In which year was this American heavyweight boxer born who was active in the 1950s through the 1970s, and was defeated by the former Canadian professional boxer George Chuvalo?
George Chuvalo George Louis Chuvalo, CM (born September 12, 1937) is a retired Canadian professional boxer who was a five-time Canadian heavyweight champion, and two-time world heavyweight title challenger. Chuvalo, who is considered by many to have one of the best chins in boxing history, was never knocked down in his amateur career or his 93-fight professional career and was ranked #4 on ESPN's greatest chin in boxing history list. Chuvalo lost to Hall of Fame heavyweights such as Floyd Patterson, Muhammad Ali, Joe Frazier and George Foreman, but was credited for his spirited performances. He did defeat top contenders such as Yvon Durelle, Doug Jones, Jerry Quarry and Cleveland Williams. He fought for the world title twice, losing a controversial decision to Ernie Terrell and another decision in his first fight with Ali.
Buster Douglas James "Buster" Douglas (born April 7, 1960) is an American former professional boxer who competed from 1981 to 1990, and 1996 to 1999. He is best known for his stunning upset of Mike Tyson on February 11, 1990 in Tokyo to win the undisputed heavyweight title. At the time Tyson was undefeated and considered to be the best boxer in the world, as well as one of the most feared heavyweight champions in history due to his domination of the division over the previous three years. The only casino to make odds for the fight (all others declining to do so as they considered the fight such a foregone conclusion) had Douglas as a 42-to-1 underdog for the fight, making his victory, in commentator Jim Lampley's words, "The biggest upset in the history of heavyweight championship fights." Douglas held the title for eight months and two weeks, losing on October 25, 1990 to Evander Holyfield via third-round knockout, in his only title defense.
