# Paul Erdős

**Paul Erdős** (Hungarian: **Erdős Pál** [ˈɛrdøːʃ paːl]; 1913–1996) Hungarian mathematician of Jewish ancestry, famous for being the coauthor of hundreds of mathematical papers and for offering prizes for solutions of many mathematical problems. Most famous mathematicians today have coauthored at least one paper with one of Erdős' coauthors (cf. Erdős number). Many problems in Richard K. Guy's book *Unsolved Problems in Number Theory* mention prizes offered by Erdős for their solution.

Both his father and mother taught mathematics and physics. Early on it was clear he was a prodigy, figuring out the concept of negative numbers at age 3. Interested only in mathematics, Erdős "never owned a home, a car, or a checkbook, and never had a family or an address."^{[1]}
