- In this June 25, 1945 picture, an army doctor watches as malaria-carrying mosquitoes bite the stomach of inmate Richard Knickerbockers, serving 10 to 14 years, in the malaria ward at Stateville Penitentiary in Crest Hill, Ill. Around the time of World War II, prisoners were enlisted to help the war effort by participating in studies that could help the troops. A series of malaria studies at Stateville Penitentiary in Illinois and two other penitentiaries were designed to test antimalarial drugs that could help soldiers fighting in the Pacific. Shocking as it may seem, government doctors once thought it was fine to experiment on disabled people and prison inmates.
