The American Gymnosophical Association (AGA) is believed to have been started in the early part of the 20th Century, inspired by the idea that nude sunbathing was a healthy way of life. This belief seems to have first gained popularity in Germany in the 1890s following the publication of two influential books, Heinrich Pudor's The Cult Of The Nude, and Heinrich Ungewitter's Die Nacktheit (Nakedness), a utopia of nude living.
