Sir Arthur Charles Clarke was one of the most important and influential figures in 20th century science fiction. He spent the first half of his life in England, where he served in World War Two as a radar operator, before emigrating to Ceylon in 1956. He is best known for the novel and movie 2001: A Space Odyssey, which he co-created with the assistance of Stanley Kubrick. Clarke was a graduate of King's College, London where he obtained First Class Honours in Physics and Mathematics. He is past Chairman of the British Interplanetary Society, a member of the Academy of Astronautics, the Royal Astronomical Society, and many other scientific organizations. Author of over fifty books, his numerous awards include the 1961 Kalinga Prize, the AAAS-Westinghouse science writing prize, the Bradford Washburn Award, and the John W. Campbell Award for his novel Rendezvous With Rama. Clarke also won the Nebula Award of the Science Fiction Writers of America in 1972, 1974 and 1979, the Hugo Award of the World Science Fiction Convention in 1974 and 1980, and in 1986 became Grand Master of the Science Fiction Writers of America. He was awarded the CBE in 1989.

Eugène Ionesco, born Eugen Ionescu, was a Romanian playwright and dramatist; one of the foremost playwrights of the Theatre of the Absurd. Beyond ridiculing the most banal situations, Ionesco's plays depict in a tangible way the solitude and insignificance of human existence. Excerpted from Wikipedia.

Zenna Chlarson Henderson was born on November 1, 1917 in the Tucson, Arizona area. She graduated from Arizona State in 1940 with a Bachelors degree in education and worked as a teacher in Arizona throughout her life. She died on May 11, 1983, at the age of 65, in Tucson. Henderson is known almost entirely for short stories about "The People." The People are a race of sensitive, human-looking aliens with psychic abilities who are separated after crash-landing on Earth but come to find each other over a period of many years. Publishing her "People" stories in the leading science fiction magazines of the 50's, 60's and 70's, Henderson became a pioneer in many areas of science fiction literature. She was one of the first female science fiction writers, and was one of an even smaller number who wrote openly as a woman, without using male-sounding pseudonyms or initials (James Tiptree, Jr.; C.L. Moore; etc.). Henderson was one of the first in science fiction to truly take young people seriously and write expressive, mature stories from their point of view. She drew on her experience as a teacher of young people, and was able to bring a rare level of insight to her use of young characters. Henderson's youthful protagonists are neither adults forced into young bodies, nor are they frivolous caricatures. They are very human, complete souls, yet marked by authentic signs of youth and innocence. Interestingly enough, Lois McMaster Bujold and Orson Scott Card, both of whom mention Henderson as an important early influence, have also been among the most successful chroniclers of young people, with such Hugo- and Nebula-award winning novels as Falling Free and Ender's Game. Her books and stories about The People were the basis for the movie The People, 1972, starring William Shatner and Kim Darby. Despite similarities, both Escape to Witch Mountain, 1975, and Return to Witch Mountain, 1978, were a result of books by Alexander Key.

Anthony Boucher (born William Anthony Parker White) (August 21, 1911 – April 29, 1968) was an American science fiction editor and author of mystery novels and short stories. He was particularly influential as an editor. Between 1942 and 1947 he acted as reviewer of mostly mystery fiction for the San Francisco Chronicle. In addition to 'Anthony Boucher,' White also employed the pseudonym 'H. H. Holmes', which was the name of a 19th-century serial killer. In a poll of 17 detective story writers and reviewers, his novel Nine Times Nine was voted as the ninth best locked room mystery of all time. White was born in Oakland, California, and went to college at the University of Southern California. He later received a Masters degree from the University of California, Berkeley. He was admired for his mystery writing but was most noted for his editing, his science fiction anthologies, and his mystery reviews for many years in The New York Times. He was the first English translator of Jorge Luis Borges, translating "El jardín de senderos que se bifurcan" for Ellery Queen's Mystery Magazine. He helped found the Mystery Writers of America in 1946 and, in the same year, was one of the first winners of the MWA's Edgar Award for his mystery reviews in the San Francisco Chronicle. He was founding editor (with J. Francis McComas) of The Magazine of Fantasy & Science Fiction from 1949 to 1958, and was seminal in attempting to make literary quality an important aspect of science fiction. He won the Hugo Award for Best Professional Magazine in 1957 and 1958. Boucher also edited the long-running Best from Fantasy and Science Fiction anthology series, 1952-1959. His short story "The Quest for Saint Aquin" was among the stories selected in 1970 by the Science Fiction Writers of America as one of the best science fiction short stories of all time. As such, it was published in The Science Fiction Hall of Fame Volume One, 1929-1964. Boucher also scripted for radio and was involved in many other activities, as described by William F. Nolan in his essay, "Who Was Anthony Boucher?": The 1940s proved to be a very busy and productive decade for Boucher. In 1945 he launched into a spectacular three-year radio career, plotting more than 100 episodes for The Adventures of Ellery Queen, while also providing plots for the bulk of the Sherlock Holmes radio dramas. By the summer of 1946 he had created his own mystery series for the airwaves, The Casebook of Gregory Hood. ("I was turning out three scripts each week for as many shows," he stated. "It was a mix of hard work and great fun.") Tony left dramatic radio in 1948, "mainly because I was putting in a lot of hours working with J. Francis McComas in creating what soon became The Magazine of Fantasy and Science Fiction. We got it off the ground in 1949 and saw it take hold solidly by 1950. This was a major creative challenge and although I was involved in a lot of other projects, I stayed with F&SF into 1958." Indeed, throughout his years with the magazine, Boucher was certainly involved in "a lot of other projects." Among them: • Supplying the SF and crime markets with new fiction. • Teaching an informal writing class from his home in Berkeley. • Continuing his Sunday mystery columns for the New York Times Book Review. • Functioning as chief critic for Ellery Queen's Mystery Magazine. • Reviewing SF and fantasy (as H.H. Holmes) for the New York Herald Tribune. • Editing True Crime Detective. • Supervising the Mercury Mystery Line and (later) the Dell Great Mystery Library. • Hosting Golden Voices, his series of historical opera recordings for Pacifica Radio. • Serving (in 1951) as president of Mystery Writers of America. In addition to all of this, Tony was a devoted poker player, a political activist, a rabid sport fan (

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.

Algis Budrys was a Lithuanian-American science fiction author, editor, and critic. He was also known under the pen names Frank Mason, Alger Rome, John A. Sentry, William Scarff, Paul Janvier, and Sam & Janet Argo. Called "AJ" by friends, Budrys was born Algirdas Jonas Budrys in Königsberg in East Prussia. He was the son of the consul general of the Lithuanian government, (the pre-World War II government still recognized after the war by the United States, even though the Soviet-sponsored government was in power throughout most of Budrys' life). His family was sent to the United States by the Lithuanian government in 1936 when Budrys was 5 years old. During most of his adult life, he held a captain's commission in the Free Lithuanian Army. Budrys was educated at the University of Miami, and later at Columbia University in New York. His first published science fiction story was The High Purpose, which appeared in Astounding Science Fiction in 1952. Beginning in 1952 Budrys worked as editor and manager for such science fiction publishers as Gnome Press and Galaxy Science Fiction. Some of his science fiction in the 1950s was published under the pen name "John A. Sentry", a reconfigured Anglification of his Lithuanian name. Among his other pseudonyms in the SF magazines of the 1950s and elsewhere, several revived as bylines for vignettes in his magazine Tomorrow Speculative Fiction, is "William Scarff". He also wrote several stories under the names "Ivan Janvier" or "Paul Janvier." He also used the pen name "Alger Rome" in his collaborations with Jerome Bixby. Budrys' 1960 novella Rogue Moon was nominated for a Hugo Award, and was later anthologized in The Science Fiction Hall of Fame, Volume Two (1973). His Cold War science fiction novel Who? was adapted for the screen in 1973. In addition to numerous Hugo Award and Nebula Award nominations, Budrys won the Science Fiction Research Association's 2007 Pilgrim Award for lifetime contributions to speculative fiction scholarship. In 2009, he was the recipient of one of the first three Solstice Awards presented by the SFWA in recognition of his contributions to the field of science fiction. Budrys was married to Edna Duna; they had four sons. He last resided in Evanston, Illinois. He died at home, from metastatic malignant melanoma on June 9, 2008.

Stine attended the University of Colorado in Boulder. Upon his graduation he went to work at White Sands Proving Grounds, first as a civilian scientist and then, from 1955–1957, at the U.S. Naval Ordnance Missile Test Facility as head of the Range Operations Division. Stine and his wife Barbara were friends of author Robert A. Heinlein, who sponsored their wedding, as Harry's parents were dead and Barbara's mother too ill to travel. Several of Heinlein's books are dedicated one or both of them, most particularly Have Space Suit - Will Travel. Stine also wrote science articles for Popular Mechanix. G. Harry Stine also used these alternative names: Lee Correy, Harry Stine, George Harry Stine.
