C. Rufus Rorem, (1894-1988) was a pioneer in the development of group medical insurance and pre-paid health care. At the time the concepts were radical, but in 1937 he became head of the American Hospital Association's committee on hospital services, which fostered the first prepaid hospitalization plans in New York and other cities, followed in the 1940's by doctors' group practice. This collection includes out of print and difficult to access primary and secondary sources on Rorem’s work, including his 1929 dissertation which presents his major, and still relevant writings on financial accounting theory and practice in a comprehensive, integrated context.
