Paul Erdős was a Hungarian mathematician known for his extensive contributions to number theory, combinatorics, and graph theory. Born on March 26, 1913, he published more than 1,500 mathematical papers, many in collaboration with other mathematicians, and became famous for his nomadic lifestyle, traveling around the world to work with peers. Erdős's work on the Erdős number concept also popularized the idea of collaboration in mathematics.
