Du début des années 1930 à sa retraite, en 1977, il a été la figure dominante dans le domaine de la  biochimie des  photopigments  rétiniens, et le prix Nobel de physiologie, qu'il partagea en 1967 avec les neurophysiologistes H. K. Hartline et R. Granit, n'avait fait qu'entériner une réputation solidement établie. Né à New York le 16 novembre 1906 il y fait toutes ses études, et c'est à l'université Columbia qu'il est initié par Selig Hecht à la  physiologie de la  vision. Hecht était, dira Wald, « l'un des grands mesureurs de la vision humaine », mais la mesure psychophysique n'était pour lui qu'un moyen de progresser vers l'élucidation des mécanismes moléculaires sous-jacents.

His further experiments showed that when the pigment rhodopsin was exposed to light, it yielded the protein opsin and a compound containing vitamin A. This suggested that vitamin A was essential in retinal function. In the 1950s, Wald and his colleagues used chemical methods to extract pigments from the retina. Then, using a

Abstract Vitamin A and retinene, the carotenoid precursors of rhodopsin, occur in a variety of molecular shapes, cis-trans isomers of one another. For the synthesis of rhodopsin a specific cis isomer of vitamin A is needed. Ordinary crystalline vitamin A, as also the commercial synthetic product, both primarily all-trans, are ineffective. The main site of isomer specificity is the coupling of retinene with opsin. It is this reaction that requires a specific cis isomer of retinene. The oxidation of vitamin A to retinene by the alcohol dehydrogenase-cozymase system displays only a low degree of isomer specificity. Five isomers of retinene have been isolated in crystalline condition: all-trans; three apparently mono-cis forms, neoretinenes a and b and isoretinene a ; and one apparently di-cis isomer, isoretinene

Wald, George US biochemist who explored the chemistry of vision. He discovered the role played in night vision by the retinal pigment rhodopsin, and later identified the three primary-colour pigments. Nobel Prize for Physiology or Medicine 1967. Wald was born and educated in New York. He spent his academic career at Harvard from 1935, becoming professor of biology 1948. In the 1970s he spoke out against the US role in the Vietnam War. Studying rhodopsin, which occurs in the rods (dim-light receptors) of the retina, Wald discovered in 1933 that this substance consists of the colourless protein opsin in combination with retinal, a yellow carotenoid compound that is the aldehyde of vitamin A. Rhodopsin molecules are split into these two compounds when they are struck by light, and the enzyme alcohol dehydrogenase then further reduces the retinal to form vitamin A. In the dark the process is reversed, but over a period of time some of the retinal is lost. This deficiency has to be made up from vitamin A, and if the body's stores are inadequate, night blindness results. In the 1950s Wald found the retinal pigments that detect red and yellow-green light, and a few years later the pigment for blue light. All these are related to vitamin A, and in the 1960s he demonstrated that the absence of one or more of them results in colour blindness.

After attending public primary and secondary I schools in Brooklyn, he received the degree of Bachelor of Science from Washington Square College of New York University in 1927; and then took graduate work in zoology at Columbia University, from which he received the Ph.D. in 1932.
