Bobo Olson (Paperback)

High Quality Content by WIKIPEDIA articles! Carl Olson 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, although he is probably best remembered for his three knockout losses against Sugar Ray Robinson. His nickname, Bobo, was based on his younger sister's mispronunciation of "brother."
