Paul's father Lajos was captured by the Russian army as it attacked the Austro-Hungarian troops. He spent six years in captivity in Siberia. As soon as Lajos was captured, with Paul's mother Anna teaching during the day, a German governess was employed to look after Paul. Anna, excessively protective after the loss of her two daughters, kept Paul away from school for much of his early years and a tutor was provided to teach him at home. The year 1920 was not all bad for Paul, for his father Lajos returned home from Siberia. He had learnt English to pass the long hours in captivity but, having no English teacher, did not know how to pronounce the words. He now set about teaching Paul to speak English, but the strange English accent which this gave Paul remained one of his characteristics throughout his life.

A child prodigy, he was mostly home-schooled by his parents—both teachers of mathematics—until he entered the Univ. of Budapest in 1930. He graduated in 1934, simultaneously receiving his doctorate. After teaching in Europe, he joined the Institute for Advanced Study at Princeton Univ., where he stayed for ten years. The remainder of his life was filled with positions at a number of schools, among them the Univ. of Pennsylvania, Notre Dame, Purdue, and Stanford, and making conference presentations. Although he was interested in history, medicine, and politics, his life was dedicated to mathematics. Erd¶s wrote about 1,500 papers, about five times as many as other prolific mathematicians, and had about 500 collaborators. He wrote fundamental papers on real analysis, geometry, topology, probability theory, complex analysis, approximation theory, and set theory, but he will be remembered best for his contributions to number theory and combinatorics , an area of mathematics fundamental to computer science.

"Let him be blessed who takes my place!" He was a great mathematician in the usual sense, i.e., he proved an army of theorems. He mostly worked in number theory and in combinatorics, in fact he can be called the most prominent figure of the latter subject. But he also worked in set theory, analysis, approximation theory, probability theory. Perhaps he is best known for his elementary proof, with Atle Selberg, of the prime number theorem. He had a special ability to ask the right questions, and he enjoyed imposing conjectures, specially in new topics. Frequently, his conjectures made into central theorems, some generated deep results, and some are still unsolved, indeed they seem to be very hard.

Paul Erdös : review of Paul Hoffmann's The man who loved only numbers. To home page. Paul Erdös was the second most prolific mathematician in history, after the Swiss, Leonhard Euler. He is the most prolific collaborator with other mathematicians. Hence, an ordinal number system named after him, which grades how closely any mathematician came to work with him. If you have an 'Erdös number one', that means you actually did a mathematical paper with this prodigy. 'Erdös number two' means you have done a joint paper with a mathematician who did a paper with Erdös. I know someone whose bigger brother is an Erdös number two. She wonders if having her homework done for her, by said brother, makes her an Erdös number three. Sadly not. At our book club, we gave little talks about a book we had read. She enjoyed my talk about Paul Hoffmann's title, some time ago. She said I was right: he did bring his mother along with him. Indeed, that much I had faithfully gleaned from Hoffmann. ( Unfortunately, I can't remember exactly what I said. The following account differs somewhat. ) Paul Erdös was of Jewish Hungarian extraction. The book says the name Erdös is pronounced 'air-dish'. But I'm told the Hungarian pronunciation is actually 'err-desh'. That is err, as in 'to err is human, to forgive is divine', and desh, as in Bangladesh. ( Scots would give 'err' its traditional and phonetic pronunciation, which does sound like the normal pronouncing of 'air', but I mean the more typical pronunciation of 'err', as the unstressed vowel sound. )

A mathematician has an Erdös number of 1 if he or she has published a paper with Erdös, of 2 if he or she has published with someone who published a paper with Erdös, and so on. Erdös worked almost non-stop, 19 hours a day, 7 days a week. "A mathematician," he quipped, "is a machine for turning coffee into theorems." At age 20, Erdös discovered an elegant proof of a famous theorem in number theory , known as Chebyshev's theorem , which says that for each number greater than one, there is always at least one prime number between it and its double. Number theory remained one of his chief interests, though his work spread across many fields, and he became renowned for posing and solving problems that were often simple to state but notoriously difficult to solve. He did groundbreaking work in a branch of mathematics known as Ramsey theory long before it became fashionable in the late 1950s. BACK TO TOP var site="s13space1234"

Considered by many as one of the great mathematicians of this century and certainly one of the most prolific ever, he will be missed. For more than 50 years, Erdos wandered the globe visiting mathematicians, attending meetings, teaching, and lecturing. He had become the center of an enormous web of collaboration (see Groups, Graphs, and Paul Erdos "One never knew where Erdos was, not even the country," Richard Bellman wrote in Eye of the Hurricane . "However, one could be sure that during the year ... Erdos was everywhere. He was the nearest thing to an ergodic particle that a human being could be." At his death, Erdos had more than 1,500 published papers to his credit. He was active to the last days of his life. At least 50 papers on which he is listed as a coauthor are yet to appear, representing the results of various recent collaborative efforts. Erdos was the supreme problem poser and problem solver of modern times. His interests were mainly in number theory and combinatorics, though they ranged into topology and other areas of mathematics. He was fascinated by relationships among numbers, and numbers served as the raw materials for many of his conjectures, questions, and proofs.
