The papers consist of correspondence, professional files, research materials, writings, personal papers, and printed matter documenting Isidore Falk's career as an advocate of national health insurance and other programs related to public health. Of particular significance are the materials from his years with the Social Security Board (1936-1954), which document the campaign for government supported health insurance in the United States. Falk conducted public health and medical care surveys for the World Bank in Malaya, Singapore, Panama and the Canal Zone, and also prepared a survey of Union health programs (1958-1960) for the United Steelworkers of America. He founded the Community Health Care Center Plan in New Haven and the files record his activities as director (1970-1979). His active participation in professional organizations is reflected in correspondence and other papers. These papers form part of the Contemporary Medical Care and Health Policy Collection.
