Mathematician:Paul Erdős

In Hungarian: Erdős Pál. Hungarian mathematician known for the vast quantity of work he did (approximately 1500 papers).

Spent his entire life travelling the world looking for interesting mathematical problems to solve.

Perhaps most famous for his widespread collaborations (about 500 collaborators), from which the concept of the Erdős Number emerged.

Found an elementary proof in 1949 of the Prime Number Theorem at the same time as Atle Selberg. They were to have published simultaneously in separate journals, each giving credit to each other, but Selberg rushed ahead and published first, thereby gaining not only all the credit, but also the Fields Medal. Erdős was, reportedly, "philosophical".

Because of his widespread influence, there are many stories in circulation about Erdős, not all of which are completely true, so don't believe everything you read about him (even this!) - its source may be flawed.
