If You Steal From One Author, It’s Plagiarism; If You Steal From Many, It’s Research

Wilson Mizner? Ralph Foss? Steven Wright? Joseph Cummings Chase? Asa George Baker? Leslie Henson? Tom Lehrer? Bob Oliver? Anonymous?

Dear Quote Investigator: Some of the websites I come across seem to produce their content simply by using cut and paste. They do not even bother to collect information from multiple sources. I am reminded of a very funny one-liner:

To steal ideas from one person is plagiarism; to steal from many is research.

In recent times these words have been credited to the brilliantly out-of-kilter comedian Steven Wright, but I have also seen the quip attributed to the playwright and confidence man Wilson Mizner. Could you investigate this saying?

Quote Investigator: An enjoyable precursor of the expression was printed in 1820. In the following humorous statement from Reverend Charles Caleb Colton the era of the material being appropriated was considered decisive. Thanks to a commenter named Jutta for pointing out this citation: 1

If we steal thoughts from the moderns, it will be cried down as plagiarism; if from the ancients, it will cried up as erudition.

The earliest match located by QI appeared in 1932 in a journal called “Special Libraries” which reported on a talk given at an annual conference for librarians. Ralph Foss, the director of sales at the McGraw-Hill publishing company, presented a version of the saying and ascribed it to an anonymous individual: 2

I am reminded of the man who was asked what plagiarism was. He said: “It is plagiarism when you take something out of a book and use it as your own. If you take it out of several books then it is research.”

In 1938 a version of the saying was credited to Wilson Mizner in a book titled “Tales of a Wayward Inn” by Frank Case. The famed Algonquin Round Table met in a hotel that was owned and managed by Case, and his memoir described his experiences as a host. Note that Mizner died in 1933 several years before the book was published: 3

As Wilson Mizner says, “When you take stuff from one writer it’s plagiarism, but when you take from many writers it’s called research.”

In the same year, 1938, Joseph Cummings Chase, a prominent portraitist and art teacher, wrote a piece in “The Commentator” magazine that included a variant of the quotation. Chase was head of the Art department at Hunter College in the 1930s: 4

When a research professor takes pen in hand to do a book on Art he writes on and on without any evidences of the ability to stop. By and by out come five or six hundred more pages largely culled from the tomes of the research lads before him. On the title page of most of the books on Art should be printed, “If you steal from one person it’s plagiarism: if you steal from three persons it’s research.”

Here are additional selected citations in chronological order.

The saying was further spread in 1938 via newspapers such as the Santa Fe New Mexican. 5 A short filler item replicated the adage and credited it to “The Commentator” without mentioning Chase’s name. The Santa Fe paper was dated September 29, 1938 while “The Commentator” issue was dated October. This dating sequence occurred because “The Commentator” was available to readers before its cover date:

(The Commentator Magazine)

On the title page of most of the books on art should be printed: “If you steal from one person it’s plagiarism; if you steal from three persons it’s research.”

A book titled “Professional Writing” published in 1938 by a teacher at the University of Oklahoma presented advice to future authors. The teacher presented an entertaining variant expression that matched the theme of the quotation: 6

He apparently followed the advice of Vida, who told beginners to steal from every source. It is the same in literature as in certain other walks of life: as the saying goes—the man who robs one bank is a common thief; the man who robs a hundred is a financier. The moral is, in literature, not to steal from one author, but to learn from many, Plagiarism is not only a crime, but a mark of stupidity, like robbing a country bank.

In December 1938 an instance of the quotation appeared in Word Study, a periodical from G. & C. Merriam Company which was best known for publishing the Merriam-Webster dictionaries. The saying was ascribed to an unnamed or archetypal librarian: 7

Asa G. Baker quotes a librarian’s distinction between plagiarism and research: “If you wrote a paper and quoted without credit from a single book, it would be plagiarism; but if you quoted from three or four, it would be research.”

Asa George Baker was the chairman of the board of directors and former president of the G. & C. Merriam Company. However, the editor of Word Study revisited this topic in 1939 and changed the attribution from a librarian to Mizner: 8

According to Frank Case’s Tales of a Wayward Inn, the saying quoted in a recent issue of WORD STUDY originated with Wilson Mizner, and ran as follows: “When you take stuff from one writer, it’s plagiarism, but when you take it from many writers, it’s called research.”

In 1939 a book about marketing products in Canada was published. One chapter was written by Henry King, a market researcher, and he claimed that the saying was used by a popular English music hall comedian named Leslie Henson: 9

“If you get information from one source,” said Leslie Henson in his recent London show, “it’s called plagiarism; if you get it from two or more sources, it’s called research.”

In 1941 a Hollywood gossip columnist writing in the Los Angeles Times attributed the jest to a person named Bob Oliver: 10

Bob Oliver suggests a simple rule-of-thumb for would-be movie scenarists.
“Just remember,” says he, “if you steal from one man, it’s plagiarism.  If you steal from several, it’s research.”

In 1942 The New Yorker magazine published an extensive multi-part profile of Wilson Mizner which contained several witty sayings ascribed to Mizner including the following: 11

If you steal from one author, it’s plagiarism; if you steal from many, it’s research.

Tom Lehrer, the recording artist and satirist, released a song in the 1950s titled Lobachevsky that contained the following lyrics: 12

Remember why the good Lord made your eyes,
So don’t shade your eyes,
But plagiarize, plagiarize, plagiarize –
Only be sure always to call it please ‘research’.

In 1974 a book review in the Los Angeles Times discussed Tom Lehrer’s song: 13

. . . reminds me of Tom Lehrer’s song about the Great Lobachevsky. One axiom of the mythical mathematician’s scholarly work was that if you steal from one source you are committing plagiarism; if you steal from two sources, you are providing documentation; and if you steal from three or more sources, it is – presto – “original research.”

The Lobachevsky referred to in the song is not mythical. Nicolai Ivanovich Lobachevsky was a renowned Russian mathematician, but Lehrer was not being critical. The Wikipedia entry for Lobachevsky cites the liner notes of a 2010 album by Lehrer and states: 14

According to Lehrer, the song is “not intended as a slur on [Lobachevsky’s] character” and the name was chosen “solely for prosodic reasons”.

The joke was attributed to comedian Steven Wright at the MustShareJokes website. 15The saying was also credited to Wright in a 2008 book in the field of Academic Medicine. 16

To steal ideas from one person is plagiarism — to steal from many is research.

In conclusion, the earliest evidence found by QI was dated 1932. The joke was told by Ralph Foss of McGraw-Hill publishing, but his phrasing left the ascription anonymous. In 1938 the quip was attributed to Wilson Mizner who died in 1933. If Mizner did tell the joke then it was in the same time period as the earliest known citation or earlier. Joseph Cummings Chase also used a version of the saying in a magazine essay in 1938. Perhaps more evidence will be located in the future.
