Stanley George Stephens

Stanley George Stephens (September 2, 1911 – November 7, 1986) was a British-American plant geneticist known for his work on cotton genetics, crop domestication, and the evolution of Gossypium. He was elected to the National Academy of Sciences in 1967.

Early life and education Stephens was born in Worcestershire, England. He studied at St John's College, Cambridge, where he received a degree in natural sciences in 1933 and a diploma in agricultural science in 1934. He later earned a Ph.D. from the University of Edinburgh in 1941 with a dissertation on yield characters in cereals, particularly oats.

Career and research In 1938, while still a doctoral student, Stephens became an assistant geneticist at the Cotton Research Station in Trinidad, where he began research on the genetics, cytogenetics, and evolution of cotton. He also studied archaeological cotton remains from coastal Peru as evidence bearing on the early domestication of Gossypium barbadense.

Among his doctoral students at North Carolina State was maize geneticist Major M. Goodman.

Stephens coauthored The Evolution of Gossypium and the Differentiation of the Cultivated Cottons, published by Oxford University Press in 1947.

Honors Stephens was appointed a William Neal Reynolds Professor at North Carolina State University in 1951. He received the Cotton Genetics Award in 1962, was elected to the National Academy of Sciences in 1967, received the North Carolina Award in 1968, and received the Oliver Max Gardner Award from NCSU in 1970.
