Thomas W. Whitaker

Thomas Wallace Whitaker (August 13, 1904 – November 29, 1993) was an American botanist and horticulturist who spent most of his career working as a geneticist for the United States Department of Agriculture (USDA). He specialized in the study of economically important plants such as squashes, investigating their systematics and resistance to disease.

Early life and education Whitaker was born August 14, 1904, in Monrovia, California. He grew up on a farm and worked his way through college, graduating from University of California, Davis in 1927 with a bachelor of science degree. Continuing his education under a DuPont Fellowship, he graduated from the University of Virginia (UVA) with a master's degree in 1929 and PhD in 1931. Both of those degrees were in biology with concentrations in genetics and cytology. While at UVA, he spent summers at the Blandy Experimental Farm. He did postdoctoral work at Bussey Institution and Arnold Arboretum at Harvard University.

Career Whitaker served as an associate professor at the women-only Agnes Scott College in Decatur, Georgia, from 1934 to 1936. In 1936 he began working as a geneticist for the USDA and remained in that role until he retired in 1973. While with the USDA he lived in La Jolla, California, and worked in the nearby Imperial Valley Experiment Station near Brawley, California. Whitaker specialized in amaryllis, cantaloupes and other Cucurbita, and lettuce in the search for disease resistance and better taste, and he investigated plant systematics. Whitaker died on November 29, 1993, in La Jolla. Volume 3 of Horticultural Reviews (1981) is dedicated to Whitaker. After retiring from the USDA, he traveled internationally extensively, collecting over 1,300 seed samples, three-quarters of which were cucurbits. He published over 70 academic articles during his lifetime. His last two articles were published in 1986 and 1990. (Amaryllidaceae) Amaryllis belladonna L. subsp. quentiniana Traub & Whitaker Pl.

Whitaker was honored with an eponymous summer squash variety, Cucurbita pepo summer-squash zucchini variety (Whitaker). This variety is highly disease-resistant and is parthenocarpic, having no seeds.
