BLACK SOCIAL HISTORY : AFRICAN AMERICAN PROFESSIONAL BOXER FLOYD PATTERSON :

Patterson turned pro and steadily rose through the ranks, his only early defeat being an eight-round decision to former Light Heavyweight

Champion Joey Maxim on June 7, 1954, at the Eastern Parkway Arena in Brooklyn, New York. Most people think Patterson did enough to win, and Maxim's greater fame at the time helped to sway the judges
Although Patterson fought around the light heavyweight limit for much of his early career, he and manager Cus D'Amato always had plans to fight for the Heavyweight Championship. In fact, D'Amato made these plans clear as early as 1954, when he told the press that Patterson was aiming for the heavyweight title.However, after Rocky Marciano announced his retirement as World Heavyweight Champion on April 27, 1956, Patterson was ranked by The Ring magazine as the top light heavyweight contender. After Marciano's announcement, Jim Norris of the International Boxing Club stated that Patterson was one of the six fighters who would take part in an elimination tournament to crown Marciano's successor. The Ring then moved Patterson into the heavyweight rankings, at number five.

After beating Tommy "Hurricane" Jackson in an elimination fight, Patterson faced former Light Heavyweight Champion Archie Moore on November 30, 1956, for the World Heavyweight Championship. He beat Moore by a knockout in five rounds and became the youngest World Heavyweight Champion in history, at the age of 21 years, 10 months, 3 weeks and 5 days. He was the first Olympic gold medalist to win a professional Heavyweight title.

Ingemar Johansson knocks out Floyd Patterson and becomes boxing heavyweight champion of the world, June 26, 1959.

After a series of defenses against fringe contenders (Hurricane Jackson, Pete Rademacher, Roy Harris and Brian London), Patterson met Ingemar Johansson of Sweden, the number one contender, in the first of three fights. Johansson triumphed over Patterson on June 26, 1959, with the referee Ruby Goldstein stopping the fight in the third round after the Swede had knocked Patterson down seven times. Johansson became Sweden's first World Heavyweight Champion, thus becoming a national hero as the first European to defeat an American for the title since 1933.
Patterson knocked out Johansson in the fifth round of their rematch on June 20, 1960, to become the then first man to in history to ever regain the Undisputed World Heavyweight Championship. Johansson hit the canvas hard, seemingly out before he landed flat on his back. With glazed eyes, blood trickling from his mouth and his left foot quivering, he was counted out. Johansson lay unconscious for five minutes before he was helped onto a stool.
A third fight between them was held on March 13, 1961 and while Johansson put Patterson on the floor, Patterson retained his title by knockout in the sixth round to win the rubber match in which Patterson was decked twice and Johansson once in the first round. Johansson had landed both right hands over Floyd’s left jab. After getting up from the second knockdown Floyd abandoned his jab and connected with a left hook that knocked down Johansson. After that, Patterson came on with a strong body attack that wore down Johansson. In the 6th round, Johansson caught Patterson with a solid right. But the power in Ingemar’s punches was gone. Patterson won the fight in the 6th round by knockout.
