Dilworth Wayne Woolley (July 20, 1914 – July 23, 1966) was a Canadian-born American biochemist, who did important work on vitamin deficiency, and was one of the first to study the role of serotonin in brain chemistry.
Dilworth Wayne Woolley was born in 1914, in Raymond, Alberta, the son of Americans living in Canada. His extended family were prominent members of The Church of Jesus Christ of Latter-day Saints; his great-grandfather was Edwin Dilworth Woolley, a Mormon bishop in Utah.
Wayne Woolley (as he was known) was a precocious child who finished high school at age 13, and completed an undergraduate degree in chemistry at the University of Alberta at age 19. He pursued graduate studies in the department of agricultural chemistry at the University of Wisconsin, where he earned his PhD in 1939. His graduate research with Conrad Elvehjem concerned nicotinic acid as a treatment for canine blacktongue, with implications for human pellagra.
Woolley spent much of his career at the Rockefeller Institute for Medical Research in New York City. His major work focused on serotonin in brain chemistry: how substances such as LSD might affect the action of serotonin, how disorders of serotonin function might be responsible for mental disorders, and how serotonin might play a part in memory and learning. Though his career was shorter-lived than expected, subsequent work by others has developed many of Woolley's hypotheses in productive directions. One of his assistants, Robert Bruce Merrifield, won the Nobel Prize in Chemistry in 1984, for work on peptide synthesis they did together in the 1950s.
