This collection contains correspondence, field notebooks, and research files.
Kenneth V. Thimann was a pioneering researcher in the field of plant physiology. He was best known for describing the functions of hormones in the control and development of plants. In particular, he identified the growth hormone known as auxin and characterized its chemical structure, a discovery of critical importance to the agriculture and horticulture industries. He also was highly regarded for his research on 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 in life, he began to focus on the factors controlling the mechanisms of plant senescence, especially the aging of leaves.
