[1] During his medical training, he worked for a time at the hospice at Brévannes under the tutelage of Dr Paul Carton,[2] where he gained his knowledge of natural treatments.
In 1923, together with his brother André, he launched the magazine La Vie Sage, monthly review of naturism and psychic education - which took the title Naturisme in 1930.
Durville's brother, Henri, besides his publishing activities, had partnered with a former disciple of Dr Paul Carton, Dr. Viard, to found a psycho-naturist Medicine Institute in Neuilly-sur-Seine.
The combined influence of Carton's natural medicine and the "psychological medicine" of Hector and Henri Durville led the brothers, Gaston and André, to develop a "psycho-naturism" therapeutic method based on the combined use of physical agents, diet, massage, physical exercise, air baths, water and light, psychic agents, magnetism, hypnosis, mental suggestion and psychotherapy.
The brothers became convinced that the practice of medicine in specialized institutions was not sufficient ensure good health, and so they began to find news was to popularize the benefits of naturism.
