In different sports when a sportsman wins four crowns, titles, medals, belts or another distinctions is called a Quadruple Champion.
The first ever man to earn that enormous distinction was Thomas Hearns on October 29, 1987. Hearns won his first four titles at the following divisions: Welterweight (147 lbs), Light Middleweight (154 lbs), Middleweight (160 lbs) and Light Heavyweight (175 lbs). By later winning a super middleweight title, he also became the first to win world titles in five weight divisions.
The second man was Ray Charles Leonard, who on November 7, 1998 won his first championships at Welterweight (147 lbs), Light Middleweight (154 lbs), Middleweight (160 lbs), Super Middleweight (168 lbs) and Light Heavyweight (175 lbs). There are five titles in five divisions but his case is extremely rare: Leonard fought for two different belts in two different weight divisions the same night: Super middleweight (168 lbs) and Light heavyweight (175 lbs) against Don Lalonde so any of the titles can be attached as his fourth title.
The legendary Leo Gamez was the first champion to win all the lightest divisions from Minimumweight (105 lbs), Light Flyweight (108 lbs), Flyweight (112 lbs) to Super Flyweight (115 lbs). Gamez did it on October 9, 2000.
Some boxers have managed to win four titles and become Quintuple Champions.
Yvan Muller is the only person to win four World Touring Car Championships.
