Although there were varying degrees of crossover from one evolving method to another, there were at least five clear and distinct philosophies and/or styles created by Ed Parker Sr.
1. Kenpo Karate
What Ed Parker was doing when he arrived on the mainland, first as a brown and later as a black belt opening shop in Pasadena around 54. Wrote the book of the same name and published it in 1961. Teachers like Chuck Sullivan draw from this era.
2. Chinese Kenpo
When Ed Parker discovered the vast knowledge available and embraced the Chinese Arts while studying with and under Ark Wong and Haumea Lefiti. Also where he met Jimmy (James Wing) Woo, and Danny Inosanto. Here he also broke with the established "Yudansakai" governing board. During this period, he wrote "Secrets of Chinese Karate" and published it in 1963. Notice the compressed time . People like Frank Trejo's instructor, Steve Hearring still teach this perspective in Pasadena Ca..
3. American Kenpo
Began the codification process of his early understandings of Chinese Kenpo into a distinct evolving American interpretation. Here he dropped all Japanese - Chinese language and non-essential non-American cultural accoutrements. Notice the lack of the word "karate," considered an insult to the Chinese. Some like Dave Hebler draw from the beginnings of this version.
4. Ed Parker's American Kenpo Karate
A series of personal issues causes Ed Parker to decide to enter the commercial marketplace and expand in the second half of the sixties. Looking for a method that differed from the Kenpo franchises that preceded him that he felt were flawed, he drew upon his many "transfer" black belts from other styles. Stumbling upon "motion" as a base concept, it allowed him to create loose conceptual guidelines for already competent black belts. This further gave him the freedom to travel conducting seminars, belt tests, and selling, while seeing the majority of his "students" two or three times a year. Most of the well-known black belts came up under this system. Some came very late in the eighties and is the reason they are not on ParkerÂ’s published Family Tree. The rest came after Parker's death.
This was what he was sharing with a few private students in an effort to cash in on the publicity of Larry Tatum's student
Jeff Speakman's movie, "Perfect Weapon." He hoped to rekindle a chain of schools that he directly controlled.
5. Ed Parker's Personal Kenpo
The ever-evolving personal art of Ed Parker that included elements left out of his commercial diversion or off shoots. However, in reality it is the "American Kenpo" Parker was himself utilizing before he passed away that was still evolving. Others that he may have taught may have other names for it, but to understand it, a person would have had to evolve with Parker because of a lack of its hard codification.
