In 1903, the Nobel Prize in medicine was awarded to Danish Physician, Niels Ryberg Finsen, for his work in treating Smallpox and Tuberculosis with light.
Further interest in the field was pioneered by Professor Endre Mester, a Hungarian physician and scientist, who in 1967 successfully used light to heal wounds and regrow hair in mice and people.
NASA also experimented frequently with light in the 1970's and 1980's and successfully used LED light to grow flowers in space.Today, light is used to pre-prime patients prior to surgery (including cardiovascular surgery) as well as for several neurodegenerative disorders.
