Despite an august history of 150 years, sedimentology as a science has advanced most rapidly since about 1950. This rapid advance resulted from a change of sedimentology as a pure to an applied science. Economic incentives, particularly in the exploration for petroleum, spurred prodigious expansion and rapid advances in sedimentology. Major oil companies began to realize that sedimentology was the key to success in exploration. Recognition of the enormous value of sedimentology as a key to the discovery of stratigraphic traps represented a turning point in the history of the science. The 1947 report of the Research Committee of the American Association of the Petroleum Geologists, under the leadership of Shepard W. Lowman, Rensselaer Polytechnic Institute, stated that research in sedimentology is the most-urgent need in petroleum geology. Processresponse models and facies analysis dominated sedimentology. Convulsive and catastrophic events as sedimentological processes gained acceptance. This paper concludes with the mid-1980s after which sequence stratigraphy revolutionized the study of sedimentary deposits. This account is a personal perspective related through personal involvement in scientiﬁc societies, technical journals, and research.
