“They just found a sword swallower dead. The police suspect it's an inside job.”
Kenneth Vivian ThimannDied 15 Jan 1997 at age 92 (born 5 Aug 1904).English-American plant physiologist, who pioneered in the field of plant physiology, especially hormones that control the development of plants. In particular, he identified auxin, a growth hormone, and revealed its chemical structure (very important to agriculture and horticulture industries). He also researched the biosynthesis of pigments responsible for the colors of flowers and fruits, and the action of various zones of the light spectrum on photosynthesis. Later he studied the factors controlling the mechanisms of plant senescence, especially the aging of leaves. |
