Bobo Olson, American boxer (d. 2002)
Carl Olson (July 11, 1928 – January 16, 2002) was an American boxer. He was the World Middleweight champion between October 1953 and December 1955, the longest reign of any champion in that division during the 1950s.
His nickname, Bobo, was based on his younger sister's mispronunciation of "brother".
