Harold Macy papers

Identifier: ua-00273

Scope and Content

The Harold Macy papers consist of correspondence, reports, talks and writings and historical materials generated during Macy’s college years as a student at Cornell University through his years of service to the University of Minnesota as professor, agricultural experiment station director and dean of the Institute of Agriculture. The collection is composed primarily of professional correspondence and talks that Macy gave based on his research interests, principally the use of technology in mold prevention in dairy products.

The collection is arranged in four series:

Series 1, Associations, Organizations and Committees, contains correspondence, reports, questionnaires, meeting minutes and conference materials from national, regional and state agricultural and scientific organizations Macy was involved with, as well as selected University of Minnesota committees and boards.

Series 2, Correspondence, contains primarily personal correspondence, the bulk of which covers the late 1940s to the mid 1960s.

Series 3, Subject Files, includes Macy family biographical information, correspondence concerning awards and honors bestowed on Macy during his career, many of his college and graduate school notebooks, and family photographs.

Series 4, Talks and Writings, are primarily typescripts of technical and professional papers that Macy wrote about dairying concerns, including mold prevention and spoilage in milk, butter and cream, and dairy animal health. Often the papers formed the basis of talks Macy gave to commercial farm and dairying groups. Most of the writings date from the late 1920s when Macy taught dairy bacteriology in the department of animal husbandry. Two folders of collected talks cover Macy service to the University as assistant director and director of the agricultural experiment station on the St Paul campus.

He served as a bacteriologist and chief sanitary inspector for the American Red Cross from 1917-1918, and studied and worked at the Yale Army laboratory school. During WWII, Macy served with the Army Sanitary Corp in France. He was awarded the Chevalier of the French Legion of Honor and the Order of Public Health from the French government for his work helping to control epidemics in human populations and delivering sanitation supplies to medical outposts during the closing months of the war.

Macy came to the University of Minnesota in 1918 as assistant professor of dairy bacteriology, being promoted to professor in 1935. While at the University, his research on mycology and bacteriology helped improve the quality of Minnesota dairy products. He also taught short courses to producers and published over 150 technical bulletins based on his work. As dean of the Institute of Agriculture, he oversaw the administrative transition of the department of Agriculture to the Institute of Agriculture and the broadening of the Institute’s activities to include international collaborations in the field and classrooms.
