Frank Wallace Notestein (1902 - 1983) was the founding director of the Office of Population Research.  He was the first director of the Population Division of the United Nations between 1946 and 1948, and became president of the Population Council in 1959. In March 1983, the Frank W. Notestein Memorial Fund was established with the purpose of bringing distinguished outside speakers to OPR on a more regular basis.  The weekly Notestein seminars have become an integral part of the research and training program at OPR.  They provide a forum in which OPR faculty, students, and visiting scholars can become acquainted with current research projects. The seminar features demographers and social scientists from the US and around the world.  OPR students also present a seminar on their doctoral work in this series in order to receive suggestions on their research and to obtain experience in making public presentations.
