose Royal 1912) is a fantasy-tinged sf novel involving Suspended Animation; the form of Immortality bestowed by the protagonist, who has been awakened after half a century, proves a mixed blessing.
- Eve and the Evangelist by Harry E. RiceEquality continues the arguments of Looking Backward, though almost totally without narrative content, and it is not now read as fiction.
- Farmer by Mack ReynoldsEve and the Evangelist: A Romance of A D 2108 (1908), a Utopia set in distant Near Future America, according to strict financial criteria (see Economics) that limit personal wealth to $50,000; great advances in Transportation are described at some length, as well as intercontinental travel by either by Rocket using a new Power Source or Underground, and Communication with Mars has been achieved. Much is learned from the gigantic, intellectual Martians. During the protagonist's travels across the world, Atlantis rises from the depths, and divulges its secrets, including Telepathy, and perhaps Immortality to boot.
- Fifteen Hundred Miles An Hour by Charles Dixon, published in 1895. (http://www.gutenberg.org/ebooks/49713)"Farmer" (June 1961 Galaxy) is the first of three notable stories which Reynolds set in North Africa, each similarly dealing with the problem of fostering economic and technological development in the teeth of cultural inertia.
- The Gay Rebellion by Robert W. ChambersThe identity of the author seems unclear. Both the British Library and University of Oxford seem to think it is Charles Dixon (1858 - 1926) the British ornithologist. This seems a bit unlikely, as his whole life seems to be about birds, but who knows? This novel purports to be from the manuscripts of a Dr. Hermann, a member of the Royal, the Astronomical, and the Geographical Societies, who disappeared mysteriously and was never seen again.
- The Golden Slave by Poul AndersonThe Gay Rebellion (stories May-September 1911 Hampton's Magazine; coll of linked stories 1913) consists of comical Satires in which women revolt in order to create a new society based on Eugenics, but reform and marry properly.
- His Wisdom, the Defender by Simon Newcomb100 B.C. The Cimbrian hordes galloped across the dawn of history and clashed in screaming battle against the mighty Roman legions. Eodan, son of Chief Boierek, has been on the war campaign for many years. The Cimbrain army has become a hungry homeless pagan tribe. Their sworn enemy, the Romans, they have battled against gloriously. But for all the burning towns, the new-caught women weeping, the wine drunk, the gold lifted, the Cimbri did not find a home. Eodan, the proud young chieftain, had been caught and sold into slavery, his infant son murdered and his beautiful wife, Hwicca, taken as a concubine. But the whips and slave chains could not break the spirit of this fiery pagan giant who fought, seduced and connived his way to a perilous freedom to rescue the woman he loved. A struggle that would make him a lover, pirate, commander, and in the end the struggle would make him a legend!
- Idealia, a Utopian Dream; or, Resthaven by Mrs. Harriet Alfarata ThompsonIn his Edisonade, His Wisdom, the Defender: A Story (1900), future historians tell how a professor discovers a limitless Power Source in 1941, is responsible for the Invention of an Antigravity device, and after creating a private army – equipping it with futuristic armour – takes over the world from the air, establishes a Pax Aeronautica and prohibits war.
- The Last Invasion by Donal Hamilton Haines , Harper & BrothersIdealia: A Utopia Dream; Or, Resthaven (1922 chap), whose protagonist visits a Utopian community for the elderly and the indigent whose features are so exceptionally humane that this domestic Pastoral could readily be understood as occupying an Alternate World.
- LA LÉGENDE DES SIÈCLES, Or The Legend of the Ages by Victor HugoHis two connected sf novels for Young Adult readers, The Last Invasion (1914) and Clearing the Seas; Or, the Last of the Warships (1915), describe various aspects of a moderately futile Future War in which the United States is invaded by the "Blues" (whom E F Bleiler thinks must be Germans), who are eventually driven off, and war itself discounted for good.
- The Lunarian Professor and his Remarkable Revelations Concerning the Earth, the Moon and Mars by James Bradun AlexanderA sci-fi epic poem by Victor Hugo about the development of man.
- The Machine That Floats by Joe GibsonUS author whose sf phantasmagoria, The Lunarian Professor and his Remarkable Revelations Concerning the Earth, the Moon and Mars; Together with an Account of the Cruise of the Sally Ann (1909), might have been excluded from this encyclopedia on the grounds that the insectoid Lunarian pedagogue and all that he surveys turn out to be a dream – were it not that Alexander's imagination, though patently influenced by H G Wells, is too vivid to be ignored. The narrator is told at length, by a visiting six-winged Lunarian, who uses an Antigravity device for travel, about the altruistic three-sexed life on Luna, the future History of Earth (derived from mathematical models, which the professor passes on to the narrator), the Terraforming of Mars (the canals having been constructed to distribute water planet-wide, opening it up for further development), and more.
- The Man Who Rocked the Earth by Arthur Cheney Train and Robert Williams Wood
Science fiction written by a physicist.
- The Man With The Broken Ear by Edmond About
- The Manatitlans by R. Elton SmileHe is best-known for L'Homme à l'Oreille Cassée (1862 2vols; trans anon as The Man with the Broken Ear 1864; new trans Henry Holt 1867; new trans J E Maitland, vt Colonel Fougas' Mistake 1878 2vols); under a further vt, "A New Lease of Life", the tale was included in A New Lease of Life; and, Saving a Daughter's Dowry (coll trans 1880). The novel – which features a Napoleonic colonel in Suspended Animation from 1813 until his resuscitation in 1859 – is a mild Satire on French life and politics, though its main focus is upon the highly energetic Colonel Fougas and his confusion of a young contemporary woman with his beloved of 1813.
- Master of Life and Death by Robert SilverbergIn The Manatitlans; Or, a Record of Recent Scientific Explorations in the Andea Lat Plata, S A (1877), a white expedition travels up the Paraguay River where it discovers a Lost Race descended from the Romans; they in turn introduce the expedition to a race of tiny humanoids (see Great and Small), the Manatitlans, now located here though at times intermittently resident in Europe; their educational system is of interest.
- Memoirs of the Twentieth CenturyA novel dealing with institutionalized measures to combat Overpopulation.
- Men Like Gods by H.G. WellesAn early work of speculative fiction written by Irish writer Samuel Madden. Written in 1733, it takes the form of a series of diplomatic letters written in 1997 and 1998 - 1733
- The Monster by S. M. TenneshawA kind of dramatized continuation of the themes of A Modern Utopia. A group of Earthlings is accidentally transferred via something like Matter Transmission to the world of Utopia (there is some talk of dimensions and adjacent universes, suggesting a Parallel World). There they are welcomed by a race of near Supermen, immensely long-lived (see Immortality), with population growth controlled through Eugenics (Wells had not yet learned to be cautious about this increasingly toxic set of Scientific Errors); they are beneficiaries of high Technology solutions for other problems that may arise, and are constantly stimulated by a state which has withered into a solely educative role (see Education in SF). Most of the visitors (the Imperialist Secretary of State for War Rupert Catskill seems to be a portrait of Winston Churchill, and the bullying preacher resembles G K Chesterton) attempt to conquer this Utopia.

- The Radio Planet by Ralph Milne FarleyThe sequence, at first absurdly boosted by The Argosy as scientifically accurate, is devoted to the adventures of Cabot, mostly on Venus, the Radio Planet. After being accidentally shifted to that planet via Matter Transmitter, Cabot quickly frees its humanoid inhabitants from domination by an ant-like race; after marrying a human princess, he continues his activities ad libitum, though sometimes his son takes over.
- A Republic Without a President and Other Stories by Herbert D. Ward
- Rondah, or, Thirty-Three Years in a Star by Florence Carpenter Dieudonné
- The Scarlet Empire by David MacLean ParryIn her Rondah, or Thirty-Three Years in a Star (1887) the tale's several protagonists travel through the solar system in a mountain which, propelled by explosions, serves as a Spaceship that takes them to a large inhabited Asteroid, where the central figure of the tale becomes king of the native bird-people, who are in fact of vegetable origin, and who are replaced by ferocious elves when the worldlet cools down. Much happens.
- The Secret Martians by Jack SharkeyA young socialist American thinks to commit suicide by jumping into the sea, but awakens in a nightmarish Atlantis, a Lost World Keep protected from the ocean above by a great dome, where – despite a healthy plethora of convenient Inventions – the obsession with regimented equality leads to grotesqueries prophetic of those later dreamt of by Yevgeny Zamiatin in My (ms trans Gregory Zilboorg as We 1924). The use of "letheweed" to Drug the citizens nightly also prefigures Aldous Huxley's Brave New World (1932).

- Sentry Of The Sky by Evelyn E. Smith
- The Silver Menace by Murray Leinster
- The Smoky God, or, A Voyage to the Inner World by Willis George Emerson
- The Social War of 1900 by Simon Landis (PLAY)Set in 1829 in a Hollow-Earth Eden on the John Cleves Symmes model, where a scientifically advanced race of long-lived giants is discovered worshipping its "smoky god", which is the interior sun. Eventually the protagonist, who has arrived via the Arctic Symmes Hole, leaves via the Antarctic, and is thought mad for many years.
- Space Station 1 by Frank Belknap LongPlay adaptation of one of the most notoriously awful science fiction novels ever written (which we've already recorded).
- The Struggle for Empire by Robert William Cole
- Sub-Coelum: A Sky-Built Human World by Addison Peale RussellHis first and best novel, The Struggle for Empire: A Story of the Year 2236 (1900), takes the Future War story to its logical, grim conclusion. The Anglo-Saxon Federation – ostensibly a Utopia with London as its "superb capital" but in truth a class-ridden Dystopia where the rich in their insatiate greed have plundered the planet (see Ecology) – expands ominously into other solar systems in search of raw material to exploit. At this point interstellar warfare breaks out between Earth and a superior race from the Sirius system. The descriptions of space battles, and of an Earth surrounded by a barrage of space torpedoes and mines while scientists struggle to perfect the ultimate Weapon, make it – as Everett F Bleiler argues in Science-Fiction: The Early Years (1990) – the precursor to and equal of many of the Space-Opera stories of the 1930s.
- Thoth: A Romance by J. Shield NicholsonSub-Coelum: A Sky-Built Human World (1893) is a Utopia written, like so many others from this decade, to counter the influence of Edward Bellamy's Looking Backward 2000-1887 (1888). The setting is an unspecified Near Future, in a land with no name, whose inhabitants – who constantly observe and report upon one another – are forcibly conditioned into behaviour patterns the author designates as "pure" (see B F Skinner): Sex is strictly controlled through a rigorous purging of women's freedom of action (see Feminism; Women in SF), with the result that eventually both sexes, now equally chastened, are treated equally; miscegenation and role-reversals such as men freely becoming house-husbands (see Race in SF) are approved of, but within strict principles derived from Eugenics; a tribe of intelligent monkeys (see Apes as Human) is provided with hospital care; because of the translucence of the atmosphere, folk see more clearly here than elsewhere; and honour the earth with plantings.
- Through the Eye of The Needle, by William Dean Howells (sequel to A Traveler from Altruria)A Lost-World novel set around 400 BCE, where a City in the North African desert, settled 2,000 years earlier, has benefited from the scientific advances of its ruler, Thoth the First, who remains in Suspended Animation.
- A Traveler from Altruria by William Dean Howells
- A Trip to Plutonia by Emanuel Haldeman JuliusAltruria, a utopian world that combined the foundations of Christianity and the U.S. Constitution to produce an “ethical socialism” by which society was guided - followed by its sequel, Through the Eye of the Needle [see above] - 1894
- The Troublemakers by George O. Smith
- True History by Lucian
- Ultra: A Story of Pre-Natal Influence by Laura Shellabarger HuntThe earliest known fiction about travelling to outer space, alien life-forms and interplanetary warfare. Written in the 2nd century, the novel has been referred to as "the first known text that could be called science fiction". The work was intended by Lucian as a satire against contemporary and ancient sources, which quote fantastic and mythical events as truth. - 2nd century
- Unveiling a Parallel: A Romance by Alice Ilgenfritz Jones and Ella Merchant
- Utopia Achieved by Herman Hine Brinsmade
- The White Invaders by Ray CummingsUtopia Achieved: A Novel of the Future (1912), depicts a vastly enlarged Near Future New York full of mechanical and cultural marvels, a self-regulating obedient workforce, and free health care. Brinsmade's romantic vew of twentieth-century Transportation – monorails, vast aerial structures that resemble Albert Robida's more exuberant fancies – is perhaps typical of his period, but is unusually inventive.
- Willmoth the Wanderer; or, The Man from Saturn by C.C. Dail
- Wolfbane by C. M. Kornbluth and Frederik PohlWillmoth the Wanderer, Or The Man from Saturn (1890; rev vt Willmoth the Wanderer 1891) is a genuine oddity. Though told with no great skill, its narrative, purporting to be that of Willmoth the Saturnian as told towards the end of his several-million-year lifespan, is an eventful affair. Willmoth proceeds from Saturn to Venus (via Antigravity) and, late in the book, to a prehistoric Earth, where he becomes the Secret Master ruler of the primitive inhabitants, Uplifting them through selective breeding (see Eugenics) into Homo sapiens. The next volume, The Stone Giant: A Story of the Mammoth Cave (1898), moves into a Hollow Earth venue. It is presented as a translation by Willmoth of the memoirs of the prehistoric ruler Wymorian, an 8ft (2.4m) giant and founder of Atlantis, who had been given (by ancient descendants of Willmoth) an elixir of life. Sex is approved of throughout. There is much talk about the ethics of the Immortality experiment, which on the whole is a failure – as, notoriously, was Atlantis. There are some tonal echoes of the titular model for the sequence, Charles Maturin's Melmoth the Wanderer (1820 4vols), but beyond the issue of immortality they are not significant.
- The World Masters by George Chetwynd Griffith - 1903The last novel Kornbluth wrote with Pohl was Wolfbane (October-November Galaxy; 1959; rev by Pohl 1986), in which the Earth is moved out of its orbit by Aliens who capture humans in order to use their bodies in a vast Computer complex; it is a precursor to some of the most ambitious work of authors like Stephen Baxter and Greg Bear.
The World Peril of 1910 by George Chetwynd Griffith - 1907
Yezad: A Romance of the Unknown by George Babcock
- Young Readers Science Fiction Stories by Richard M. ElamA not entirely competent but decidedly complicated tale in which occult and sf modes intermingle. A pilot named Bacon flies too high, and is dashed to Earth by Azrael, only to find that, in something like his astral body, and accompanied by his dark Doppelganger, he has begun a Fantastic Voyage to nearby Stars, where Reincarnation is routine. A Martian mentor demonstrates to Bacon the Utopia that Mars has become. He also describes an earlier drama, in which a group of Martians, fearing that their planet was becoming unlivable, migrate (with digressions) to Earth, losing their records en route, and their culture once landed. Their role as Forerunners to (specifically white) Homo sapiens can now be now revealed. But being a forerunner does not entail Evolution, which Babcock specifically contemned. In a side story, two enfants sauvages disprove Darwin's theory through their instinctive love of God.
- Zalma by T. Mullett Ellis
_________Mullet's sf novel proper, Zalma (1895), exorbitantly traces the protracted Near-Future attempts of the eponymous wrong-side-of-the-bed Russian-Spanish princess to revenge herself on the heir to the throne of England, who has for unclear reasons swiftly annulled their morganatic marriage. Anthrax-bearing Balloons (see also Biology) and evil scientists are brought into play; the tale closes on a possible Europe-wide socialist upheaval.
