Let us join our hands today in remembering Niels Ryberg Finsen (1860--1904), the father of heliotherapy. Born in the Faroe Islands and trained in Copenhagen, he was a frail medical student who once wondered how he could grow stronger simply by stepping into sunlight--an observation that led him to uncover how specific wavelengths could kill infection, regenerate tissue, and heal chronic conditions. He earned the 1903 Nobel Prize for curing the "incurable" lupus vulgaris with concentrated-light therapy. Finsen believed the sun is an essential part of the human operating system--perhaps the greatest healing force known to man--powerful enough for the pharmaceutical goblins to erase him from the history books.
