Which three sporting heroes died in the 1950's?

In the 1950s, three notable sporting heroes who passed away were Baseball legend Lou Gehrig, who died in 1941 but became a symbol of courage in the 1950s due to his legacy; boxing champion Joe Louis, who died in 1981 but had a significant impact during the 1950s; and football star and coach Paul Brown, who died in 1991 but was influential in shaping the game during that decade. However, a more direct answer would be the deaths of iconic figures like the boxer Rocky Marciano, who died in a plane crash in 1969, and the famous golfer Ben Hogan, who survived a serious car accident in 1949 but continued to influence the sport until his death in 1997.
