Many mathematicians know that Lewis Carroll was quite a good mathematician, who wrote about logic (paradoxes) and determinants. He found an expansion formula, which bears his real name (Charles Lutwidge) Dodgson. Needless to say, L. Carroll was his pseudonym, used in literature.

Another (alive) mathematician writes under his real name and under a pseudonym (John B. Goode). (That person, by the way, is Bruno Poizat: it's no secret, even MathSciNet knows it.)

What other mathematicians (say dead ones) had a pseudonym, either within their mathematical activity, or in a parallel career ?

Of course, don't count people who changed name at some moment of their life because of marriage, persecution, conversion, and so on.

Edit. The answers and comments suggest that there are at least four categories of pseudonyms, which don't exhaust all situations.

  • Professional mathematicians, who did something outside of mathematics under a pseudonym (F. Hausdorff - Paul Mongré, E. Temple Bell - John Taine),
  • People doing mathematics under a pseudonym, and something else under their real name (Sophie Germain - M. Le Blanc, W. S. Gosset - Student)),
  • Professional mathematicians writing mathematics under both their real name and a pseudonym (B. Poizat - John B. Goode),
  • Collaborative pseudonyms (Bourbaki, Blanche Descartes)

I guess, though I am not sure, the case of Albert Wormstein falls in your third category:

Professional mathematicians writing mathematics under both their real name and a pseudonym.

This paper: "Polyominoes of order 3 do not exist" (Journal of Combinatorial Theory, Series A, Volume 61, Issue 1, September 1992, Pages 130–136) has been written by I. N. Stewart and A. Wormstein.

Here is the story behind the paper as told by Ian Stewart himself.

The link has the correct story. Albert Wormstein first appeared in one of my articles for Pour La Science / Scientific American, which was used as a chapter in the cited book. While I was writing that article it suddenly seemed clear that there ought to be a way to prove the conjecture about order 3 polyominoes. It felt as though Albert was tapping me on the shoulder and saying 'come on, we can do this.' It quickly turned out he was right. So I decided to give him credit as a co-author. The journal either spotted the joke and went along with it, or they assumed Albert was a PhD student. At any rate, they published it with him as co-author.

Elena Ventzel is not a very famous mathematician, although her textbook on Probability for engineers was (still is?) by far the most famous and widely used one in Russia.

She had a successful separate career as a fiction writer under a pen-name I. Grekova (derived from "igrek").

Boto von Querenburg wrote a book on general topology, which is one of the standard source in German. According to Wikipedia the name actually stands for the authors Gunter Bengel, Hans-Dieter Coldewey, Klaus Funcke, Edelgard Gramberg, Norbert Peczynski, Andreas Stieglitz, Elmar Vogt and Heiner Zieschang. The name Boto was chosen as an abbreviation of "Bochum topologists" and the University of Bochum is in a part of the town called Querenburg.

Rainich=Rabinowitsch (of trick fame : cf. Nullstellensatz).

Here is an anecdote related by Bruce P. Palka, Editor of American Mathematical Monthly in Vol.111 (2004) of that journal (page460).

Rainich was giving a lecture in which he made use of a clever trick which he had discovered. Someone in the audience indignantly interrupted him pointing out that this was the famous Rabinowitsch trick and berating Rainich for claiming to have discovered it. Without a word Rainich turned to the blackboard, picked up the chalk, and wrote


He then put down the chalk, picked up an eraser and began erasing letters. When he was done what remained was

                   RA IN  I CH

He then went on with his lecture.

EDIT: There is some additional information (located by Sándor Kovács) to be found at We reproduce the relevant section below:

"Lance also contributes some new information to the saga of the elusive Mr. Rabinowitsch (see the Editor's Endnotes in the May 2004 issue): Poor Rabinowitsch, whoever he may be. The correct reference is: J. L. Rabinowitsch, "Zum Hilbertschen Nullstellensatz", Math. Ann. 102 (1930), p.520. In various places his first initial is either "A" or "S." On my trip to the library, I saw that Rainich had published in the Annalen under his own name and from Ann Arbor the previous year. Why a pseudonym?" The mystery deepens a bit in a biography of Rainich, where it's mentioned that he was born Rabinowitsch. On the same theme, Herman Roelants of Leuven, Belgium, points out that a Rabinowitsch anecdote similar to the one in the May 2004 MONTHLY is found on page 959 of the MONTHLY paper "Reminiscences of an Octagenarian Mathematican" by L. J. Mordell (November, 1971). Herman goes on to say that details concerning this source, together with references to important number-theoretic work of Rabinowitsch, can be found in the text and in a footnote on page 108 of Richard A. Mollin's book Quadratics (CRC Press, 1996).”

E. S. Pondiczery was a pseudonym used by R. P. Boas, Jr. in the paper Power problems in abstract spaces. The name became part of the well-known Hewitt-Marczewski-Pondiczery theorem.

Another pseudonym used by Boas (and F. Smithies) was H. Pétard. I highly recommend that you take a look at the hilarious Lion hunting and other mathematical pursuits (A collection of mathematics, verse, and stories by the late Ralph P. Boas, Jr.) for more information in this regard.

Added (Nov 7/2010). In that book you can also learn about other pseudonyms (for instance, Ian Stewart's one) and the memorable feud 'twixt Bourbaki and Boas.

Added (Nov 8/2010). According to page 10 of the aforementioned book, H. Pétard was in fact a pseudonym that Boas and Smithies made up for the use of E. S. Pondiczery.

Although some think of Pythagoras as one person, it is now thought that his name is used for geometric and number theoretical discoveries made by anonymous members of his sect.

Thus, we can think of "Pythagoras" as the pseudonym of a collective of Greek intellectuals from about 500 BCE.

Joseph Bernstein published a paper under the pseudonym "Yantarov" (which is derived from the Russian translation of the German word "Bernstein" which means "amber"). At the time of writing he was an "otkaznik", a person waiting for permission to emigrate from the USSR, and a paper under his own name would not be accepted.

Henri-Paul de Saint Gervais is a collective pseudonym of fifteen mathematicians who recently published a book, Uniformisation des surfaces de Riemann, retour sur un théorème centenaire, about the uniformization of Riemann surfaces. (presentation of the book, in French). They met in Saint-Gervais to work on the book, hence the lastname. The firstname, Henri-Paul, reminds of Henri Poincaré and Paul Koebe, of course! By the way, this book is highly recommended !

I'm surprised that no one named Leonardo of Pisa, known as Fibonacci to us (though he didn't use this nickname, and its origin is not completely clear).

Al-Khoresmi is apparently a nickname as well (though this time used by the author), meaning his origin.

(Maybe not exactly an answer to the original question, because these are rather nicknames, not pseudonyms.)

share|cite|improve this answer
I think that Leonardo da Pisa is the nickname (whose meaning is clear), while Fibonacci is his family name, being the contraction of "filius bonacci"="son of Bonacci". – Gian Maria Dall'Ara Nov 8 '10 at 16:05
If you mean by Al-Khoresmi "Abu Ja'far Muhammad ibn Musa Al-Khwarizmi" then I think he does not qualify. It was customary at the time to use geographic names of family origin as family name. This means that he had the name "Al-Khwarizmi" all his life and that his father, brothers and sons (if he had any) had the same name. – Hany Nov 8 '10 at 19:56
Few sidenotes: 1. Bearing the name Abu Jafar implies that he most probably had a son named Jafar. 2. drawing a line between first and family name in Oriental naming schemes is quite hard - so one can consider 'al-Khwarizmi' as just a part of his family name. 3. My experience tells me that most of people with 'geographic' family names get those when they move - i.e. I believe Al-Khwarizmi is not an exception in that case - family probably got the name when they moved to the south. This is a bit off-topic, but I couldn't help it. – Harun Šiljak Nov 8 '10 at 20:39
It was common in the early middle ages to identify people by their first name and home town, hence names like Leonardo of Pisa. In his time, the transition to using family names as we do today was under way. Fibonacci means "of the Bonacci family," not "son of Bonacci." (His father's name with Guglielmo). He also used the name Bigollo, which was truly a nickname. – Michael Renardy Mar 31 '11 at 10:13

Hugo Steinhaus was also an author of aphorisms, which he published in the daily "Slowo Polskie" under a pseudonym Sestertius. Most were just goofy definitions of everyday terms. The following example seems to do OK in translation from Polish: "An opinion that all high-rank officers are stupid: a generalization". The book edition ("Slownik Racjonalny") appeared in 1980 (after his death) under his real name.
