Mr.Hebert

Georges Hébert (1875-1957)
A French soldier and philosopher of physical culture. He was inspired by the athletic qualities of natives he encountered while serving in the French Navy in Africa. He developed a philosophy of physical culture from his observations called the Natural Method. Part of that philosophy had an emphasis on training by obstacle courses. These obstacle courses, known as Parcours Du Combattant, have become part of military training systems throughout the world. Part of Hebert's philosophy was that physical training should strengthen one’s moral fabric. His motto was "Être fort pour être utile," be strong to be useful. This is an important foundation of parkour philosophy.
Just a little on the man that helped Le-Parkour come to light.
