Carlos Gracie
Carlos Gracie was a Brazilian martial artist who is credited with being one of the primary developers of Brazilian Jiu-Jitsu. Along with his younger brother Hélio Gracie and fellow students Luis França and Oswaldo Fadda, he helped develop Brazilian jiu-jitsu based on the teachings of Mitsuyo Maeda in Kano Jiu-Jitsu and is widely considered to be the martial-arts patriarch of the Gracie family. He purportedly acquired his initial knowledge of Jiu-Jitsu by studying in Belem under Maeda and his students. As he taught the techniques to his brothers, he created a martial arts family with Hélio and with other members of the Gracie family who provided key contributions to the style and development, eventually creating their own self defence system named Gracie Jiu-Jitsu.
