wards. They wanted to show other attendants alternatives to violence when dealing with patients. Frank Olmstead, chairman of the War Resisters League observed: Outraged workers surveyed CPS men in other hospitals and learned of the degree of abuse throughout the psychiatric care system. Contacting church managers and government officials, the COs begin advocating for reforms to end the abuses. Conditions were exposed in institutions such as Cleveland State Hospital, Eastern State Hospital in Virginia and Hudson River State Hospital. One explained: The reformers were especially active at the Byberry Hospital in Philadelphia where four Friends initiated The Attendant magazine as a way to communicate ideas and promote reform. This periodical later became The Psychiatric Aide, a professional journal for mental health workers. On May 6, 1946 Life Magazine printed an exposé of the mental healthcare system based on the reports of COs. Another effort of CPS, Mental Hygiene Project became the National Mental Health Foundation. Initially skeptical about the value of Civilian Public Service, Eleanor Roosevelt, impressed by the changes introduced by COs in the mental health system, became a sponsor of the National Mental Health Foundation and actively inspired other prominent citizens including Owen J. Roberts, Pearl Buck and Harry Emerson Fosdick to join her in advancing the organization's objectives of reform and humane treatment of patients. Medical experiments A faction of the Civilian Public Service camps developed into a scientific research unit known as Camp #115, or the “Guinea pig units.” These units included around 500 conscientious objectors who volunteered to be scientific test subjects in a wide range of human medical experiments in the country’s top universities and hospitals. The majority of these experiments were conducted under the direction and approval of the Office of Scientific Research and Development (OSRD), the Committee on Medical Research (CMR), and the Surgeon General at leading academic and medical institutions such as Harvard Medical School, Yale and Stanford Universities, and Massachusetts General Hospital. These experiments involved a range of research topics, including studying disease, survival in extreme conditions, and equipment testing. The experiments often endangered the health of the COs. The following chart lists the unit numbers, facility, type of project, capacity of CPS assignees, and dates of many experiments done on COs that were approved by the OSRD and CMR as reported by Selective Service. The numbers reported may be slightly inaccurate as some COs and experiments were not properly
