List of Famous people with last name Hagler

Marvelous Marvin Hagler was an American professional boxer and film actor who competed in boxing from 1973 to 1987. He reigned as undisputed middleweight champion from 1980 to 1987, making twelve successful defenses of that title, and holds the highest knockout percentage of all undisputed middleweight champions, at 78%, while also holding the Third-longest unified championship reign in boxing history at twelve consecutive defenses. At six years and seven months, his reign as undisputed middleweight champion is the second-longest of the last century, behind only Tony Zale, whose reign included several years of inactivity during his service in World War II. In 1982, annoyed that network announcers often did not refer to him by his nickname "Marvelous", Hagler legally changed his name to "Marvelous Marvin Hagler".
