Dr. John Charles Cutler
U.S. Public Health Service Physician and Serial Human Experimenter
Lead researcher who directed the Guatemala syphilis experiments, participated in the Tuskegee syphilis study, and conducted the Terre Haute prison experiments
Overview
John Charles Cutler (1915-2003) was a United States Public Health Service physician who directed some of the most egregious human experimentation programs in American history. From 1946 to 1948, Cutler led the Guatemala syphilis experiments in which U.S. government researchers deliberately infected at least 1,308 Guatemalan soldiers, prisoners, psychiatric patients, and sex workers with syphilis, gonorrhea, and chancroid without their knowledge or consent; at least 83 subjects died. Cutler had previously conducted similar experiments at Terre Haute federal prison in Indiana in 1943-1944, deliberately infecting inmates with gonorrhea. He later served as an advisor to the Tuskegee syphilis study, in which treatment was withheld from 399 Black men with syphilis for 40 years. Cutler remained unapologetic throughout his life, defending both the Guatemala and Tuskegee experiments in interviews. He rose to become Assistant Surgeon General of the United States and a professor at the University of Pittsburgh, suffering no legal consequences for his actions. His Guatemala experiments were only discovered in 2010 when historian Susan Reverby found his archived papers.
