1. Erdös was an interesting mathematician. He firmly believed in the beauty of mathematics, and was considered to be a founder of mathematical truth. His studies focused mostly on number theory, combinatorics, and graph theory.

2.  Erdös was born in Hungary to a Jewish family in 1913.  His parents where mathematics teachers. At a young age he was introduced complex mathematical ideas, that some of us may only be introduced to at a graduate level.  During his teens, he actively responded to posed problems from KöMaL.  He studied in Budapest, Hungary where he earned a doctorate in 1934 (he was only 21).  He was essentially forced out of Hungary and thus, his travels began.  In 1949, he and Selberg discovered an elementary proof for the Prime Number Theorem.  Erdös dies in 1996.  In 1998, The Man Who Loved Only Numbers is released as a biography of Erdös. It includes many personal stories and the many success of his lifetime.

3.  Property was considered to be nuisance to Erdös.  He essentially lived out of a suitcase as he traveled around the globe to study mathematics.  He spent time in the US, the UK, Canada, France, Hungary, Israel, Australia, the Netherlands, and many other countries.  Erdös frequently resided with Ronald Graham and his wife Fan Chung Graham. Graham was in a sense, some stability for Erdös.

4.  Erdös posed several problems throughout his lifetime. His problems included a prize in reward to a correct solution. The higher the prize money, the harder the problem.  Erdös was credited and or co credited to over 1,000 papers.

5.  An Erdös number is defined by how close you are to working on a paper with him.  Erdös, himself has an Erdös number of 0, while those who co-authored a paper with him had an Erdös number of 1.  If you co-author a paper with someone who has an Erdös number of 1, then you are a 2.  Wikipedia actually has a list (surely it is incomplete) of people with Erdös numbers ranging from 1 to 3, with over 500 people having a number 1.  http://en.wikipedia.org/wiki/List_of_people_by_ Erd%C5%91s_number http://en.wikipedia.org/wiki/List_of_people_by_ Erd%C5%91s_number
