Protect yourself with a rolled up magazine!

Master Ronald Duncan is considered by some to be the father of American ninjitsu.

Duncan has also studied a number of different styles such as judo, boxing, Hakko Ryu jujutsu, Dai-Nippon Jujutsu Ryu, Sosuishi Ryu, Kin Dai Gakko Ryu, aikido, aikijujutsu, kempo, and kobujutsu.

Born in Panama. Professor Ronald Duncan began training in boxing at the age of seven. Since Professor Ronald Duncan grew up in an area where many of the elite military forces of that country were training in jungle warfare, he learned at an early age to read the signs of nature for directions in and out of the jungle.

It was the beginning of a long and very involved career in many aspects of the martial arts.

Ronald Duncan went on to serve in the United States Marine Corp where he was a member of the USMC Judo team and earned one of his earliest black belt rankings.

Professor Duncan went on to earn a black belt in several other disciplines such as Hakko Ryu Jujitsu, Dai-nippon Jujitsu Ryu, Sosuishi Ryu, Kin Dai Gakko Ryu, Aikido, Aiki-Jujitsu, Kempo, Kobujitsu (weaponry), and Shinobino-jitsu (popularly known as Ninjitsu).

His teachers were all legendary men; Charlie Neal, Ernie Cates, Tatsuo Uzaki, and Don Draeger.

Black Belt magazine referred to Duncan as a pioneer in the field of ninjitsu. Duncan began teaching Koga Ryu in 1959. Duncan was the first American to demonstrate ninjitsu to the American public in 1967.

Duncan, along with Stephen K. Hayes and Masaaki Hatsumi, helped to popularize Ninjutsu in the United States in the 1970s and the 1980s. All three attended the 1987 Ninja Summit.
