John Hunter Thomas

John Hunter Thomas (March 26, 1928 – July 20, 1999) was an American botanist, professor of biological sciences at Stanford University, curator and director of the Dudley Herbarium, and joint curator at the California Academy of Sciences. He was known for his study of plants in the Sonoran Desert, the Santa Cruz Mountains, and the Alaska North Slope, and for his history of botanical exploration in Washington, Oregon, and California. His doctoral research on the plants of the Santa Cruz Mountains was published as a guide to the vascular plants of coastal, central California, and was recognized as a standard reference work for regional flora. It was used for decades as teaching material for courses in systematic botany and the ecology of vascular plants at Stanford. Thomas helped establish the Jasper Ridge Biological Preserve and was a primary contributor to what later became the Jasper Ridge Oakmead Herbarium (JROH). In total, Thomas collected more than 20,000 plant specimens for herbaria throughout his career.

Biography

Thomas was born in Beuthen, Germany, David T. Powers and Associates, Inc. 1991. on March 26, 1928, to American parents Roy, a mining engineer, and Lucile Thomas. ''San Francisco Chronicle'' 1967, p. 29. He had a younger sister, Mary Louise Thomas. Thomas spent his early childhood in Poland. Ehrlich et al. 2000, p. 1. In 1939, his family moved back to the United States, taking up residence in New England. He graduated in 1945 from Kent School in Connecticut, and earned his bachelor's degree from the Caltech in 1949. Workman 1999.

After completing his undergraduate work at Caltech, Thomas spent the next decade as an intermittent graduate student at Stanford University (MA, 1949; PhD, 1959) broken up by active military service. Timby 1998, p. 14. His master's thesis focused on the taxonomy and distribution of the evening primrose family of flowering plants in the Sonoran Desert. In 1950, he made a preliminary identification of two species of Onagraceae. That same year, he joined Stanford botanist and faculty member Ira Loren Wiggins to study the plants in Point Barrow, Alaska. From 1951 to 1952, Thomas served as an officer in the United States Navy Reserve during the Korean War after being called to active duty. On October 7, 1951, he was wounded on the ''Gearing''-class destroyer USS ''Ernest G. Small'' during the attack on Hungnam, North Korea. The ship hit a mine, damaging the bow, killing 9, and wounding 18. Thomas survived, but for the rest of his life he carried shrapnel embedded in his body.

From 1956 to 1958, Thomas taught at Occidental College. With Wiggins as his advisor, Thomas completed his dissertation, informed by the plant collections of William Russel Dudley, on ''The vascular plants of the Santa Cruz Mountains of central California'' in 1958, with Stanford publishing it as a book in 1961. Timby 1998, p. 6. His 1958 dissertation became a standard reference work for regional flora. It would later be used for decades as teaching materials for advanced courses in systematic botany at Stanford. Wiggins, who became director of the Naval Arctic Research Laboratory in 1950, later co-authored ''A Flora of the Alaskan Arctic Slope'' (1962) with Thomas. Between 1965 and 1969, Thomas spent his summers as a visiting associate professor at the Flathead Lake Biological Station, a year-round, ecological research and education center run by the University of Montana. Ehrlich et al. 2000, p. 2; Museum of Natural History 1971, p. 4. From 1961 to 1969, Thomas lectured at Stanford, becoming associate professor from 1969 to 1977. He was made professor in 1977, staying there until his retirement as professor emeritus of biological sciences in 1995.

From 1961 to 1965, Thomas served as the associate editor of the ''American Fern Journal''. Museum of Natural History 1971, pp. 4-5. He was the president of the California Botanical Society from 1975 to 1976, and previously, editor of their journal ''Madroño'' from 1963 to 1972. Thomas participated as a delegate to the International Botanical Congress from 1964 to 1987. ''Palo Alto Weekly'' 1999. He was also a fellow of both the California Academy of Sciences and the Arctic Institute of North America. Thomas served on the Academic Council's Committee on Libraries and the Associates of the Stanford University Libraries, and was an editorial board member for the Stanford University Press.

Dudley Herbarium

After Frederick E. Terman became Stanford university provost in 1954, there was a strong push towards biomedicine and biochemistry, particularly in terms of the potential for new federal funding available to the university for cellular and molecular biology research. Terman's administrative focus on these government grants led to the elimination of the Division of Systematic Biology in June 1965. This loss of funding paved the way for the eventual transfer and merger of the 850,000-specimen Dudley Herbarium collection from Stanford to the CAS Herbarium collection of 600,000 specimens. Timby 1998, p. 2. Thomas became associate curator of the Dudley Herbarium in 1962. Soon after, curator Roxana Stinchfield Ferris retired, leaving Thomas as curator from 1963 to 1972, becoming director of the herbarium from 1972 until 1995. In 1969, Thomas began working as a part-time joint curator at the Academy. The planned move and transfer of the specimen collections from Stanford to the Academy was eventually completed in 1976. Overall, Thomas collected more than 20,000 plants throughout his career for the Dudley Herbarium, with specimens taken from Alaska, Baja California, California, and Montana. Duplicate specimens from this collection were also deposited with the California Academy of Sciences and the California Botanic Garden (RSA-POM, Herbarium of Rancho Santa Ana Botanic Garden and Pomona College). Daniel 2008, p. 258.

Jasper Ridge Biological Preserve

In 1973, Thomas helped establish the Jasper Ridge Biological Preserve at Stanford. Ray 1999. The preserve, located in Portola Valley, California, contains samples of approximately 10% of the vascular plants in the state. Rawlings 2013, p. 18. Before Thomas began collecting in the area, there was a lack of proper voucher specimens of vascular plants. To address this problem, between 1955 and 1998, Thomas collected approximately 2,000 samples from the preserve. In 1992, he helped create the foundations for what would become the Oakmead Herbarium by giving his collection to Jasper Ridge, which he envisioned becoming a teaching and reference collection. It was eventually established in 1996, one year after his retirement.

Unlike the former Dudley Herbarium, which documented plants from the entirety of California, the Oakmead Herbarium had a much narrower focus, documenting and storing plant specimens taken from just the area of Jasper Ridge since 1867. The herbarium is located at the Leslie Shao-ming Sun Field Station, which was built in 2002 at the preserve. Along with John Rawlings and Toni Corelli, Thomas was one of the primary contributors to the plant collections at Oakmead. The collection now hosts approximately 5,500 specimens. According to Oakmead, "Thomas was the most prolific collector of grasses in the Jasper Ridge area with 361 sheets...and the most prolific collector of graminoids in general with 453 sheets collected from 1955 to 1992".

His personal herbarium, which contained thousands of duplicate specimens, was destroyed by insects shortly before his death. In 2011, entomologists Daniel J. Bickel and Paul H. Arnaud Jr named a new long-legged fly species after Thomas ('' Medetera johnthomasi''). '' Medetera'' is a large genus of flies in the family Dolichopodidae. "This species is named in honor of John Thomas," they wrote in their paper announcing their discovery, "who was a great supporter of the Jasper Ridge Biological Preserve and student of its flora. The species was collected in the marshes of Searsville Lake in the Preserve."

Environmentalism

During the environmental crisis of the late 1960s and early 1970s, questions about sustainable population size became part of a public debate across the United States. Thomas participated in this discussion along with other biologists and ecologists. ''Nevada Daily Mail'' 1971, p. 7. He expressed concerns about the dangers of human overpopulation and its impact on the environment and advocated for human population planning as one way to address the problem. He gave various talks at symposia and conferences about this topic. One early talk, "The Immorality of Too Many People", was delivered at Mills College on November 15, 1969. That same week, he participated in the "Human Relationships in the Year 2000" symposium at Central Washington State College that brought together scientists, philosophers, religious leaders, and politicians. Along with a variety of speakers, Thomas discussed the potential threat of a growing human population, its contribution to pollution, and its role in the destruction of the environment. Thomas highlighted the activities of the oil industry in the Alaska North Slope, which he said could lead to the removal of vegetation cover which acts as an insulator, whose habitat loss could lead to the acceleration of melting permafrost. He gave another talk discussing "the interrelated problems of overpopulation and pollution" at Michigan State University on October 13, 1970, where it was recorded by WKAR Radio. In March 1971, he gave the talk "The Population Component of our Current Crisis" at the annual Ojai Valley School teachers' conference. ''Oxnard Press-Courier'' 1971, p. 10. He was quoted in April of that year as saying "When we can deal adequately with the people we have now, giving everyone enough food, housing, clothing, peace, love, purpose and opportunity to achieve and fulfill themselves, we can then talk about more people and larger populations—not before."

Personal life

Thomas married Susan Davidson Thomas on December 3, 1966. They had no children. Although he was of the Catholic faith, he openly criticized the anti-birth control position of the Church, particularly the position of Pope Paul VI found in the 1968 encyclical ''Humanae vitae'', which condemned "artificial" birth control. His hobbies included reading English novels by authors like C. P. Snow and Evelyn Waugh, as well as running a printing press, which he used to publish satirical reviews of work by his peers under the title ''Cardboard Carton Corpse and Cadaver Container Corporation''. He died in a Menlo Park nursing home from Alzheimer's disease on July 20, 1999. A memorial service was held a month later, on August 24, at Stanford Memorial Church.
