The study of bioethics in Argentina owes much to the efforts of José Alberto Mainetti, who in 1972 founded the Institute of Medical Humanities, devoted to researching, teaching, and publicizing the discipline. Because of growing interest in the field of bioethics, a Bioethics Center was created in the Institute in 1987 and it has stimulated the organization of several groups in various provinces in the country. One of the most important of them, located at the National University of Mar del Plata, is responsible for designing a graduate-level specialization in bioethics and for organizing the First Mar del Plata Bioethics Workshop. This interdisciplinary group examines the bioethical implications of concrete scientific and professional activities as well as legislative measures and decisions affecting the public.
