Claim to Fame:
Wald was an American biochemist who was awarded one third of the 1967 Nobel Prize in Medicine for discovering vitamin A is essential for vision and for research into the effectiveness of retina cells to absorb light. He also extracted the pigments from the retina and measured the light absorbance of each pigment. This allowed him to determine the range of color vision possible from rod and cone cells of the eye.
