in which a "rights-based" approach provided the foundation of much social action. The initial "inspiration" for a "patient bill of rights" came from an advocacy organization, the National Welfare Rights Organization (NWRO). In 1970, the NWRO list of patients' rights was incorporated into the Joint Commission's accreditation standards for hospitals, and reprinted and distributed by the Boston Women's Health Book Collective—authors of Our Bodies, Ourselves—as part of their women's health education program. The preamble to the NWRO document became the basis for the Patient Bill of Rights adopted by the American Hospital Association in 1972. The field of health advocacy also has deeper roots in the voluntary organization sector of society, where the early health advocates were more typically advocating for a cause, not for an individual. These health advocates preceded hospital-based patient advocates and are part of a long history of American involvement in social organizations. They were activists in social movements and voluntary associations including civic organizations, women's associations and labor organizations, and in the early disease-specific non-profits like the American Cancer Society (founded as the American Society for the Control of Cancer in 1913) or the March of Dimes (founded as the National Foundation for Infantile Paralysis in 1938). In the early part of the 20th century these advocates came to their work through other professional routes, often as social workers, attorneys, public health nurses or doctors. They were the Progressive era "new women" of Hull House and the Children's Bureau, the American Association for Labor Legislation leaders of the movement in 1919 for national health insurance, the nurses who worked with Lillian Wald to advocate for indigent health care through Visiting Nurse Services (1893), or with the Maternity Center Association (1918) to advocate for maternal and infant care for poor immigrants. They obtained their professional education in other disciplines and then applied it to health. Health advocacy also has 20th century roots in community organizing around health hazards in the environment and in the workplace. The Love Canal Homeowners Association, for example, was founded in 1978 by Lois Gibbs and others concerned about the high rate of cancer and birth defects in the community. These grass roots advocates often begin with a concern about perceived "clusters" of disease. The Newtown Florist Club on the south side of Gainesville, Georgia was founded by women who pooled their money to buy wreaths for funerals in their community; in
