 In 1947, Adriano Emperado (Kosho Shorei-ryu Kenpo and Escrima), Peter Young Yil Choo (Tang Soo Do, Shotokan Karate and Boxing), Joseph Holck (Sekeino-ryu Judo), Frank F. Ordonez (Danzan-ryu Jujutsu), and George "Clarence" Chuen Yoke Chang (Chu'an Fa Kung-Fu), came together and called themselves the Black Belt Society.They began training together and exploring the weaknesses and developing the strengths of each martial art to create a fighting style that did not suit the ancient warrior but the American citizen to help him or her in their fight against the common criminal.After the other four founders were drafted off into the Korean War, they left Emperado to start the first Kajukenbo school at the Palama Settlement Gym in 1950.
