However, rupture of the uterine scar with subsequent labor was appreciated early. This danger resulted in the oft-quoted remark by Cragin (1916) that “Once a cesarean, always a cesarean.” During the intervening 50 years, enthusiasm developed to allow many of these women to be delivered vaginally. But, as chronicled next, this support has waned during the past three decades. So, as we reach the 100-year mark of Cragin’s pronouncement, the issue remains largely unsettled.
