9 linear ft. ; William Sill was born in Las Vegas, Nevada, July 30, 1937. He learned to love geology as a child, worked hard, and graduated high school in 1955. He graduated from BYU in Geology in 1963, having taken some time out to serve his country in the Coast Guard and Army Reserves (1956-7). Sill also served an LDS mission to Argentina from 1958-1961. Three months later, he and Nelida, an acquaintance from his mission, were married; the couple have since been sealed in the temple and are the parents of four children. Prior to graduation from BYU, Sill was accepted into Harvard; upon his arrival in Washington, D.C., with a friend, he was able to take part in the Martin Luther King march and hear his famous speech "I Have A Dream" September 1963, and speculates that he and his friend were the only BYU students in attendance. While at Harvard, he participated in paleontology digs in Kenya, 1964-5, and 1967. Sill received his Ph.D. in 1969, and was granted a postdoctoral fellowship at Yale even before he graduated. Following that, he spent many years in Argentina (noncontinuous) doing research and teaching; he also established the 1st public museum of natural history at the newly created National University of San Juan, and was instrumental in passing the law designating Ischigualisto, Argentina, as a state park. He led several very successful expeditions, sponsored by the Earthwatch Foundation, between 1963-2000, and was awarded a medal of honor for his work in the region in 2001.
