George Wald was an American scientist whose groundbreaking research illuminated the biochemical processes of human vision. He investigated the pigments within the retina, particularly rhodopsin, and his discoveries that vitamin A is a key component of the retina and that rhodopsin interacts with light revolutionized our understanding of how the eye detects color and light. His work synthesized chemistry, biology, and physics to explain how light triggers visual signals in the eye. Wald's persistence in scientific inquiry and his dedication to uncovering the fundamental mechanisms of vision left an indelible mark on the fields of physiology and medicine.
