What is Jun Fan Jeet Kune Do?



Whether you are an instructor currently teaching, a student or practitioner, or simply an individual who is genuinely interested in learning more about Bruce Lee or his martial art and philosophy, the Jun Fan Jeet Kune Do Nucleus' goal remains the same: to help people around the world to gain a better understanding of both Bruce Lee and his art and philosophy. Jun Fan Jeet Kune Do is a non-profit educational organization established for the purpose of promoting understanding through providing the means for those seeking information about the art of Bruce Lee.

The Organization

Jun Fan Jeet Kune Do is a non-profit corporation formed for the sole purpose of preserving and perpetuating Bruce Lee's art and philosophy which he called Jeet Kune Do. Its existence began in Seattle, Washington on January 10, 1996 when Linda Lee Cadwell invited many of Bruce Lee's students among others to discuss the state of her late husband's martial art with her and Shannon, their daughter. Its Board of Directors is the Jun Fan Jeet Kune Do Nucleus and is currently comprised of 13 original students, 5 second generation students, Bruce Lee's widow and daughter.

Jun Fan Jeet Kune Do functions as an educational organization to inform the martial arts community and the public worldwide about Bruce Lee's body of work. The Nucleus feels that Bruce Lee's philosophy and way of life represent an inspiring model of thought and can motivate others to develop their full physical and spiritual potential. In order to maintain the integrity of Jun Fan Jeet Kune Do, the Nucleus wants to give a clear and accurate picture of Bruce Lee's evolution in the martial arts.  

It is this set of basic technical, scientific, and philosophical principles - the foundation of Bruce Lee's art - that the Jun Fan Jeet Kune Do Nucleus seeks to preserve. Ideally, every person who understands the basic principles of Jun Fan Jeet Kune Do should end up expressing himself uniquely, that is, he or she will absorb techniques that are personally useful and reject what is unsuitable while adding what is specifically their own. When that individual reaches the stage of artlessness, or the height of simplicity, then truly they will have found their own expression of Jun Fan Jeet Kune Do, different from anyone else's. But one cannot reach that pinnacle without having assembled the building blocks.  

The Nucleus decided that Jun Fan Jeet Kune Do would be an organization established for the purpose of promoting understanding through providing the means for those seeking information about the art of Bruce Lee. The Nucleus plans to implement its educational program by means of seminars, group and individual instruction, and the publishing of written, visual, and audio materials. Towards this end, the Nucleus will build a membership of persons skilled and knowledgeable in Jun Fan Jeet Kune Do who will form the vanguard of the future and will continue the pattern of growth toward greater spiritual awareness initiated by Bruce Lee.  

Jun Fan Jeet Kune Do is a non-profit corporation. Any revenue received by the organization through seminars, memberships, publications will be utilized to further the educational goals of the corporation. Jun Fan Jeet Kune Do (JFJKD) is a trademarked name and cannot be used legitimately by any persons unauthorized to do so by the Jun Fan Jeet Kune Do Nucleus. Jun Fan Jeet Kune Do is not associated with any other organization using the name Jeet Kune Do.


The stated goals of the Jun Fan Jeet Kune Do Nucleus are as follows:

  1. To promote and perpetuate the art of Jun Fan Jeet Kune Do and to foster respect for its founder, Bruce Jun Fan Lee.
  2. To disseminate information to the martial arts community and the public about the art and science of Jun Fan Jeet Kune Do based upon Bruce Lee's written notes and records and the personal experiences of his original students.
  3. To serve as a living repository of all of the various aspects of Jun Fan Jeet Kune Do, including physical/technical training, historical foundation, scientific basis and philosophical/mental spiritual learning.
  4. To maintain high standards of clarity with regard to the dissemination of information concerning the art and its founder.
  5. To establish a Code of Ethics calling for mutual respect between members and for instructors and practitioners of other martial arts disciplines.
To give recognition to legitimate instructors and practitioners of Jun Fan Jeet Kune Do.

The Jun Fan Jeet Kune Do Name

A major resolution was adopted (January 10-11, 1996) concerning the name of the art in order to quell the confusion which currently exists. Shannon Lee Keasler suggested that the terms Jun Fan and Jeet Kune Do be combined to represent her father's art from this day forward. By unanimous agreement, the term "Jun Fan Jeet Kune Do" was chosen.

Since it was agreed that both Jun Fan Gung Fu and Jeet Kune Do cannot and should not be separated, it was decided that the two terms should be combined. In this way, the Nucleus would distinguish the complete body of technical and philosophical knowledge studied and taught by Bruce Lee during his lifetime. Jun Fan Jeet Kune Do is unique in its approach to the study of combative arts in that it combines martial aspects with an encompassing philosophy and a scientific basis. Hence, Jun Fan Jeet Kune Do is all-encompassing in that it endeavors to cover all of the various facets of Bruce Lee's art, philosophy, and history.

Points of Clarification

January 1, 1997

Since the formation of the Jun Fan Jeet Kune Do Nucleus in January 1996, a great deal of misinformation has been circulated concerning our organization and what it is all about. Most of this misinformation has been in the form of speculation and rumor. It has been the position of the Nucleus not to respond, but instead to maintain a positive stance as we move forward. If you are interested in finding out what the Nucleus is all about, read the following information:  

The JFJKD Nucleus is a synergistic group of original students of Bruce Lee and second generation students united together and dedicated to preserving and perpetuating Bruce Lee's legacy as a martial artist, teacher, and philosopher.  

The Charter Members of the Nucleus included:

Linda Lee Cadwell, Shannon Lee Keasler, Taky Kimura, Allen Joe, George Lee, Bob Bremer, Richard Bustillo, Steve Golden, Larry Hartsell, Dan Inosanto, Herb Jackson, Pete Jacobs, Daniel Lee, Jerry Poteet, Ted Wong, Greglon Lee, Chris Kent, Tim Tackett, and John Little.


Notes: -- Dan Inosanto has since chosen not to play an active role in the Nucleus. However, he is recognized and highly regarded by the Nucleus as an instructor of JFJKD.

-- In August, 1996, following a unanimous vote, Tommy Gong was invited to become a member of the Nucleus.


The Nucleus would like to clarify our position on the following points:

1) The Nucleus does not certify instructors to teach JFJKD or test those who are currently teaching Jeet Kune Do, Jun Fan Gung Fu, Jun Fan Martial Arts or any other art. Our function is to serve as an educational and inspirational organization, to act as a living repository or information about Bruce Lee and his art, and to promote personal excellence and growth. We do not see ourselves as the only group of people having this goal, and we welcome the combination of synergistic energies between the Inosanto Association, the Nucleus and all others having a desire to see Bruce Lee's work perpetuated. Greater progress can be made by working together rather than in opposition.


2) The Nucleus will recognize (not certify) qualified instructors of JFJKD. Recognition means that the Nucleus acknowledges that an individual has a high degree of scholarship in JFJKD. Individuals are recommended for recognition by their instructors. Recognition is not the equivalent of a license to teach JFJKD; that privilege is granted between instructor and student. The sole purpose of this recognition process for JFJKD is to serve as a reference source when interested persons ask for information about the art and philosophy of Bruce Lee. Beyond that, we have no interest in criticizing or making judgments about the abilities of instructors or the value of other arts.


3) The Nucleus has no desire to diminish the importance of contributions made by Dan Inosanto or any other individual to Jeet Kune Do. We hope you remember that when the name, the goals, and the Code of Ethics of JFJKD were established, Dan Inosanto was present and took an active role in its formation. It was Dan's choice to resign from the group, and upon leaving he stated that we share the common goal of protecting and preserving Bruce's art. He wished the Nucleus well and hoped that unfortunate political controversies could be put to rest. This is our most earnest hope.


4) The Nucleus has high regard for Dan Inosanto. Regardless of what you may have heard, the Nucleus respects Dan Inosanto as a skilled and knowledgeable martial artist, as Bruce's assistant instructor in the L.A. Chinatown School, and as sifu of many Nucleus members. In fact, several Nucleus members were certified in Jeet Kune Do or Jun Fan Gung Fu under Dan Inosanto and have taught classes for Dan. This certification plus their personal experience with Bruce Lee only enhances the contribution they can make to preserving his art. In addition, some Nucleus members did receive certificates of various levels of accomplishment directly from Bruce Lee. It is unfortunate that Dan Inosanto decided not to be a part of the Jun Fan Jeet Kune Do Nucleus because we recognize that his contribution and that of many of his students is of great value. The contribution of all students of Jeet Kune Do should be combined for the benefit to future generations.


5) Jun Fan Jeet Kune Do is a registered non-profit corporation; any charges for services and events will only cover expenses and cannot, by law, enrich any members of the organization. The name Jun Fan Jeet Kune Do was chosen to differentiate it from all other teachings and interpretations of Jeet Kune Do, of which there are many around the world. Our desire is that the term Jun Fan Jeet Kune Do should refer only to the teaching of Bruce Lee and not to expanded interpretations of his art by individual practitioners, be they members of the Nucleus or not.


In summary, JFJKD seeks only to do its part in sharing and recording the experiences of its members. We have no intention of diminishing, stopping, criticizing, or judging anyone else's contribution to Bruce's art. As stated at our inaugural meeting in January 1996 in Seattle, our purpose is to bring people together to share the knowledge and experience.



In the Spirit of Jun Fan Jeet Kune Do,

The Jun Fan Jeet Kune Do Nucleus
