Charles Albert Shull

Charles Albert Shull (1879–1962) was an American botanist and plant physiologist who played a central role in establishing plant physiology as a professional discipline in the United States. He was professor of plant physiology in the Department of Botany at the University of Chicago from 1921 to 1944. Shull was the founding president of the American Society of Plant Physiologists in 1924 and the founding editor-in-chief of the society's journal, Plant Physiology, serving from 1925 to 1945. Under his editorial leadership the journal became a major international venue for research in plant physiology and helped shape the development of the field during the early twentieth century. He was one of several siblings who became prominent scientists; his brothers included the geneticist George Harrison Shull, the zoologist Aaron Franklin Shull, and the botanist and botanical illustrator J. Marion Shull.
