Which mathematician is that?
Grigorij Parelman is a Russian mathematician who in 2003 proved (confirmed in 2006) Thurston's geometrization conjecture. This consequently solved in the affirmative the Poincaré conjecture. In 2006 he was offered the Fields Medal and a million $ along with it, but he declined the award, stating: "I'm not interested in money or fame; I don't want to be on display like an animal in a zoo."
