The history of codes of ethics in health care has almost exclusively been told as a story of how medical doctors developed their own professional principles of conduct. Yet telling the history of medical ethics solely from the physicians' perspective neglects not only the numerous allied health care workers who developed their own codes of ethics in tandem with the medical profession, but also the role that gender played in the writing of such professional creeds. By focusing on the predominantly female organization of the American Physiotherapy Association (APA) and its 1935 "Code of Ethics and Discipline," I demonstrate how these women used their creed to at once curry favor from and challenge the authority of the medical profession. Through their Code, APA therapists engaged in a dynamic dialogue with the male physicians of the American Medical Association (AMA) in the name of professional survival. I conclude that, contrary to historians and philosophers who contend that professional women have historically operated under a gender-specific ethic of care, the physiotherapists avoided rhetoric construed as feminine and instead created a "business-like" creed in which they spoke solely about their relationship with physicians and remained silent on the matter of patient care.
