Open Questions from the MacTutor History of Mathematics archive , article by J J O'Connor and E F Robertson: Born: 26 March 1913 in Budapest, Hungary Died: 20 Sept 1996 in Warsaw, Poland Paul Erdös came from a Jewish family (the original family name being Engländer) although neither of his parents observed the Jewish religion. Paul's father Lajos and his mother Anna had two daughters, aged three and five, who died of scarlet fever just days before Paul was born. This naturally had the effect making Lajos and Anna extremely protective of Paul. He would be introduced to mathematics by his parents, themselves both teachers of mathematics. Paul was not much over a year old when World War I broke out. 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 situation in Hungary was chaotic at the end of World War I. After a short while as a democratic republic, a communist Béla Kun took over, and Hungary became a left wing Soviet Republic. Anna was at this time made head teacher of her school but when the Communists called for strike action against Kun's regime she continued working, not for political reasons but simply because she did not wish to see children's education suffer.

Paul Erd¶s b. Budapest, 26-Mar-1913 d. Warsaw, 20-Sep-1996 On September 20, 1996, at the age of 83, Paul Erd¶s, one of the foremost and one of the more interesting mathematicians of this century, died. Paul Erd¶s was associated with the mathematics department at the Technion since 1955 when he was appointed a “Permanent Visiting Professor”. This position permitted him to come to the Technion whenever he wanted, for as long as he wished, and to be paid a regular salary during these visits. He came frequently and these visits were of great value to the department, and hopefully also to him. There was, to my knowledge, never any talk of retirement or benefits. This was convenient both for him and for us. Paul often came every year for a month of so, however during the last 10 years he probably only came 6 or 7 times. He held this position until his death, and I understand that Paul even wrote a day or two before his death that he planned to visit here again in March, 1997. When this position was “arranged”, Paul was asked to write a CV of sorts. He wrote, by hand (and with his grammatical oddities), the following: [The uncertainty alluded to in the above lines had to do with his re-entry visa to the United States being denied (this was during the McCarthy era). The story is that Paul was asked by the immigration officials what he thought of Karl Marx, and he answered: “I'm not competent to judge, but no doubt he was a great man.”]

New York Times, September 24, 1996 Paul Erdos, a Math Wayfarer At Field's Pinnacle, Dies at 83 By GINA KOLATA Dr. Paul Erdos, a legendary mathematician who was so devoted to his subject that he lived as a mathematical pilgrim with no home and no job, died Friday in Warsaw, Poland. He was 83. The cause of death was a heart attack, according to an E-mail message sent out this weekend by Dr. Miki Simonovits, a mathematician at the Hungarian Academy of Sciences, who was a close friend. Erdos (pronounced AIR-dosh) was attending a mathematics meeting in Warsaw when he died, Simonovits reported. Never, mathematicians say, has there been an individual like Paul Erdos. He was one of the century's greatest mathematicians, who posed and solved thorny problems in number theory and other areas and founded the field of discrete mathematics, which is the foundation of computer science. He was also one of the most prolific mathematicians in history, with more than 1,500 papers to his name. And, his friends say, he was also one of the most unusual. Erdos, "is on the short list for our century," said Dr. Joel H. Spencer, a mathematician at New York University's Courant Institute of Mathematical Sciences.

68. Paulos Reviews Paul Erdos, John Nash Books I was awake enough to realize that it was paul erdos, one of the most curious (in both senses), prolific and insightful mathematicians of this century. http://www.math.temple.edu/~paulos/erdnash.html

I remember once while in graduate school at the University of Wisconsin staying at my office until 4 a.m. Stumbling through the hall bleary-eyed on my way home, I came upon a little gnome of a man who, as if it were the middle of the day, began questioning me about my results in a kindly yet most energetic way. Who should be haunting those empty halls at that hour, except janitors? I was awake enough to realize that it was Paul Erdos, one of the most curious (in both senses), prolific and insightful mathematicians of this century. It's not surprising that Erdos would often remark that a mathematician was a machine for turning coffee into theorems. Toward the end of his life he even partook of amphetamines to keep his mental machinery churning into the wee hours. Such eccentricity in the men who study circles and numbers is only part of the story of mathematicians Erdos and John Nash, the subjects of the new biographies "My Brain Is Open," "The Man Who Loved Only Numbers" and "A Beautiful Mind." But for many, the eccentricity may be the most intriguing part. Science writer Bruce Schechter's "My Brain Is Open" is a mathematical biography of Erdos, born in 1913 in Hungary to academic parents. Erdos was cosseted by a mother who had just lost her other two children to scarlet fever and educated by a father who early on taught him about prime numbers and infinite sets. Both influences were life-defining. In later years he related how he independently discovered the notion of negative numbers at the age of 3 but didn't butter his own toast until he was 20.

As far as I know, he had a heart attack, rather serious, very early in the morning, in this Warsaw hotel, where he stayed while visiting the Minisemester for Combinatorics, (for two weeks), gave two lectures. Vera Sos and Andras Sarkozy are leaving Budapest for Warsaw right now, Saturday morning, and Paul's original plans were to fly from Warsaw to Vilnius (for the Kubilius Conference) with Vera and Andras together, on Sunday. The doctor informed us that he had two heart attacks and the second one killed him. (Perhaps even the first one was serious enough to prevent him from communicating to his surrounding. This may explain e.g. that he could not reach the mathematicians. We learned about his heart attacks only after his death.) It came as a shock to me because when I last saw him at the Hungarian Academy of Science in Budapest on September 4, he was going over a paper with a young Hungarian mathematician and seemed to be working vigorously at what he loved to do. web site.

Paul Erdös LIFE ON BENZEDRINE Jewish Hungarian mathematician Paul Erdös Paul Erdös (1913-1996), "the man who loved only numbers", was one of the most brilliant and prolific mathematicians of the twentieth century. Erdös spent much of his restless life on psychostimulants. As he once remarked, "A mathematician is a device for turning coffee into theorems." But Erdös liked stronger medicine too. After his mother's death in 1971, Erdös became quite depressed. His physician prescribed amphetamines. Erdös took Benzedrine or Ritalin almost every day for the last twenty five years of his life. Sometimes he took both. Long-term use of amphetamines often exacerbates depression. When used chronically, too, amphetamines usually induce stereotyped thought and behaviour rather than creativity. But Paul Erdös seems to be an exception. He felt living on speed helped him to create maths. At an age when most mathematicians have long since burnt out, his output was certainly prodigious. Strong dopaminergic drugs also tend to provoke or exacerbate obsessive-compulsive behaviour. Here their effect on Erdös may be more typical. Erdös hated to be touched; and he washed his hands some 50 times a day.

80. David Hilbert And Paul Erdös Awards The paul Erdös National Award was established to recognise contributions of paul Erdös, born in 1913 in Hungary, was an indefatigable traveller, http://www.amt.canberra.edu.au/wfnmcaw.html

David Hilbert and Paul Erdös Awards The World Federation of National Mathematics Competitions has created two international awards for mathematicians who have contributed to mathematics enrichment in their own countries or internationally. They are named after two mathematicians who have been among the most prominent in providing mathematical challenge in the twentieth century. David Hilbert International Award The David Hilbert International Award was established to recognise contributions of mathematicians which have played a significant role in the development of mathematical challenges at the international level and which have been a stimulus for the enrichment of mathematics learning. Each recipient of the award is selected by the Executive and Advisory Committee of the World Federation of National Mathematics Competitions on the recommendation of the WFNMC Awards Subcommittee. David Hilbert (1862-1943) David Hilbert was one of the most outstanding mathematicians of the modern era. At the International Congress of Mathematicians in Paris in 1900 he presented the now famous and inspirational 23 problems which he challenged twentieth century mathematicians to solve.
