STOCKHOLM, Sweden — Ingemar Johansson, the Swede who stunned the boxing world by knocking out Floyd Patterson to win the heavyweight title in 1959, has died, a longtime friend said Saturday. Johansson was 76.

Johansson died at a nursing home in Kungsbacka on the Swedish west coast, said Stig Caldeborn, a close friend who sparred with Johansson when they were in their teens.

Johansson knocked out Patterson in the third round at Yankee Stadium on June 26, 1959, to win the heavyweight title. He floored the American seven times in the third round before referee Ruby Goldstein stopped the fight 2:03 into it.

Patterson avenged the upset loss a year later in the rematch in New York, knocking Johansson out in the fifth round. In March 1961, the Swede floored Patterson twice in Miami before being knocked out in the sixth round of the rubber match.
