There is real evidence Churchill used the line around 1952: Kay Halle, who knew him well, printed it in Irrepressible Churchill in a section dated 1952 and labelled it “Ear-witness”, meaning a mutual friend reported it from him. But the joke was already circulating nine years earlier, unsigned, in Esar’s Comic Dictionary of 1943 — which is why Quote Investigator concludes it is “unlikely that Churchill coined this joke”. The 1943 wording also differs: it reads “can’t change his opinion”, and the “mind” version only shows up in newspapers from 1949.
“Fanatic: One Who Can't Change His Mind and Won't Change the Subject” Anonymous — earliest documented in Esar's Comic Dictionary (1943), p. 101, as "One who can't change his opinion and won't change the subject"; Churchill was reported using it around 1952 but did not coin it — traced by Quotle.info · Verbatim: “Fanatic: One who can't change his opinion and won't change the subject.”

fanatic. A person who redoubles his efforts after having forgotten his aims. One who can’t change his opinion and won’t change the subject.
Esar’s Comic Dictionary, 1943, p. 101
Both of the 1943 book’s definitions for “fanatic”, as Quote Investigator transcribes them from the page it verified on paper. Neither carries an attribution.
Quote Investigator’s investigation ↗ is the anchor. Its conclusion: “there is evidence that Winston Churchill used this quip around 1952 based on Kay Halle’s book; however, the expression was already in circulation by 1943. Hence, it is unlikely that Churchill coined this joke.”
The 1943 printing is cited as Esar’s Comic Dictionary, page 101, Harvest House, New York, marked “Verified on paper” by QI. We confirmed the book exists — the Internet Archive holds a 1943 scan ↗ — but it is lending-restricted and returns an authorisation error, so the page reading is QI’s, not ours.
QI tracks the wording drift in dated newspaper citations: “opinion” in the Oakland Tribune (1945), Reader’s Digest (1949) and The Seattle Times (1949); the “mind” form from The Attica News in August 1949 and the Princeton Alumni Weekly in February 1951. The Churchill ascriptions follow in 1952, including The Christian Science Monitor of 24 May 1952.
We checked Wikiquote’s Churchill page ↗ and it does not carry this line at all, in any section — so there is no Wikiquote finding here to agree or disagree with. That is our own observation, not a citation.
No rights claim is made here, because no author can be named. The earliest printing anyone has produced is the 1943 Comic Dictionary, which falls after the 1931 United States public-domain cut-off, and the wording in circulation today is a later newspaper variant of it. quotle.info therefore makes no public-domain claim for this line.

Fact-check
Often misattributed
This one is unusual: the famous name attached to it probably did say it. He just did not invent it, and two other names have been attached along the way.
~
The popular creditWinston Churchill Repeated it, did not coin it
Kay Halle’s Irrepressible Churchill records the line in a section dated 1952 on an “Ear-witness” basis, and newspapers were crediting him by May 1952. But QI shows it in print in 1943 ↗, nine years earlier and unsigned, so the coinage is not his.
✕
A stray creditAmbrose Bierce No evidence
The quotation collector Bennett Cerf printed the definition in his syndicated column in 1964 and credited Bierce, who died around 1914. QI calls the ascription “oddly different” ↗ and offers nothing to support it.
~
The earliest printerEvan Esar Compiler, not author
His 1943 dictionary is the earliest known appearance, but QI notes ↗ that “no attribution was provided by Esar”, and Esar printed his definitions as material of popular origin. Being first in print is not authorship.
✓Quote Investigator’s verdict ↗: the quip was circulating by 1943 and Churchill did not originate it. The honest credit is unknown — with Churchill as a documented user, not the author.
Context
Why it mattered
The joke works because it defines a fanatic by behaviour rather than belief: not someone who is wrong, but someone with whom conversation has become impossible. That is a thoroughly modern complaint, and it is why the line has outlived every name attached to it.
Churchill is the ideal host for it. He really did deal in this kind of compressed, slightly cruel wit, so the attribution passes the plausibility test that stops most people checking — and a friend genuinely did report hearing him use it. What the record shows is a man repeating a good joke, which is the most ordinary thing in the world and the hardest thing to prove he did not invent.
Not someone who is wrong, but someone with whom conversation has become impossible.

1874–1965 · British statesman, writer and 1953 Nobel laureate in Literature
Sir Winston Churchill (1874–1965) was a British statesman, soldier and writer, Prime Minister through the Second World War and again in the early 1950s, and winner of the Nobel Prize in Literature in 1953. He was a genuine wit and a prolific phrase-maker, which is precisely why he is one of the internet’s largest magnets for jokes he never wrote. In this case a friend did report hearing him use the line — around 1952, nine years after it first appeared in print without his name.
