In 1902, a series of philosophical papers was published in Germany by Dr. Heinrich Pudor under the pseudonym Heinrich Scham, who coined the term "Nacktkultur". In 1906 he went on to write a three-volume treatise with his new term as its title, which discussed the benefits of nudity in co-education and advocated participating in sports while being free of cumbersome clothing. Richard Ungewitter ("Nacktheit", 1906, "Nackt", 1908, etc.) proposed that combining physical fitness, sunlight, and fresh air bathing, and then adding the nudist philosophy, contributed to mental and psychological fitness, good health, and an improved moral-life view. Major promoters of these ideas included Adolf Koch and Hans Suren. Germany published the first journal of nudism between 1902 and 1932.
