Kenneth V. Thimann Papers, MS 71, Special Collections and Archives, University Library, University of California, Santa Cruz.
Gift of the Thimann family in 1997.
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.
Thimann was born in Ashford, England, on August 5, 1904. He earned his B.Sc. and Ph.D. in chemistry and biochemistry from
Imperial College, University of London, and a diploma from the University of Graz, Austria. He taught at the University of
London for several years before coming to the California Institute of Technology in 1930 as an instructor in bacteriology
Thimann joined the faculty of Harvard University in 1935 and remained there for 30 years. He was director of Harvard's Biological
Laboratories from 1946 through 1950 and was Higgins Professor of Biology from 1962 to 1965. He was an associate at Eliot House,
and in 1962 he became the first master of East House at Radcliffe College when Radcliffe organized its women's residences
along the lines of the Harvard houses.
During World War II Thimann was a technical consultant to the U.S. Navy. He worked with the Navy's operations research group
in Washington, D.C., London, and Pearl Harbor.
In 1965 Thimann moved west at the urging of UCSC's founding chancellor, Dean McHenry, to become professor of biology and the
first provost of Crown College, the third of UCSC's eight academic colleges. Thimann retired as provost in 1972 but remained
active in research and university affairs for many years. He moved to Haverford in 1989, where he set up an active research
collaboration at the University of Pennsylvania with the eldest of his three daughters.
Among Thimann's most noteworthy contributions to the campus was his nurturing of the UCSC Arboretum into an internationally
known collection of plants from Australia, New Zealand, and South Africa. He chaired the chancellor's committee on Arboretum
and plantations for 15 years and helped to launch the Arboretum Associates, a community support group, in 1977. He also was
an accomplished amateur pianist and founded the Crown Chamber Players with his wife, Ann Mary Bateman Thimann, a skilled weaver
who died in 1987.
