AbstractProfessor Liley's most notable contribution to medicine was the introduction of intrauterine fetal blood transfusion in the management of Rh sensitization. His work has had worldwide recognition. He is Research Professor in Perinatal Physiology, Postgraduate School of Obstetrics and Gynecology, University of Auckland. It would be illogical for the founder of fetology to accept the thesis that his intrauterine patients had no right to life. Dr. Liley is the first president of the Society for the Protection of the Unborn Child. Not a Catholic, his leadership is particularly effective in a pluralistic society that sometimes regards abortion as merely a "Catholic issue."
