There, he and Frits Went codiscovered natural auxin, a hormone regulating both growth and its selective inhibition in plants; Thimann also demonstrated auxin-like functions in certain synthetic substances. At Harvard (1935–65), he investigated the physiology of bacteria, fungi, protozoa, and forest trees.
