Mathematicians Settle the Erdős Coloring Conjecture

WIRED 

In the fall of 1972, Vance Faber was a new professor at the University of Colorado. When two influential mathematicians, Paul Erdős and László Lovász, came for a visit, Faber decided to host a tea party. Erdős in particular had an international reputation as an eccentric and energetic researcher, and Faber's colleagues were eager to meet him. "While we were there, like at so many of these tea parties, Erdős would sit in a corner, surrounded by his fans," said Faber. "He'd be carrying on simultaneous discussions, often in several languages about different things."
