This 1962 image, depicts an inspection team in the process of reviewing blueprints for the Centers for Disease Control (CDC) field station, located in Phoenix, Arizona. This happened to be their final review of these drawings. From left to right, members of the team included Dr. Tom D. Y. Chin, Dr. Melvin Goodwin, and Dr. Alexander Langmuir. Originally, the Phoenix field station specialized in the study of diarrhea and dysentery, concentrating on vector-borne diseases transmitted by flies, which included polio. The field station eventually became heavily involved in the study of hepatitis, as well.
