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". Early years Olson was born in Honolulu, Territory of Hawaii to a Portuguese mother and a Swedish father, hence his other nickname "The Hawaiian Swede". Like many boxers, Olson decided to take up the sport after getting into fights on the streets. Olson received training from boxers who were stationed in Hawaii during World War II, and it was during this period that he picked up his two trademark tattoos. Using a fake identity card Olson obtained a boxing license at the age of 16. His earliest fights were in his native Kalihi, Hawaii. He had won his first three contests, two by knockout, before his true age was discovered. During 1945, Olson ran off to San Francisco to continue his boxing career. By the time he was 18, he had amassed a record of 13 successive wins (10 by KO). Even at this stage his power and huge reserves of stamina were clear, as was his rather average skill. Professional career The first real test of Olson's career came on March 20, 1950, Olson's record at this point was 40 wins and 2 losses, against the Australian Dave Sands. Olson lost to a close points decision in Sydney. Seven months after this Olson had his first fight against Sugar Ray Robinson, for the lowly regarded Pennsylvania State World Middleweight Title. Olson, who was widely seen as a slow starter, failed to get into the fight, even though Robinson was not having one of his best fights. Olson managed to hold on for 11 rounds before being knocked out. Despite his great record it was clear that Olson was still too inexperienced to be fighting at that level. A year after his loss to Robinson, Olson managed to get a rematch against Dave Sands. This fight was the first to be televised coast-to-coast in America. However, Sands once again proved too much for Olson, he again won by unanimous decision. On March 13, 1952 Olson fought Robinson again, this time for the world middleweight title. Robinson, who had lost and regained the title against Randy Turpin in his previous two fights,
