Dr. Moshe Feldenkrais, is probably the most influential figure when talking about Israeli hand-to-hand combat systems.
As a young boy in Belarus, Moshe Feldenkrais gained practical street fighting experience from local brawls caused by anti-Semitism. At age 14 he decided to leave his home, and immigrated by himself, on a six months journey (most of it by foot) to Israel.
While living in Israel, Feldenkrais became frustrated from the low effectiveness of Ju-Jitsu techniques which were used in real combats. He decided, to develop different techniques and concepts, which will achieve better results.
Moshe discovered a new concept which he coined ‘unconscious reaction‘. This concept was the foundation for his improved combat method.
The Hagana command, identified his potential and granted him a three years budget to train their members. Following this experience, Feldenkrais published a book named ‘Ju-Jitsu and Self Defense’, a book which was the outcome of his insights and experience in hand-to-hand combat, and, his discovery of the ‘unconscious reaction‘ concept. His book and concept, laid the foundation for an improved fighting regimen and better training methods.
In Feldenkrais book, there are elements which later were identified with Sport Magen, Kapap and Krav-Maga.
