On a boxing tour in England at the start of World War 1, Joe was held as a resident alien in an internment camp. While in the camp, he started a training program working with his fellow detainees. Shortly thereafter, his work brought him to the attention of the camp leaders, and he was assigned as a hospital orderly to help patients rehabilitate. He worked with his group of thirty patients daily, assisting them to focus on even the smallest movements, thereby helping them to work their bodies back into better health and recovery. After the war ended, he immigrated to the United States, and continued to develop and refine his “Contrology” teaching format. He worked with clients from all walks of life, but made an especially strong impression on the dance community.
