Ngô Đồng

Ngô Đồng (born South Vietnam - died 15 May 2000), known also by the Japanese title O Sensei, was a Vietnam-born naturalised American entomologist and martial arts instructor. He is chiefly known as the founder and grandmaster of the international school of Cuong Nhu Oriental Martial Arts. Having served as a college president in South Vietnam before the fall of Saigon in 1975, he spent time in a re-education camp until escaping in a small boat. He taught entomology at the University of Florida for the remainder of his career, guiding the international Cuong Nhu martial arts community at the same time. Provided by Wikipedia
