This is a 1953 portrait of Dr. William “Bill” Collins, a research biologist with what had been the National Center for Infectious Diseases (NCID), Division of Parasitic Diseases (DPD). This photograph was taken of Dr. Collins while he was a member of the U.S. Army during the Korean War (1950 – 1953). 2004 marked the 50th anniversary of Dr. Collins’s service as a federal employee. Beginning October 1, 1954, Dr. Collins was a part of the U.S. Army Chemical Corps. He has developed the vast majority of the nonhuman primate animal model systems used to study the immunobiology of human and nonhuman primate malaria. He was the lead investigator responsible for the establishment of the CDC, as a major international center for its work on malarial vaccines.
