Ultraviolet light animal tests, 1926 C017 / 7867
Ultraviolet light animal tests. Researchers for the United States Department of Agriculture carrying out ultraviolet (UV) light therapy on white rats. Ultraviolet light is the portion of the electromagnetic spectrum between visible light and X-rays. UV rays occur in sunlight and are responsible for sunburn. They have beneficial effects when used to treat skin conditions (a form of phototherapy). This photograph, from 13 January 1926, is from the National Photo Company Collection, consisting mostly of photographs taken in Washington DC, USA

EDITORS COMMENTS
This photograph captures a significant moment in the history of scientific research. Taken on January 13,1926, it showcases researchers from the United States Department of Agriculture conducting ultraviolet (UV) light therapy on white rats. The image is part of the National Photo Company Collection, predominantly featuring photographs taken in Washington DC. During this era, UV rays were still being explored and understood. Known for causing sunburns when exposed to sunlight, scientists were beginning to uncover their potential benefits in treating various skin conditions through phototherapy. This groundbreaking experiment sheds light on early attempts to harness the power of UV radiation for medical purposes. The picture reveals an intimate laboratory setting where an adult male researcher carefully administers UV light treatment using a specialized lamp while observing its effects on these small creatures. Ethical considerations surrounding animal experiments are evident as well, highlighting the ongoing debate between scientific advancement and ethical responsibility. As we gaze upon this snapshot frozen in time, we witness not only a pivotal moment in dermatology but also glimpse into the dedicated efforts made by biologists and medical researchers during that period. It serves as a reminder of our relentless pursuit to understand nature's mysteries and improve human lives through scientific exploration.
