Books Written by
In 1971 Franz Ingelfinger, the editor of The New England Journal of Medicine, offered Lewis Thomas a monthly column on the journal’s back page. Thomas was 57, a pathologist and medical-school dean, and the essays he sent in were about a thousand words each, unpaid and printed unedited. They were about ants, mitochondria, the atmosphere and what music to send to other planets. Collected as The Lives of a Cell in 1974, they sold more than 250,000 copies in five years and won the National Book Award. He wrote his books while running Memorial Sloan-Kettering and kept writing after a cancer diagnosis in 1988. This guide covers his six key books, in order, and where to begin.

6 Lewis Thomas Books, in Order
The Lives of a Cell
Twenty-nine essays written for The New England Journal of Medicine between 1971 and 1973, on subjects from mitochondria and termite colonies to the atmosphere, which he calls the grandest product of collaboration in nature. The thread running through them is that humans are one part of a connected living system, not its masters. It won the 1975 National Book Award in two categories, Arts and Letters and The Sciences (both shared), and was translated into eleven languages.
The Medusa and the Snail
His second collection from the same column, again mostly first printed in The New England Journal of Medicine. The title essay follows a sea slug and a jellyfish in the Bay of Naples whose lives are so entangled that it is hard to say where one self ends, and others take on worry, enlightenment and the self. Stephen Jay Gould reviewed it on the front page of The New York Times Book Review; the paperback won the 1981 National Book Award for Science.
The Youngest Science
A memoir commissioned for the Alfred P. Sloan Foundation’s series on lives in science. It starts with Thomas as a boy in Flushing, Queens, riding along on his doctor father’s house calls, and moves through Harvard Medical School, an internship at Boston City Hospital, wartime research in the Pacific and his years as a dean. Its argument is that medicine only became a science in the late 1930s, when sulfa drugs and then antibiotics arrived.
Late Night Thoughts on Listening to Mahler’s Ninth Symphony
Twenty-four essays, many first written for Discover magazine, published by Viking in November 1983. The collection opens and closes with nuclear war, which he had come to see as the worst case for the species; in between are essays on psychiatry, lie detectors, having a pacemaker fitted and the uses of basic research. Peter Medawar reviewed it in the London Review of Books.
Et Cetera, Et Cetera
Short essays on etymology, tracing English words back to their Indo-European roots, published by Little, Brown. Thomas treats language the way he treated cells and ant colonies: as a shared system that makes humans a social species.
The Fragile Species
His last book, published by Scribner the year before he died: fourteen essays, many adapted from lectures he gave between 1984 and 1990. The longest sections deal with AIDS and with public health in poor countries; others return to the Gaia hypothesis, his opposition to war and his belief that all life descends from a single bacterium billions of years ago.
In What Order to Read Lewis Thomas
The books do not continue from one another, and each essay stands alone, so you can open any of them anywhere. Publication order still makes sense: the first two collections set out his view of life as cooperation, the 1983 books apply it to medicine and to the threat of nuclear war, and the last two widen it to language and to the species as a whole.
Read The Lives of a Cell first and The Medusa and the Snail straight after, since they come from the same column. The Youngest Science is the only continuous narrative and works well as a break between the essay collections.

How Lewis Thomas Writes: The Biology Watcher
Almost everything Thomas published began as a short magazine piece. The New England Journal of Medicine column, which ran for about ten years from 1971, gave him roughly a thousand words a month and no editor; later essays were written for Discover or delivered as lectures. The books are those pieces gathered up, which is why they can be read in any order and why each essay usually turns on a single observation.
His subject is cooperation. Mitochondria living inside our cells as former free-living bacteria, ant colonies that behave like one animal, the atmosphere as a membrane around the planet: he keeps returning to the idea that living things are joined rather than separate, and that humans are part of nature rather than in charge of it. In the 1980s the same lens turned darker, onto nuclear weapons, which he saw as the one thing that could undo it.
He writes as a working scientist, with real data, but in the first person and with a light, conversational tone that reviewers compared to Montaigne. John Updike reviewed The Lives of a Cell in The New Yorker, Joyce Carol Oates in The New York Times Book Review, and Stephen Jay Gould reviewed two of his later books. Word origins are a constant: many essays start from where a word came from, and in Et Cetera, Et Cetera that habit became a whole book.
