Charles Stewart Parker

Charles Stewart Parker (1882-1950) was an American botanist.

He was the head of the department of botany at Howard University in Washington, D.C. He had discovered and described 39 species of plants and had authored 60 papers.

During 1923-24, he served as a plant pathologist for the western district of North Carolina as a "dollar a year man" under appointment of the U.S. Bureau of Plant Industry. (Dollar a year men were business and government executives who helped the government mobilize and manage American industry during periods of war, especially World War I, World War II, and the Korean War. U.S. law forbids the government from accepting the services of unpaid volunteers.)

Parker worked out the life history and control of a blight of stone fruits, which according to record, had cost the grows in Washington state $250,000 in loss to cherries alone.
