Definition
Gerald E. McClearn (1927 – 2017) was an American psychologist and behavioral geneticist noted for his pioneering research on the genetic and environmental influences on learning, memory, and the aging process.
Overview
Born in 1927, McClearn earned his Ph.D. in psychology and pursued an academic career that included appointments at the University of Southern California and the University of Colorado Boulder. At Colorado, he served as the founding director of the Institute for Behavioral Genetics (IBG), a leading center for research on the hereditary basis of behavior. Throughout his career, McClearn authored numerous influential studies and books, including works on the genetics of cognition, the role of stress hormones in behavior, and the biological underpinnings of aging. He was a past president of the Behavioral Genetics Association and was elected to the National Academy of Sciences in recognition of his contributions to the field.
Etymology/Origin
The surname “McClearn” is of Irish origin, derived from the Gaelic “Mac Giolla Chríon,” meaning “son of the devotee of St. Crian.” The given name “Gerald” comes from the Germanic elements ger (“spear”) and wald (“rule”).
