Paul Erdos,83, one of the century's most eminent mathematicians, died of a heart attack Friday in Warsaw, Poland, where he was attending an international conference of mathematicians.

He founded the field of discrete mathematics, the foundation of computer science, and was known for his work in numbers theory, theory of sets and probability theory.

Born in Budapest, Hungary, he moved to Britain in 1934 and settled in the United States four years later.

A member of Britain's Royal Society and the national academies of Hungary, the Netherlands, the United States, Australia and India, he traveled all over the world to discuss mathematical problems with other academics.
