Arthur B. Gahan, 1905-1961

This series consists primarily of a nearly complete set of publications by Arthur B. Gahan in the field of entomology. In his early career, Gahan wrote on a wide variety of entomological topics, including mosquitoes, greenhouse pests of Maryland, and the aphidinae of North America. Gahan published in various outlets, including the Bulletin of the Maryland Agricultural Experiment Station, the Canadian Entomologist, and in several conference proceedings. As Gahan's work grew more specialized, he focused on Chalcidoidea, one of the largest groups of parasitoid wasps. Gahan kept a detailed, numbered inventory of his 120 publications on index cards; the following publications are missing from the series: 1-3, 5-7, 9-11, 16-18, 28, 32, 34, 52, 57, 58, 62, 67, 72, 85, 86, and 99. Also included in this series are detailed employment records for Gahan, dating from his initial 1913 appointment as an Entomological Assistant in the Bureau of Entomology, U. S. Department of Agriculture, to his retirement in 1951 from the Bureau of Entomology and Plant Quarantine.
