Went's father was the prominent Dutch botanist F.A.F.C. Went. After graduating from the University of Utrecht, Holland in 1927 with a dissertation on the effects of the plant hormone auxin, Went then worked as a plant pathologist in the research labs of the Royal Botanical Garden in Buitenzorg, Dutch East Indies (now Bogor, Indonesia) from 1927 to 1933. He then took a position at Caltech in Pasadena, California, first researching plant hormones. His interest gradually shifted to environmental influences on plant growth. At Caltech he was among the first to demonstrate the importance of hormones in plant growth and development. He played an important role in the development of synthetic plant hormones, which then became the basis of much of the agricultural chemical industry. Frees is known for the Cholodny-Went model, named after Went and the Soviet scientist N. Cholodny. They proposed it in 1937, after coming independently to the same conclusions.[1] This is an early model describing the phototropic and gravitropic properties of emerging shoots of monocotyledons. It proposes that auxin, a plant growth hormone, is synthesized in the coleoptile tip, which senses light or gravity and will send the auxin down the appropriate side of the shoot. This causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface.[2] Funded by generous donors, Went constructed a series of greenhouses at Caltech in which he could vary light conditions, humidity, temperature, air quality and other variables. In 1949 this led to him to construct a large new complex of climate-controlled rooms called the Earhart Plant Research Laboratory, also known as the "phytotron."[3] Here he produced foundational research of the effects of air pollution on plant growth. In 1958 Went was appointed director of the Missouri Botanical Garden and professor of Botany at Washington University in St Louis, at a point where he had become a world recognized authority on plant growth. He moved from Pasadena to St. Louis with his wife Catharina and their two children, Hans and Anneka. After the opening of the Climatron, the worlld's first geodesic dome greenhouse, Went’s vision of a renewed Missouri Botanical Garden eventually came into conflict with that of its Board of Trustees, and he resigned as director in 1963. After two years as simply Professor of Botany at Washington University, in 1965 he then became director of the Desert Research Institute at the University of Nevada-Reno, where he continued his research on desert plants for the remainder of his career, and on occasion lectured in the Department of Biology, University of Nevada-Reno. He remained active in many fields of botany until his death in 1990. {{Botanist|F.W.Went|Went}}References1. ^{{cite journal| journal=Plant Physiology | title=Basipetal Auxin Transport Is Required for Gravitropism in Roots of Arabidopsis | author=Rashotte|date=February 2000 | volume=122 | number=2| pages=481–490 | doi=10.1104/pp.122.2.481|display-authors=etal| pmc=58885}} 2. ^{{cite web | title=Phototropism - Cholodny-went Theory| publisher=JRank | accessdate=2012-05-29 | url=http://science.jrank.org/pages/5198/Phototropism-Cholodny-Went-theory.html}} 3. ^{{cite book|last1=Munns|first1=Jakub|title=Engineering the Environment: Phytotrons and the Quest for Climate Control in the Cold War|date=2017|publisher=University of Pittsburgh|pages=35}} External links
