Dr. Farrington Daniels Jr. (1918-2002) devoted his career to interdisciplinary research and education in medicine, physiology, and environmental science. The son of University of Wisconsin chemistry professor Farrington Daniels (1889-1972), he was raised in Madison and graduated from the University of Wisconsin in 1940. He began medical studies, while earning a master's in zoology in 1942, and then transferred to Harvard Medical School where in December 1943 he graduated with the accelerated wartime medical class of 1943B. After serving an internship at The New York Hospital, Daniels was commissioned first lieutenant in the U. S. Army Medical Corps in the Neurosurgery Service. He left the Army as captain in 1947. At The New York Hospital - Cornell University Medical College from 1947-1949, he served his medical residency. At the Harvard University School of Public Health, Daniels received a master's in public health in 1952. His environmental physiology research for the U. S. Army Quartermaster began in 1950 and ended in 1955. His research on heat and cold stress during the Korean War contributed to the design of military clothing and equipment. Daniels taught dermatology at the University of Oregon (1955-1961), was appointed associate professor of dermatology at University of Illinois Medical School (1961), and became head of the Dermatology Division at Cornell University Medical College (1962-1984). While at Cornell, Daniels was attending physician and head of dermatology at The New York Hospital (1962-1981). Following retirement to Madison in 1984, the University of Wisconsin Medical School appointed him visiting emeritus professor. During his career, he authored or coauthored more than 100 published scientific articles. His research on the impact of ultraviolet radiation on skin began in the late 1950s and helped develop the links between UV radiation, sunburn, and skin cancer. This led to research on the evolution of human skin color and assessments on the impacts of increased UV radiation stemming from pollution or nuclear weapons' use. In addition to pursuit of science, he was an avid photographer and a student of history.
