Paul Erdös (1913-1996) was one of the most prolific mathematicians of all time. He authored or coauthored around 1500 articles and books. The Erdös number measures the distance of a given mathematician from Erdös on a graph whose edges denote the relationship of coauthorship. Click for the Erdös Number Project home page.
