He is the author of a book on the subject of Jiu Jitsu titled "Brazilian jiu-jitsu: For Experts Only," which includes his student Julio "Foca" Fernandez. The oldest son of Carlos Gracie, who founded Gracie jiu-jitsu in Rio de Janeiro during the 1920s, Carlson reigned as world champion for thirty years covering the '50s, '60s and '70s. Carlson catapulted to fame at the age of 23 when he avenged the defeat of his uncle Helio Gracie. A former student of Helio's, Waldemar Santana, had defeated the much older Helio during a match in 1955. That match lasted four hours. Carlson's rematch with Santana in 1956 was a much shorter affair: four rounds of vicious vale-tudo combat came to draw. After teaching at his uncle's academy for several years, he opened his own, where over the past thirty years many of the greatest names in jiu-jitsu and Mixed Martial Artists have trained as members of the famed Carlson Gracie Arrebentacao Team. Carlson's influence on no-holds-barred fighting is extensive as well, for the style of jiu-jitsu he taught at his academy was distinct from that being taught by Helio. While Helio's brand of jiu-jitsu emphasized defensive techniques aiming to allow the smaller and weaker to defeat the stronger opponent, Carlson and his brothers Carley Gracie and Rolls Gracie favored a much more active, 'warrior style' of jiu-jitsu that encouraged physical prowess and barraging your opponent with a series of attacks. Carlson Gracie died on February 1, 2006, in Chicago, Illinois, of heart failure, apparently the result of complications of kidney stones (and possibly his pre-existing diabetes), following a hospitalization of several days. At the time of his death he was a ninth degree red belt and was referred to as Grandmaster. A bronze statue honoring Gracie will be installed next to his gym in Rio de Janeiro on August 12, 2019. There's a controversy story that Geo Omori would have trained Carlos Gracie.
