Biographical History

Harry Ardell Allard (1880-1963) was a botanist with the United States Department of Agriculture (USDA) for 40 years, working on collections of lichens and flowering plants, tobacco varieties, and interests in ornithology and entomology. When he retired in 1946, he had more than 200 publications to his name. He attended University of North Carolina, Chapel Hill graduating in 1905. In 1906 he joined the USDA, eventually working with the Office of Tobacco Investigations. While in this office, he became one of the first to identify the effect of aphids on Tobacco plants. In 1920 while working on seed production for Maryland Mammoth Tobacco, Allard worked with Dr. W. W. Garner discovering photoperiodism, the ability of flowering plants to determine the time of the season to bloom and produce seed based on the amount of daily sunlight.
