While studying the beneficial effects of ultraviolet light on athletes, German scientist Friedrich Wolff noticed an interesting side effect - tanned skin. Realizing the appeal of a beautiful tan, Wolff founded the indoor tanning industry. His research led to development of indoor tanning equipment and lamp technology. Called "the father of indoor tanning," Wolff brought his European technology to the United States in 1978. He set the standard for the industry with specialized lamps and a reflector system that was ideally suited to indoor tanning. Today, the company operates in North America and Western Europe
, and has patent licensees in Belgium, Canada, Germany, Sweden, Switzerland and the United States.
