16 Famous MisquotationsWhat the sources actually say
Misquotations are not merely mistakes. They are cultural edits: context added, arguments compressed, and portable lines handed to more famous speakers.
A line survives by becoming easy to carry. “No, I am your father” needs a scene around it, so memory supplies Luke. A long argument by Gandhi becomes an imperative. An unattached aphorism drifts toward Einstein, whose name makes almost any thought look settled. The altered versions often travel better than the record.
That does not make every misquotation worthless, or every change fraudulent. A paraphrase can preserve an idea; a film misquote can restore missing context. But a useful adaptation is still different from a documented quotation. The notes below keep those differences visible and point to the strongest available record.
“In the middle of difficulty lies opportunity”
Usually credited to: Albert Einstein
What the record shows: The earliest solid trail leads to physicist John Archibald Wheeler. In a 1979 interview, Wheeler said Einstein's work revolved around three rules and gave this as the third. He was describing Einstein's method, not quoting a documented sentence by Einstein; later repetitions dropped that distinction.

Usually credited to: Mahatma Gandhi
What the record shows: No primary text has been found with this wording. Gandhi did write in 1913 that changing ourselves changes the tendencies of the world around us, but that longer argument is not the slogan. Research published by the Gandhi Peace Foundation traces the compact English wording to much later circulation.

Usually credited to: Voltaire
What the record shows: Evelyn Beatrice Hall wrote the sentence in her 1906 book The Friends of Voltaire. In context it summarizes Voltaire's attitude; it is not presented as a line from one of his works. Hall later explicitly said the wording was her own.

Usually credited to: Albert Einstein (also Benjamin Franklin and Mark Twain)
What the record shows: There is no substantive evidence that Einstein, Franklin, or Twain said it. Quote researcher Garson O'Toole finds related language in recovery communities in the early 1980s and the familiar sentence in Rita Mae Brown's 1983 novel Sudden Death. It is an aphorism, not a clinical definition.

Usually credited to: Marie Antoinette
What the record shows: Rousseau's Confessions recalls an unnamed 'great princess' saying the peasants could eat brioche. He drafted that part of the book before Marie Antoinette moved to France, while she was still a child in Austria. Rousseau does not name her, and no evidence shows that she said it.

Usually credited to: Sherlock Holmes (Arthur Conan Doyle)
What the record shows: The exact sentence does not appear in Conan Doyle's sixty Holmes stories. Doyle used 'elementary' and 'my dear Watson' separately. An exact version was already in P. G. Wodehouse's 1915 novel Psmith, Journalist; later stage and screen Holmes performances made it the detective's catchphrase.

Usually credited to: The Bible
What the record shows: This is a compressed paraphrase of 1 Timothy 6:10, and the exact wording depends on the translation. The NRSVue reads, 'For the love of money is a root of all kinds of evil'; the King James Version has 'the root of all evil.' Either way, the subject is the love of money, not money itself.

Usually credited to: Winston Churchill
What the record shows: In the House of Commons on 13 May 1940, Churchill said he had 'nothing to offer but blood, toil, tears and sweat.' The shorter three-part form is not the wording of that speech, although similar combinations of blood, sweat, and tears predate it.

Usually credited to: Darth Vader, The Empire Strikes Back
What the record shows: Darth Vader's line is 'No, I am your father.' Adding Luke's name makes the quotation recognizable when it is removed from the exchange that precedes it, which helps explain why the altered version travels so well.

Usually credited to: Casablanca
What the record shows: Nobody in Casablanca says those four words. Ilsa asks, 'Play it, Sam. Play As Time Goes By,' and Rick later tells Sam to 'Play it.' The already familiar misquotation became the title of Woody Allen's 1969 play and its 1972 film adaptation.

Usually credited to: Apollo 13
What the record shows: The mission recording uses the present perfect: Jack Swigert reported, 'Houston, we've had a problem here,' and Jim Lovell repeated that they had had a problem. The 1995 film changed the line to the present tense.

Usually credited to: Marilyn Monroe
What the record shows: Historian Laurel Thatcher Ulrich wrote 'Well-behaved women seldom make history' in a 1976 article about women in Puritan funeral sermons. The sentence concerned the historical record's neglect of conventional women's lives; 'rarely' is a later variant, and Monroe was not its author.
Source: Harvard Gazette on Ulrich's original context“The ends justify the means”
Usually credited to: Niccolò Machiavelli
What the record shows: That sentence does not appear in The Prince. Chapter XVIII does argue that a ruler is often judged by the result and may need to act against ordinary virtues. The maxim is therefore a blunt summary of part of Machiavelli's argument, not a quotation from him.
Source: Niccolò Machiavelli, The Prince“Jack of all trades, master of none — but oftentimes better than a master of one”
Usually credited to: 'the full original quote'
What the record shows: The historical layers arrived at different times. 'Jack of all trades' is in print by 1618, while critical continuations such as 'master of none' appear later. The approving 'oftentimes better' clause is a modern extension, not a recovered original.
Source: Oxford Text Archive: Geffray Minshull (1618)“Curiosity killed the cat”
Usually credited to: proverb, often with 'but satisfaction brought it back'
What the record shows: The older proverb was 'care killed the cat,' with care meaning worry; Ben Jonson used it in 1598. Versions with curiosity appear in the nineteenth century. 'Satisfaction brought it back' is documented in the early twentieth century, so it is an addition rather than a missing half of the older saying.
Source: The Phrase Finder's dated citations“The customer is always right — in matters of taste”
Usually credited to: Harry Gordon Selfridge, 'the forgotten full quote'
What the record shows: Early twentieth-century sources record the short retail slogan and variants such as 'the customer is never wrong.' They do not supply 'in matters of taste' as a lost ending. That qualification is a modern reinterpretation, and the slogan's exact origin is shared among several retailers rather than securely owned by Selfridge.

A famous quotation has two histories: the thought it carries and the route by which its wording acquired a speaker. The real origin does not spoil the line. It reveals the editing that made the line famous, while preserving the difference between a quotation, a paraphrase, and folklore.
