Introduction

Paul Erdős (1913–1996) was a highly influential Hungarian mathematician who, particularly in the latter part of his life, dedicated much of his time to co-authoring papers with a vast number of colleagues—more than 500—on unsolved mathematical problems. He published more papers during his lifetime (at least 1,525) than any other mathematician in history. (By comparison, Leonhard Euler produced more total pages of mathematics, but fewer individual papers—around 800.) Erdős lived an unconventional lifestyle, often without a permanent home or job. He traveled with everything he owned in two suitcases, visiting collaborators—often unannounced—and staying with them while working together.
To say that someone is a co-author of Pál Erdős is equivalent to stating that his or her Erdős number is one. In general, the Erdős number represents the 'collaborative distance' between the mathematician Pál Erdős and another individual, measured by co-authorship of mathematical papers. Over time, it gained recognition as a means of analyzing how mathematicians collaborate to solve complex problems. Several research projects use the Erdős number as a tool to study connectivity among researchers. For instance, Erdős collaboration graphs can reveal how authors form clusters, how the number of co-authors per paper changes over time, and how new theories spread through academic networks.
Several studies have shown that leading mathematicians tend to have particularly low Erdős numbers. Among Fields Medalists, the median Erdős number is 3. More than 13,000 individuals have an Erdős number of 2 or lower. Over time, the lowest Erdős number that can still be attained will inevitably increase, as mathematicians with low Erdős numbers eventually pass away and are no longer available for collaboration. Nevertheless, some historical figures still have surprisingly low Erdős numbers. For example, according to the "Collaboration Distance" tool provided by MathSciNet, the renowned Indian mathematician Srinivasa Ramanujan has an Erdős number of 3—even though Paul Erdős was only seven years old when Ramanujan died.

Importantly, Erdős numbers are not limited to professional mathematicians. For instance, Mark Zuckerberg, founder of Facebook (now Meta), and the world-famous Hungarian inventor Ernő Rubik both have an Erdős number of 3. Bill Gates, the principal founder of Microsoft, has an Erdős number of 4. The American actress and mathematician Danica McKellar (born in 1975) also has an Erdős number of 4, thanks to a joint paper she coauthored with Princeton University professor Lincoln Chayes, who has an Erdős number of 3.

According to the aforementioned MathSciNet tool, an individual's Erdős number can be determined. However, the main limitation of this tool is that it only considers publications indexed in the MathSciNet database. As a result, the computed Erdős number may be inaccurate. For example, MathSciNet does not include joint publications between Paul Erdős and the following authors: Imre Csiszár, Ervin Feldheim, Joseph Gillis, Vojtěch Jarník, Donald Norton, Richárd Obláth, and Andrew Vázsonyi. Nevertheless, these collaborations—seven in total—are indexed in the Zentralblatt MATH database. Therefore, although the MathSciNet tool does not reflect it, each of these seven individuals does, in fact, have an Erdős number of 1.
There is some debate among mathematicians regarding the exact number of Erdős’s co-authors. While 512 is the generally accepted number, as established in [2], some argue that this count should exclude publications that appeared after Erdős’s death. However, determining which papers were actually written before his passing in 1996 is not straightforward, as the time between writing and publication can vary considerably. For practical purposes, one might consider as posthumous those papers that were published in 2002 or later. Based on this criterion, the number of Erdős’s direct co-authors (i.e., those with Erdős number 1) would be five fewer than 512. The individuals excluded under this interpretation would be Steve Butler, Persi Diaconis, Florian Luca, Michael Molloy, and Geert Prins. (Recently, two additional co-authors, Dave Galvin and Michael Krieger, were identified, bringing the total to 514, due to a paper published in 2022.) Additionally, according to some mathematics professors, in multi-authored papers involving Erdős and two or more collaborators, certain contributors may have played such a minor role that they should not be regarded as genuine co-authors of Erdős.

The biographical sketches in this booklet are not necessarily proportional to the professional activity or prominence of the individuals featured. There are several possible reasons for this. In some cases, limited information is available about a particular author. Conversely, when extensive information is readily accessible in English, I have often chosen to provide a hyperlink to an existing biography and include only a brief excerpt. When no English-language biography is available—or is difficult to find, even if one exists in another language—I have generally included a more detailed summary of the person’s life and work, based on information obtained through personal contact with the individual or one of their relatives.

Preliminaries and acknowledgement

Through an extensive multi-stage search and numerous personal inquiries, I was able to gather biographical data on the vast majority of Erdős’s collaborators. Out of 514 co-authors, I identified the year of birth for 418 individuals (including the full birth date for 375 of them), and the place of birth for 373 individuals.

The author would like to express his gratitude to Béla Bollobás, who helped a lot in collecting the data, first by having the data of some of Erdős' co-authors that were not available online, and by requesting and receiving data from others by letter. Unfortunately, our combined efforts were not enough to obtain the birth data of at least 420 of the 514 co-authors, although I had originally hoped for greater success.
Thanks are due also to Jerrold W. Grossman, the initiator and leader of the Erdős Number Project, for providing extensive additional information and for carefully reviewing this work.
I thank Gábor Nagy and Ferenc Mizera for their frequent help with technical matters. G. Nagy converted my files to PDF format, while F. Mizera uploaded the converted files to an online domain.

Brief summary of a small statistics
Using the collected data, a light statistical analysis was performed. The results – including Erdős himself, for a total of 515 individuals – are summarized below, 1. by place of birth (state or country/federation), 2. by year of birth, 3. by month of birth, 4. by the day of weak of birth.
For the sake of simplicity, column 1 lists the place of birth according to the current country in which the city is located at present (in 2025). Since Paul Erdős was Hungarian by birth and spoke Hungarian as his mother tongue, it is not surprising that, after the United States, the highest number of his co-authors were born in Hungary. It is also worth noting that several of Erdős’s other co-authors of Hungarian nationality were born in regions that belonged to Hungary before the 1920 Treaty of Trianon but are now part of Slovakia, Ukraine, Romania, Serbia, or Croatia. The statistics on years of birth shown in column 2 — grouped by half-decades — indicate that most of Erdős’s co-authors were born in the 1930s, 1940s, and 1950s. Column 3 reveals an interesting pattern: based on the distribution of birth dates by month, significantly fewer of Erdős’s co-authors were born in November, December, and January than average, while significantly more were born in March, May, and August. It may be even more interesting that significantly more of Erdős’s co-authors were born in Wednesday and Thirsday than other days of weak.

Biographies of Paul Erdős and his co-authors
First, we present a brief biography of Paul Erdős, written in the same style intended later for his co-authors. An asterisk before a name indicates that the following is a biography of a person who is known to be deceased.
*Paul Erdős (Budapest, Hungary, 26 March 1913 – Warsaw, Poland, 20 September 1996) was a Hungarian mathematician renowned for his prolific output and influential contributions across multiple fields of mathematics. He earned his Ph.D. from Eötvös Loránd University (Budapest) in 1934 under the supervision of Leopold (Lipót) Fejér. Erdős was one of the most productive mathematicians of the 20th century and a prolific originator of mathematical problems and conjectures. His research spanned a wide range of areas, including discrete mathematics, graph theory, number theory, mathematical analysis, approximation theory, set theory, and probability theory. Much of his work focused on solving concrete, previously unsolved problems, particularly in discrete mathematics. He made significant contributions to Ramsey theory, which investigates the conditions under which order must emerge in large structures. Rather than developing entirely new branches of mathematics, Erdős was primarily driven by the pursuit of elegant solutions to existing open problems.

Finding the exact or near-exact birth years of all of Erdős' co-authors would be a virtually impossible data-mining task. Through considerable effort and the assistance of artificial intelligence, the number of missing birth years was reduced to fewer than 100, albeit at the cost of a substantial amount of time. I want to emphasize that I only accepted information from artificial intelligence (specifically ChatGPT) if it came from sources that were verifiable—and that I personally verified.
Of Paul Erdős’s 514 co-authors, the date—or at least the year—of birth has been identified for a little more than 400 of them. The brief biographies below are arranged primarily in order of birth date. Accordingly, we begin with the biographies of the 400+ co-authors whose exact or approximate years of birth are known.
For the remaining co-authors, the only available common information is the year of their first joint publication with Pál Erdős. These individuals are listed separately at the end, in chronological order based on that publication year—which, presumably, correlates at least to some extent with their birth years.
Let us begin with Erdős’s oldest (and now deceased) co-authors.
*Richárd Obláth (Versec, Austria-Hungary, now Vršac, Serbia, 11 June 1882 – Budapest, Hungary, 18 June 1959) was a Hungarian mathematician. He worked as a secondary school teacher and held the title of Candidate of Mathematical Sciences. He received his Ph.D. (Candidate of Science degree) from the Hungarian Academy of Sciences in 1955. His joint publication with Erdős appeared in 1937.

*Norman Herbert Anning (28 August 1883 – Sunnydale, California, US, 1 May 1963) was a Canadian-American mathematician who served as an assistant professor, professor emeritus, and mathematics instructor. He is recognized for co-authoring a proof that characterizes infinite sets of points in the plane with pairwise integer distances—a result now known as the Erdős–Anning Theorem. His joint publication with Paul Erdős was published in 1945. The theorem states that an infinite set of points in the plane can have all pairwise distances as integers only if all the points lie on a straight line.

*Gábor Szegő (Kunhegyes, Hungary, 20 January 1895 – Palo Alto, California, US, 7 August, 1985) was a Hungarian-American mathematician and one of the foremost mathematical analysts of his generation. He made fundamental contributions to the theory of orthogonal polynomials and Toeplitz matrices, building on the work of his contemporary Otto Toeplitz. He received his Ph.D. from the University of Vienna in 1918 under the supervision of Wilhelm Wirtinger and Philipp Furtwängler. He co-authored two papers with Erdős, published in 1942 and 1961. He is also one of the namesakes of the Pólya–Szegő inequality, which states that the Sobolev energy of a function in a Sobolev space does not increase under symmetric decreasing rearrangement.

*Vojtěch Jarník (Prague, Austria-Hungary, now Czech Republic, 22 December 1897 – Prague, Czechoslovakia, now Czech Republic, 22 September 1970) was a Czech mathematician. He earned his Ph.D. from Charles University in Prague in 1921, under the supervision of Edmund Landau. Jarník spent much of his career as a professor and administrator at Charles University and played a key role in establishing the Czechoslovak Academy of Sciences. He is the namesake of Jarník's algorithm for constructing minimum spanning trees. This algorithm starts from a single vertex and repeatedly adds the cheapest available edge connecting the growing tree to a new vertex, until all vertices are connected. His joint publication with Erdős was published in 1937.

*Arthur Herbert Copeland (Rochester, New York, US, 22 June 1898 – 6 July 1970) was an American mathematician known for his work on the foundations of probability. He earned his Ph.D. from Harvard University in 1926, where his advisor was Oliver Dimon Kellogg. He later taught at Rice University and the University of Michigan. Copeland co-authored a paper with Erdős in 1946. Together, they introduced the Copeland–Erdős constant, formed by concatenating the base-10 representations of the prime numbers after "0.", yielding 0.235711131719... They proved this number to be both irrational and normal. Their results were published in the paper "Note on Normal Numbers" in the Bulletin of the American Mathematical Society.

*Pál Turán (Budapest, Hungary, 18 August 1910 – Budapest, Hungary, 26 September 1976) also known as Paul Turán, was a renowned Hungarian mathematician. He received his Ph.D. from Eötvös Loránd University (Budapest) in 1935, under the supervision of Lipót Fejér. He collaborated extensively with Erdős, resulting in 30 joint publications between 1934 and 1977. Turán is known for numerous fundamental results and concepts in mathematics, many of which bear his name, including Turán graph, Turán number, Turán's brick factory problem, Turán sieve, Turán's inequalities, Turán's lemma, Turán's theorem, Turán–Kubilius inequality, Erdős–Turán conjecture, Erdős–Turán inequality, Erdős–Turán–Koksma inequality, Kővári–Sós–Turán theorem. Turán's theorem is a foundational result in extremal graph theory. It states that a graph with n vertices that does not contain a complete subgraph of r + 1 vertices has at most as many edges as the corresponding Turán graph—constructed by partitioning the vertex set into r subsets of nearly equal size and connecting every pair of vertices from different subsets.

*Shizuo Kakutani (Japanese: 角谷静夫; Osaka, Japan, 28 August 1911 – New Haven, Connecticut, US, 17 August 2004) was a Japanese-American mathematician best known for the Kakutani fixed-point theorem, a generalization of Brouwer’s fixed-point theorem that applies to correspondences rather than functions. He received his Ph.D. from Osaka University in 1941, where his advisor was Tatsujiro Shimizu. Kakutani co-authored seven papers with Erdős, published between 1943 and 1961. He is also one of the namesakes of the Markov–Kakutani fixed-point theorem, which states that a commuting family of continuous affine self-maps on a compact convex subset of a locally convex topological vector space has a common fixed point. This result is instrumental in one of the most elegant proofs of the amenability of abelian groups. Kakutani also made significant contributions to stochastic processes, including his "Kakutani skyscraper" construction and a probabilistic solution to the Poisson equation.

*John Lewis Selfridge (Ketchikan, Alaska, US, 17 February 1927 – DeKalb, Illinois, US, 31 October 2010), was an American mathematician who made significant contributions to analytic number theory, computational number theory, and combinatorics. He received his Ph.D. from the University of California, Los Angeles in 1958, with Theodore Samuel Motzkin as his advisor. He co-authored 14 papers with Erdős, published between 1967 and 1999. Selfridge, along with John Conway, lends his name to the Selfridge–Conway procedure, a discrete method for achieving envy-free cake-cutting among three parties. Although Selfridge discovered the procedure in 1960 and shared it with Richard Guy, it was never formally published. Conway later discovered it independently, and it gained popularity in the 1990s through the work of Steven Brams and Alan Taylor.

Hickerson made pioneering contributions to cellular automata, particularly through the discovery of oscillators and spaceships in Conway’s Game of Life. In 1989, he created the first oscillator search program, which enabled the discovery of many small, low-period oscillators such as the caterer, monogram, and fumarole. He also found numerous sparkers and billiard table configurations, including the first known period-17 oscillators. His automated searches led to the discovery of new types of spaceships traveling at speeds of c/3, c/4, and 2c/5, including the first diagonal c/4 spaceship (other than the glider) and the first period-2 spaceships. In 1991, he achieved a major breakthrough by combining thirteen switch engines to form the first c/12 diagonal spaceship, known as the 13-engine Cordership. That same year, he designed the first sawtooth pattern, sawtooth 1212, using his c/3 spaceship called the turtle. His discoveries have had a lasting influence on cellular automata research.
