William Kwai-sun Chow

William Kwai-sun Chow (July 3, 1914 – September 21, 1987, AKA William Ah Sun Chow-Hoon) was instrumental in the development of the martial arts in the United States, specifically the family of styles referred to as kenpo/kempo.

Born in Honolulu, but raised in Hana, Hawaii, Chow was the third of sixteen children and the first son born to Chow Hoon (AKA Ah Hoon-Chow) and Rose Kalamalio Naehu. Chow's father came to Hawaii at the age of 18 and worked in a laundromat as a laborer. His mother was of Hawaiian descent. One of his brothers, John Chow-Hoon, would also become a well–known martial artist. Chow left school at age eleven when he was in the sixth grade. Provided by Wikipedia
