Title: Living Legend
A "Living Legend" is a person whose notoriety has become widespread during their own lives, such that it touches on people even well outside their normal sphere of influence. Warren Buffet Tiger Woods, Michael Jordan, and Bill Gates would be obvious examples. The term is usually not applied to someone automatically famous for a position, such as an actor, or the US President, which automatically comes with a measure of fame and notoriety. (Say if, however, a president or former president became a championship golfer, then they might achieve "Living Legend" status). The term "Household Name" is also often used interchangeably.
