For you see, there once was a boy who loved math. His name was Paul and he lived in Budapest, Hungary in 1913. As a child, Paul adored numbers, and theorems, and patterns, and tricky ideas like prime numbers. As he got older he grew to be the kind of guy who wanted to do math all the time! Paul was a great guy and a genius and folks loved having him over, but he was utterly incapable of taking care of himself. Fortunately, he didn’t have to. Folks would take care of Paul and in exchange he would bring mathematicians together. The result of these meetings was great strides in number theory, combinatorics, the probabilistic method, set theory, and more! Until the end of this days (when he died in a math meeting) Paul loved what he did and he loved the people he worked with. “Numbers and people were his best friends. Paul Erdős had no problem with that.”
