description: "Gustav Jäger was a German physician, naturalist and hygienist. He was a professor of zoology and physiology at the Stuttgart veterinary medicine school and at the Stuttgart Polytechnic. In his writings and teachings he advocated various measures for what he considered as healthy clothing and lifestyle. He promoted the use of woolen clothes that he termed as \"normal clothing\" which he claimed were the closest to natural animal covering and allowed the \"soul\" made of chemical constituents from the body to release some of the harmful portions which one could detect in the form of fragrances."
