Dr. Auguste Rollier (The Sun Doctor)
In 1903 Swiss doctor Auguste Rollier opened his “sunlight clinic,” which featured an enormous solarium on the roof and developed a slow, careful tanning process for new or especially feeble patients. Here, the ultraviolet (UV) component in sunlight, acting on the skin—now understood as carcinogenic in high doses — was the presumed mode of action, although the patients may also have benefitted from the mood and energy boosts of light to the eyes.
