Career

Together with Warburg, Wald identified the presence of vitamin A in the retina. Meanwhile, vitamin A then had just been isolated by scientist, Paul Karrer, in Zurich, Switzerland. Wald travelled to Zurich to complete the identification at Karrer’s laboratory.

Career

George Wald is known for his work on the physiology of the eye. His studies showed how vitamin A improved vision and how cells in the retina perceived colours and passed images to the brain. Through his experiments he discovered that Vitamin A was a component of the retina. It was yielded when the pigment rhodopsin was exposed to light along with protein opsin. As such, he proved that vitamin A was essential in retinal function.
