The International Society Daughters of Utah Pioneers (ISDUP, DUP) was organized 11 April 1901 by Annie Taylor Hyde. The ISDUP was organized for historical, educational and public purposes and is completely non-political and non-sectarian. It is dedicated to perpetuating the names and achievements of those men, women, and children who journeyed to the State of Deseret/Utah Territory. The organization encompasses a broad scope of services, ranging from the preservation of historic landmarks to the education of thousands of school children and other citizens about their pioneer forebears. The organization also maintains the Pioneer Memorial Museum (DUP Museum) located in Salt Lake City, Utah. The Museum houses the world's largest collection of artifacts on one particular subject and features displays and collections of memorabilia from the time the earliest settlers entered the Valley of the Great Salt Lake until the joining of the railroads at a location known as Promontory Point, Utah, on May 10, 1869.
