About C. Everett Koop
Charles Everett Koop was an American pediatric surgeon and public health administrator who served as the 13th surgeon general of the United States under President Ronald Reagan from 1982 to 1989. According to the Associated Press, "Koop was the only surgeon general to become a household name" due to his frequent public presence around the HIV/AIDS crisis of the 1980s. Koop was able to establish the nation's first neonatal surgical intensive care unit there in 1956. In 1937, he earned his Bachelor of Arts in zoology degree from Dartmouth College, where he was given the nickname "Chick" (occasionally used for his first name, Charles, but here an allusion to a chicken coop). He invented anesthetic and surgical techniques for small bodies and metabolisms and participated in the separation of several sets of conjoined twins whose condition other physicians at the time considered hopeless. Koop became a professor of pediatric surgery in 1959 and professor of pediatrics in 1971 at the University of Pennsylvania School of Medicine.
