The 1964 gold medalist was Poland’s Józef Grudzień and since Tokyo he had won the 1967 European Amateur Championship in this class, after taking a silver medal in that event in 1965. In 1964 Grudzień had defeated American Ronnie Harris in the semi-final. The final in 1968 would again come down to Grudzień against Ronnie Harris from the United States, but oddly enough, this was a different Ronnie Harris than had represented the USA in 1964. This Ronnie Harris was a three-time AAU Champion (1966-68), a two-time Golden Gloves champion, and had won the 1967 Pan American Games gold medal. He won a unanimous decision in Mexico City over Grudzień to win the 1968 gold medal. Harris turned professional after the Olympics, fighting through 1982 and finishing with a career record of 35 wins and 2 losses. Unfortunately his two losses came in his only two title fights, losing a bout for the WBA/WBC middleweight title to Hugo Corro in 1978, and losing to Sammy NeSmith in 1980 for the NABF middleweight crown.
