Collections: Plant Pathology

The plant pathologist Walter M. Banfield joined the faculty at UMass Amherst in 1949 after service in the Army Medical Corps during World War II. A native of New Jersey with a doctorate from the University of Wisconsin, Banfield’s research centered on diseases affecting shade trees in the United States, and he is widely credited with identifying the origin of Dutch elm disease. As early as 1950, he emerged as a prominent advocate for the protection of open space and farmland, becoming a founder of the Metacomet-Monadnock Trail. An avid hiker and canoeist, he remained in Amherst following his retirement. He died at age 95.

The Banfield Papers include records from his Army service, family records, and professional and family correspondence – particularly between Banfield and his wife Hertha whom he met in Germany during WWII. The professional correspondence documents Banfield’s commitment to land preservation, and include many applications for land to be set aside for agricultural or horticultural use. Banfield was also a talented landscape photographer, and the collection includes a large number of 35mm slides reflecting his varied interests, including images of Europe at the end of World War II and various images of landscape, trees, forests, and other natural features that he used in teaching.

Shortly after earning his doctorate in plant pathology from Cornell in 1954, the internationally known phytopathologist, Francis W. Holmes began his career at UMass Amherst. Working in the Department of Plant Pathology (1954-1991) and later as Director of the Shade Tree Laboratories, Holmes became a leader in the study of Dutch elm disease, and he conducted important research on injury to trees from road salt and the relationship between salt injury and Verticillium wilt disease. During Holmes’s tenure, the Shade Tree Labs tested nearly 250,000 elm samples for Dutch elm disease and diagnosed a great variety of other diseases on more than 150 other types of trees. While on a Fulbright fellowship in the Netherlands, he devoted his free time to preparing a monograph on six Dutch women scientists who discovered the source of Dutch elm disease in the 1920s and 1930s. Holmes retired from the University in 1991 and remained in Amherst until his death in 2007.

The papers document Holmes’s research on shade trees and his tenure as a professor of microbiology. The collection includes some professional correspondence (1954-1977), awards, research notes and publications, and memorabilia. Holmes’s translations of phytopathological works from Dutch to English may be of interest to scholars of Dutch elm disease.
