University of Colorado Health Sciences Center

The University of Colorado Health Sciences Center conducted a series of non-reported, unpublished blood-cell studies between 1960 and 1968 on male prisoners from the Colorado State Penitentiary in Cañon City and local county jails in the Denver area. The principal investigator had served as a Manhattan Project physician at Billings Hospital in Chicago and was closely affiliated with the Atomic Energy Commission during his career. The central goal of these studies was to determine red-blood cell regeneration, survival rates, and characteristics after conditions of excessive blood loss and severe iron deficiency. The University of Colorado administration took extra precautions to ensure that these studies were not publicized for concerns over ethical and human rights code violations.
