Isaac Asimov was a Russian-born, American author, a professor of biochemistry, and a highly successful writer, best known for his works of science fiction and for his popular science books. Professor Asimov is generally considered one of the most prolific writers of all time, having written or edited more than 500 books and an estimated 90,000 letters and postcards. He has works published in nine of the ten major categories of the Dewey Decimal System (lacking only an entry in the 100s category of Philosophy). Asimov is widely considered a master of the science-fiction genre and, along with Robert A. Heinlein and Arthur C. Clarke, was considered one of the "Big Three" science-fiction writers during his lifetime. Asimov's most famous work is the Foundation Series; his other major series are the Galactic Empire series and the Robot series, both of which he later tied into the same fictional universe as the Foundation Series to create a unified "future history" for his stories much like those pioneered by Robert A. Heinlein and previously produced by Cordwainer Smith and Poul Anderson. He penned numerous short stories, among them "Nightfall", which in 1964 was voted by the Science Fiction Writers of America the best short science fiction story of all time, a title many still honor. He also wrote mysteries and fantasy, as well as a great amount of nonfiction. Asimov wrote the Lucky Starr series of juvenile science-fiction novels using the pen name Paul French. Most of Asimov's popularized science books explain scientific concepts in a historical way, going as far back as possible to a time when the science in question was at its simplest stage. He often provides nationalities, birth dates, and death dates for the scientists he mentions, as well as etymologies and pronunciation guides for technical terms. Examples include his Guide to Science, the three volume set Understanding Physics, and Asimov's Chronology of Science and Discovery. Asimov was a long-time member and Vice President of Mensa International, albeit reluctantly; he described some members of that organization as "brain-proud and aggressive about their IQs" He took more joy in being president of the American Humanist Association. The asteroid 5020 Asimov, the magazine Asimov's Science Fiction, a Brooklyn, NY elementary school, and two different Isaac Asimov Awards are named in his honor.

Works of American science-fiction writer Robert Anson Heinlein include Stranger in a Strange Land (1961) and The Moon Is a Harsh Mistress (1966). People often call this novelist "the dean of science fiction writers", one of the most popular, influential, and controversial authors of "hard science fiction." He set a high standard for science and engineering plausibility and helped to raise the standards of literary quality of the genre. He was the first science-fiction writer to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s. He was also among the first authors of bestselling, novel-length science fiction in the modern, mass-market era. Also wrote under Pen names: Anson McDonald, Lyle Monroe, Caleb Saunders, John Riverside and Simon York.

Lester del Rey was an American science fiction author and editor. Del Rey is especially famous for his juvenile novels such as those which are part of the Winston Science Fiction series, and for Del Rey Books, the fantasy and science fiction branch of Ballantine Books edited by Lester del Rey and his fourth wife Judy-Lynn del Rey. Also published as: Philip St. John Eric van Lihn Erik van Lhin Kenneth Wright Edson McCann (with Frederik Pohl)

James Benjamin Blish was an American author of fantasy and science fiction. Blish also wrote literary criticism of science fiction using the pen-name William Atheling Jr. In the late 1930's to the early 1940's, Blish was a member of the Futurians. Blish trained as a biologist at Rutgers and Columbia University, and spent 1942–1944 as a medical technician in the U.S. Army. After the war he became the science editor for the Pfizer pharmaceutical company. His first published story appeared in 1940, and his writing career progressed until he gave up his job to become a professional writer. He is credited with coining the term gas giant, in the story "Solar Plexus" as it appeared in the anthology Beyond Human Ken, edited by Judith Merril. (The story was originally published in 1941, but that version did not contain the term; Blish apparently added it in a rewrite done for the anthology, which was first published in 1952.) Blish was married to the literary agent Virginia Kidd from 1947 to 1963. From 1962 to 1968, he worked for the Tobacco Institute. Between 1967 and his death from lung cancer in 1975, Blish became the first author to write short story collections based upon the classic TV series Star Trek. In total, Blish wrote 11 volumes of short stories adapted from episodes of the 1960s TV series, as well as an original novel, Spock Must Die! in 1970 — the first original novel for adult readers based upon the series (since then hundreds more have been published). He died midway through writing Star Trek 12; his wife, J.A. Lawrence, completed the book, and later completed the adaptations in the volume Mudd's Angels. Blish lived in Milford, Pennsylvania at Arrowhead until the mid-1960s. In 1968, Blish emigrated to England, and lived in Oxford until his death in 1975. He is buried in Holywell Cemetery, Oxford, near the grave of Kenneth Grahame. His name in Greek is Τζέημς Μπλις"

Alfred Elton van Vogt was a Canadian-born science fiction author regarded by some as one of the most popular and complex science fiction writers of the mid-twentieth century—the "Golden Age" of the genre. van Vogt was born to Russian Mennonite family. Until he was four years old, van Vogt and his family spoke only a dialect of Low German in the home. He began his writing career with 'true story' romances, but then moved to writing science fiction, a field he identified with. His first story was Black Destroyer, that appeared as the front cover story for the July 1939 edtion of the popular "Astounding Science Fiction" magazine.

Theodore Sturgeon (1918–1985) is considered one of the godfathers of contemporary science fiction and dark fantasy. The author of numerous acclaimed short stories and novels, among them the classics More Than Human, Venus Plus X, and To Marry Medusa, Sturgeon also wrote for television and holds among his credits two episodes of the original 1960s Star Trek series, for which he created the Vulcan mating ritual and the expression “Live long and prosper.” He is also credited as the inspiration for Kurt Vonnegut’s recurring fictional character Kilgore Trout. Sturgeon is the recipient of the Hugo Award, the Nebula Award, and the International Fantasy Award. In 2000, he was posthumously honored with a World Fantasy Award for Life Achievement.

Alfred Bester was an American science fiction author, TV and radio scriptwriter, magazine editor and scripter for comic strips and comic books. Though successful in all these fields, he is best remembered for his science fiction, including The Demolished Man, winner of the inaugural Hugo Award in 1953, a story about murder in a future society where the police are telepathic, and The Stars My Destination, a 1956 SF classic about a man bent on revenge in a world where people can teleport, that inspired numerous authors in the genre and is considered an early precursor to the cyberpunk movement in the 1980s.
