Van Rensselaer Potter is usually credited with coining the term bioethics and with founding this field. However, the rediscovery of the article “Bioethics: A Panorama of the Human Being’s Ethical Relations with Animals and Plants,” published in 1927 by Fritz Jahr in the German magazine Kosmos, necessitates a revision of this history of the foundation of bioethics. While Potter made significant contributions to this field, the importance of Jahr to the founding of bioethics should be recognized.
