Isaac Asimov: Robots, Foundation & the Three Laws
Chapter 9 · Asimov the Essayist & Popularizer of Science
A Column That Ran for Thirty-Three Years
Asimov wrote a monthly science essay column for The Magazine of Fantasy & Science Fiction, running from November 1958 until late 1991 — his declining health prevented him from finishing what would have been his 400th essay before his death in April 1992. He completed 399 essays in total, published almost without interruption across roughly thirty-three years — one of the longest unbroken nonfiction series of its kind.
Reference Works That Explained Entire Fields
Originated as The Intelligent Man's Guide to Science (1960), retitled and revised across later editions.
Published 1964, originally covering roughly 1,000 scientist biographies, later expanded past 1,500 in revised editions — organized chronologically, from Imhotep to Stephen Hawking.
A real, comprehensive reference tracing the history of scientific discovery.
A three-volume popular introduction to physics.
Beyond Science: Guides to the Bible and Shakespeare
Asimov's Guide to the Bible was published in two volumes (1968 and 1969), later combined into a single 1,296-page edition in 1981 — following the King James Version's own book order, with maps and historical and geographical context, written for a reader assumed to have no prior background at all. Asimov's Guide to Shakespeare followed the same explainer-guide approach.
A Philosophy of Explaining, Not Just Informing
Asimov described himself, in his own words, as "one of the most versatile writers in the world, and the greatest popularizer of many subjects." He separately noted that his F&SF column was the one place he never had to assume complete ignorance of the subject in his own readers — implying, by contrast, that his other popular science writing was deliberately aimed at a general audience with no assumed background at all.
An Estimated 90,000 Letters
Asimov is widely credited with writing an estimated 90,000 letters and postcards over his lifetime — a figure that appears consistently in mainstream references, though without a clear, precisely audited primary source behind the exact number. Treat it as a genuine, widely repeated estimate of the sheer scale of his correspondence, not a precisely counted figure.
The Scale of It All
Chapter 1 already covered the headline figure — 500+ books, spanning nine of the ten Dewey Decimal categories. By 1992, his non-fiction titles alone numbered in the hundreds, widely described as lucid, comprehensive popularizations spanning essentially every field of science.
Fiction and Non-Fiction, Side by Side
| Fiction | Non-Fiction | |
|---|---|---|
| Signature works | I, Robot, the Foundation trilogy | Asimov's Guide to Science, the Biographical Encyclopedia |
| Longest-running project | The Robot/Foundation merge, spanning decades | The F&SF column, 399 essays over 33 years |
| Real range | Robots, psychohistory, galactic empires | Physics, biography, the Bible, Shakespeare |
Questions to Sit With
Asimov wrote guides to the Bible and Shakespeare despite having no formal training in either. Do you think genuine expertise is required to write a good popular explainer, or is a talent for clear explanation itself the more important skill?
A 33-year monthly column, almost never missing an issue, is a real feat of sustained discipline. What do you think it takes to maintain that kind of consistency across decades, on top of an already enormous fiction career?
The "90,000 letters" figure is widely repeated but not precisely sourced. Does a number like this losing its precision under scrutiny change how impressive you find the underlying claim, or does the general scale still speak for itself?
Quick Reference — Chapter 9
- His Fantasy & Science Fiction column ran November 1958–1991, 399 essays over ~33 years, winning a special 1963 Hugo
- Major reference works — Asimov's Guide to Science, the Biographical Encyclopedia of Science and Technology, the Chronology of Science and Discovery, Understanding Physics
- Guides to the Bible (1968/69) and Shakespeare extended his range well beyond his own biochemistry training
- His own stated self-description as a versatile popularizer is real; the popular "any interested layman" phrasing is a fair paraphrase, not an independently verified direct quote
- An estimated, widely-repeated (but not precisely audited) 90,000 letters and postcards over his lifetime
