Overview Asimov's career can be divided into several periods. His early career, dominated by science fiction, began with short stories in 1939 and novels in 1950. This lasted until about 1958, all but ending after publication of
The Naked Sun (1957). He began publishing nonfiction as co-author of a college-level textbook called
Biochemistry and Human Metabolism. Following the brief orbit of the first human-made satellite
Sputnik I by the USSR in 1957, he wrote more nonfiction, particularly
popular science books, and less science fiction. Over the next quarter-century, he wrote only four science fiction novels, and 120 nonfiction books. Starting in 1982, the second half of his science fiction career began with the publication of ''
Foundation's Edge''. From then until his death, Asimov published several more sequels and prequels to his existing novels, tying them together in a way he had not originally anticipated, making a unified series. There are many inconsistencies in this unification, especially in his earlier stories.
Doubleday and
Houghton Mifflin published about 60% of his work up to 1969, Asimov stating that "both represent a father image". Asimov believed his most enduring contributions would be his "
Three Laws of Robotics" and the
Foundation series. The
Oxford English Dictionary credits his science fiction for introducing into the English language the words "
robotics", "
positronic" (an entirely fictional technology), and "
psychohistory" (which is also used for a
different study on historical motivations). Asimov coined the term "robotics" without suspecting that it might be an original word; at the time, he believed it was simply the natural analogue of words such as
mechanics and
hydraulics, but for
robots. Unlike his word "psychohistory", the word "robotics" continues in mainstream technical use with Asimov's original definition.
Star Trek: The Next Generation featured
androids with "
positronic brains" and the first-season episode "
Datalore" called the positronic brain "Asimov's dream". Asimov was so prolific and diverse in his writing that his books span all major categories of the
Dewey Decimal Classification except for category 100,
philosophy and
psychology. and forewords for the books
The Humanist Way (1988) and
In Pursuit of Truth (1982), which were classified in the 100s category, but none of his own books were classified in that category. According to
UNESCO's
Index Translationum database, Asimov is the world's 24th-most-translated author.
Science fiction in 1951. The novel was issued in book form later that year as The Stars Like Dust''.
on the cover of the October 1953 issue of Galaxy Science Fiction'', illustrated by
Ed Emshwiller , the only Asimov story to appear in
Weird Tales Asimov became a science fiction fan in 1929, when he began reading the
pulp magazines sold in his family's candy store. At first his father forbade reading pulps until Asimov persuaded him that because the
science fiction magazines had "Science" in the title, they must be educational. At age 18 he joined the
Futurians science fiction fan club, where he made friends who went on to become science fiction writers or editors. Asimov began writing at the age of 11, imitating
The Rover Boys with eight chapters of
The Greenville Chums at College. His father bought him a used typewriter at age 16. His first published work was a humorous item on the birth of his brother for Boys High School's literary journal in 1934. In May 1937 he first thought of writing professionally, and began writing his first science fiction story, "Cosmic Corkscrew" (now lost), that year. On May 17, 1938, puzzled by a change in the schedule of
Astounding Science Fiction, Asimov visited its publisher
Street & Smith Publications. Inspired by the visit, he finished the story on June 19, 1938, and personally submitted it to
Astounding editor
John W. Campbell two days later. Campbell met with Asimov for more than an hour and promised to read the story himself. Two days later he received a detailed rejection letter. This was the first of what became almost weekly meetings with the editor while Asimov lived in New York, until moving to Boston in 1949; Campbell had a strong formative influence on Asimov and became a personal friend. By the end of the month, Asimov completed a second story, "
Stowaway". Campbell rejected it on July 22 but—in "the nicest possible letter you could imagine"—encouraged him to continue writing, promising that Asimov might sell his work after another year and a dozen stories of practice. On October 21, 1938, he sold the third story he finished, "
Marooned Off Vesta", to
Amazing Stories, edited by
Raymond A. Palmer, and it appeared in the March 1939 issue. Asimov was paid $64 (), or one cent a word. Two more stories appeared that year, "
The Weapon Too Dreadful to Use" in the May
Amazing and "
Trends" in the July
Astounding, the issue fans later selected as the start of the
Golden Age of Science Fiction. For 1940,
ISFDB catalogs seven stories in four different pulp magazines, including one in
Astounding. Through July 29, 1940, Asimov wrote 22 stories in 25 months, of which 13 were published; he wrote in 1972 that from that date he never wrote a science fiction story that was not published (except for two "special cases"). By 1941 Asimov was famous enough that
Donald Wollheim told him that he purchased "
The Secret Sense" for a new magazine only because of his name, and the December 1940 issue of
Astonishing—featuring Asimov's name in bold—was the first magazine to base
cover art on his work, but Asimov later said that neither he nor anyone else—except perhaps Campbell—considered him better than an often published "third rater". Based on a conversation with Campbell, Asimov wrote "
Nightfall", his 32nd story, in March and April 1941, and
Astounding published it in September 1941. In 1968 the
Science Fiction Writers of America voted "Nightfall" the best science fiction short story ever written. In
Nightfall and Other Stories Asimov wrote, "The writing of 'Nightfall' was a watershed in my professional career ... I was suddenly taken seriously and the world of science fiction became aware that I existed. As the years passed, in fact, it became evident that I had written a 'classic'." "Nightfall" is an archetypal example of
social science fiction, a term he created to describe a new trend in the 1940s, led by authors including him and Heinlein, away from
gadgets and
space opera and toward speculation about the
human condition. After writing "
Victory Unintentional" in January and February 1942, Asimov did not write another story for a year. He expected to make chemistry his career, and was paid $2,600 annually at the Philadelphia Navy Yard, enough to marry his girlfriend; he did not expect to make much more from writing than the $1,788.50 he had earned from the 28 stories he had already sold over four years. Asimov left science fiction fandom and no longer read new magazines, and might have left the writing profession had not Heinlein and de Camp been his coworkers at the Navy Yard and previously sold stories continued to appear. In 1942, Asimov published the first of his
Foundation stories—later collected in the
Foundation trilogy:
Foundation (1951),
Foundation and Empire (1952), and
Second Foundation (1953). The books describe the fall of a vast
interstellar empire and the establishment of its eventual successor. They feature his fictional science of
psychohistory, whose theories could predict the future course of history according to dynamical laws regarding the statistical analysis of mass human actions. Campbell raised his rate per word,
Orson Welles purchased rights to "
Evidence", and anthologies reprinted his stories. By the end of the war Asimov was earning as a writer an amount equal to half of his Navy Yard salary, even after a raise, but Asimov still did not believe that writing could support him, his wife, and future children. His
"positronic" robot stories—many of which were collected in
I, Robot (1950)—were begun at about the same time. They promulgated a set of rules of
ethics for robots (see
Three Laws of Robotics) and intelligent machines that greatly influenced other writers and thinkers in their treatment of the subject. Asimov notes in his introduction to the short story collection
The Complete Robot (1982) that he was largely inspired by the tendency of robots up to that time to fall consistently into a
Frankenstein plot in which they destroyed their creators. The
Robot series has led to film adaptations. With Asimov's collaboration, in about 1977,
Harlan Ellison wrote a screenplay of
I, Robot that Asimov hoped would lead to "the first really adult, complex, worthwhile
science fiction film ever made". The screenplay has never been filmed and was eventually published in book form in 1994. The 2004 movie
I, Robot, starring
Will Smith, was based on an unrelated script by
Jeff Vintar titled
Hardwired, with Asimov's ideas incorporated later after the rights to Asimov's title were acquired. (The title was not original to Asimov but had previously been used for
a story by
Eando Binder.) Also, one of Asimov's robot short stories, "
The Bicentennial Man", was expanded into a novel
The Positronic Man by Asimov and
Robert Silverberg, and this was adapted into the 1999 movie
Bicentennial Man, starring
Robin Williams. and they along with the
Robot series are his most famous science fiction. Besides movies, his
Foundation and
Robot stories have inspired other derivative works of science fiction literature, many by well-known and established authors such as
Roger MacBride Allen,
Greg Bear,
Gregory Benford,
David Brin, and
Donald Kingsbury. At least some of these appear to have been done with the blessing of, or at the request of, Asimov's widow,
Janet Asimov. In 1948, he also wrote a spoof chemistry article, "
The Endochronic Properties of Resublimated Thiotimoline". At the time, Asimov was preparing his own doctoral
dissertation, which would include an oral examination. Fearing a prejudicial reaction from his graduate school evaluation board at
Columbia University, Asimov asked his editor that it be released under a pseudonym. When it nevertheless appeared under his own name, Asimov grew concerned that his doctoral examiners might think he wasn't taking science seriously. At the end of the examination, one evaluator turned to him, smiling, and said, "What can you tell us, Mr. Asimov, about the thermodynamic properties of the compound known as thiotimoline". Laughing hysterically with relief, Asimov had to be led out of the room. After a five-minute wait, he was summoned back into the room and congratulated as "Dr. Asimov". Demand for science fiction greatly increased during the 1950s, making it possible for a genre author to write full-time. In 1949, book publisher
Doubleday's science fiction editor Walter I. Bradbury accepted Asimov's unpublished "Grow Old with Me" (40,000 words), but requested that it be extended to a full novel of 70,000 words. The book appeared under the Doubleday imprint in January 1950 with the title of
Pebble in the Sky. Doubleday published five more original science fiction novels by Asimov in the 1950s, along with the six juvenile
Lucky Starr novels, the latter under the pseudonym "Paul French". Doubleday also published collections of Asimov's short stories, beginning with
The Martian Way and Other Stories in 1955. The early 1950s also saw
Gnome Press publish one collection of Asimov's positronic robot stories as
I, Robot and his
Foundation stories and novelettes as the three books of the
Foundation trilogy. More positronic robot stories were republished in book form as
The Rest of the Robots. Book publishers and the magazines
Galaxy and
Fantasy & Science Fiction ended Asimov's dependence on
Astounding. He later described the era as his "'mature' period". Asimov's "
The Last Question" (1956), on the ability of humankind to cope with and potentially reverse the process of
entropy, was his personal favorite story. In 1972, his stand-alone novel
The Gods Themselves was published to general acclaim, winning Best Novel in the
Hugo,
Nebula, In December 1974, former
Beatle Paul McCartney approached Asimov and asked him to write the screenplay for a science-fiction movie musical. McCartney had a vague idea for the plot and a small scrap of dialogue, about a rock band whose members discover they are being impersonated by extraterrestrials. The band and their impostors would likely be played by McCartney's group
Wings, then at the height of their career. Though not generally a fan of rock music, Asimov was intrigued by the idea and quickly produced a treatment outline of the story adhering to McCartney's overall idea but omitting McCartney's scrap of dialogue. McCartney rejected it, and the treatment now exists only in the Boston University archives. Asimov said in 1969 that he had "the happiest of all my associations with science fiction magazines" with
Fantasy & Science Fiction; "I have no complaints about
Astounding,
Galaxy, or any of the rest, heaven knows, but
F&SF has become something special to me". Beginning in 1977, Asimov lent his name to ''Isaac Asimov's Science Fiction Magazine
(now Asimov's Science Fiction) and wrote an editorial for each issue. There was also a short-lived Asimov's SF Adventure Magazine and a companion Asimov's Science Fiction Anthology
reprint series, published as magazines (in the same manner as the stablemates Ellery Queen's Mystery Magazines and Alfred Hitchcock's Mystery Magazine''s "anthologies"). Due to pressure by fans on Asimov to write another book in his
Foundation series, He also helped
Leonard Nimoy fleshing out the premise of the science fiction comic
Primortals (1995–1997).
Popular science Asimov and two colleagues published a textbook in 1949, with two more editions by 1969. During the late 1950s and 1960s, Asimov substantially decreased his fiction output (he published only four adult novels between 1957's
The Naked Sun and 1982's ''
Foundation's Edge, two of which were mysteries). He greatly increased his nonfiction production, writing mostly on science topics; the launch of Sputnik in 1957 engendered public concern over a "science gap". Asimov explained in The Rest of the Robots'' that he had been unable to write substantial fiction since the summer of 1958, and observers understood him as saying that his fiction career had ended, or was permanently interrupted. Asimov recalled in 1969 that "the United States went into a kind of tizzy, and so did I. I was overcome by the ardent desire to write popular science for an America that might be in great danger through its neglect of science, and a number of publishers got an equally ardent desire to publish popular science for the same reason".
Fantasy and Science Fiction invited Asimov to continue his regular nonfiction column, begun in the now-folded bimonthly companion magazine
Venture Science Fiction Magazine. The first of 399 monthly
F&SF columns appeared in November 1958 and they continued until his terminal illness. These columns, periodically collected into books by Doubleday, gave Asimov a reputation as a "Great Explainer" of science; he described them as his only popular science writing in which he never had to assume complete ignorance of the subjects on the part of his readers. The column was ostensibly dedicated to popular science but Asimov had complete editorial freedom, and wrote about contemporary social issues in essays such as "Thinking About Thinking" and "Knock Plastic!". In 1975 he wrote of these essays: "I get more pleasure out of them than out of any other writing assignment." Asimov's first wide-ranging reference work, ''
The Intelligent Man's Guide to Science (1960), was nominated for a National Book Award, and in 1963 he won a Hugo Award—his first—for his essays for F&SF''. The popularity of his science books and the income he derived from them allowed him to give up most academic responsibilities and become a full-time
freelance writer. He encouraged other science fiction writers to write popular science, stating in 1967 that "the knowledgeable, skillful science writer is worth his weight in contracts", with "twice as much work as he can possibly handle". The great variety of information covered in Asimov's writings prompted
Kurt Vonnegut to ask, "How does it feel to know everything?" Asimov replied that he only knew how it felt to have the 'reputation' of omniscience: "Uneasy".
Floyd C. Gale said that "Asimov has a rare talent. He can make your mental mouth water over dry facts", and "science fiction's loss has been science popularization's gain". Asimov said that "Of all the writing I do, fiction, non-fiction, adult, or juvenile, these
F & SF articles are by far the most fun". He regretted, however, that he had less time for fiction—causing dissatisfied readers to send him letters of complaint—stating in 1969 that "In the last ten years, I've done a couple of novels, some collections, a dozen or so stories, but that's
nothing". In his essay "To Tell a Chemist" (1965), Asimov proposed a simple
shibboleth for distinguishing chemists from non-chemists: ask the person to read the word "unionized". Chemists, he noted, will read
un-
ionized (electrically neutral), while non-chemists will read
union-ized (belonging to a trade union).
Coined terms Asimov coined the term "
robotics" in his May 1941 story "
Liar!", though he later remarked that he believed then that he was merely using an existing word, as he stated in
Gold ("The Robot Chronicles"). While acknowledging the Oxford Dictionary reference, he incorrectly states that the word was first printed about one third of the way down the first column of page 100 in the March 1942 issue of
Astounding Science Fiction – the printing of his short story "
Runaround". In the same story, Asimov also coined the term "positronic" (the counterpart to "electronic" for
positrons). Asimov coined the term "
psychohistory" in his
Foundation stories to name a fictional branch of science which combines
history,
sociology, and
mathematical statistics to make general predictions about the future behavior of very large groups of people, such as the
Galactic Empire. Asimov said later that he should have called it psychosociology. It was first introduced in the five short stories (1942–1944) which would later be collected as the 1951
fix-up novel
Foundation. Somewhat later, the term "
psychohistory" was applied by others to research of the effects of psychology on history.
Other writings In addition to his interest in science, Asimov was interested in history. Starting in the 1960s, he wrote 18 popular history books, including
The Greeks: A Great Adventure (1965),
The Roman Republic (1966),
The Roman Empire (1967),
The Egyptians (1967),
The Near East: 10,000 Years of History (1968), and ''
Asimov's Chronology of the World'' (1991). He published ''
Asimov's Guide to the Bible in two volumes—covering the Old Testament in 1967 and the New Testament in 1969—and then combined them into one 1,300-page volume in 1981. Complete with maps and tables, the guide goes through the books of the Bible in order, explaining the history of each one and the political influences that affected it, as well as biographical information about the important characters. His interest in literature manifested itself in several annotations of literary works, including Asimov's Guide to Shakespeare (1970), Asimov's Annotated Don Juan
(1972), Asimov's Annotated Paradise Lost
(1974), and The Annotated Gulliver's Travels'' (1980). Asimov was also a noted mystery author and a frequent contributor to ''Ellery Queen's Mystery Magazine''. He began by writing science fiction mysteries such as his Wendell Urth stories, but soon moved on to writing "pure" mysteries. He published two full-length mystery novels, and wrote 66 stories about the
Black Widowers, a group of men who met monthly for dinner, conversation, and a puzzle. He got the idea for the Widowers from his own association in a stag group called the Trap Door Spiders, and all of the main characters (with the exception of the waiter, Henry, who he admitted resembled Wodehouse's Jeeves) were modeled after his closest friends. A parody of the Black Widowers, "An Evening with the White Divorcés," was written by author, critic, and librarian Jon L. Breen. Asimov joked, "all I can do ... is to wait until I catch him in a dark alley, someday." Toward the end of his life, Asimov published a series of collections of
limericks, mostly written by himself, starting with
Lecherous Limericks, which appeared in 1975.
Limericks: Too Gross, whose title displays Asimov's love of
puns, contains 144 limericks by Asimov and an equal number by
John Ciardi. He even created a slim volume of
Sherlockian limericks. Asimov featured
Yiddish humor in
Azazel, The Two Centimeter Demon. The two main characters, both Jewish, talk over dinner, or lunch, or breakfast, about anecdotes of "George" and his friend Azazel. Asimov's
Treasury of Humor is both a working joke book and a treatise propounding his views on
humor theory. According to Asimov, the most essential element of humor is an abrupt change in point of view, one that suddenly shifts focus from the important to the trivial, or from the sublime to the ridiculous. Particularly in his later years, Asimov to some extent cultivated an image of himself as an amiable lecher. In 1971, as a response to the popularity of sexual guidebooks such as
The Sensuous Woman (by "J") and
The Sensuous Man (by "M"), Asimov published
The Sensuous Dirty Old Man under the byline "Dr. 'A (although his full name was printed on the paperback edition, first published 1972). However, by 2016, Asimov's habit of groping women was seen as
sexual harassment and came under criticism, and was cited as an early example of inappropriate behavior that can occur at science fiction conventions. Asimov published
three volumes of autobiography.
In Memory Yet Green (1979) and
In Joy Still Felt (1980) cover his life up to 1978. The third volume,
I. Asimov: A Memoir (1994), covered his whole life (rather than following on from where the second volume left off). The epilogue was written by his widow
Janet Asimov after his death. The book won a
Hugo Award in 1995. Janet Asimov edited ''
It's Been a Good Life (2002), a condensed version of his three autobiographies. He also published three volumes of retrospectives of his writing, Opus 100 (1969), Opus 200 (1979), and Opus 300'' (1984). In 1987, the Asimovs co-wrote
How to Enjoy Writing: A Book of Aid and Comfort. In it they offer advice on how to maintain a positive attitude and stay productive when dealing with discouragement, distractions, rejection, and thick-headed editors. The book includes many quotations, essays, anecdotes, and husband-wife dialogues about the ups and downs of being an author. Asimov and
Star Trek creator
Gene Roddenberry developed a unique relationship during
Star Treks initial launch in the late 1960s. Asimov wrote a critical essay on
Star Treks scientific accuracy for
TV Guide magazine. Roddenberry retorted respectfully with a personal letter explaining the limitations of accuracy when writing a weekly series. Asimov corrected himself with a follow-up essay to
TV Guide claiming that despite its inaccuracies,
Star Trek was a fresh and intellectually challenging
science fiction television show. The two remained friends to the point where Asimov even served as an advisor on a number of
Star Trek projects. In 1973, Asimov published a proposal for
calendar reform, called the World Season Calendar. It divides the year into four seasons (named A–D) of 13 weeks (91 days) each. This allows days to be named, e.g., "D-73" instead of December 1 (due to December 1 being the 73rd day of the 4th quarter). An extra 'year day' is added for a total of 365 days.
Awards and recognition Asimov won more than a dozen annual awards for particular works of science fiction and a half-dozen lifetime awards. He also received 14
