I had the pleasure of meeting Mr. Wolf and taking his Bartitsu class at ISMAC in Detroit over Memorial Day weekend. He struck me as a very capable and insightful instructor. It is also interesting to learn of Barton-Wright and the foundation of Bartitsu, as it was one of the first attempts in the West to cross-train in Eastern and Western martial arts.
