Captain Stephen Olop (1879-1974) worked as a federal agent under Indian Services as superintendent of construction for Native American Indian Schools. He is documented at the Rosebud Indian School (1913-14) and the Ute Navajo Springs Agency (1915-16). He later served in the U.S. Army during World War I. He loaned a large number of American Indian objects to History Colorado. Accession records indicate some objects were received for a loan in 1915, 1918, others in 1924. In 1949, he gifted 30 objects to History Colorado. The remainder was later converted in 1958 after multiple attempts to reach him. In 1965, he formally gifted the remainder, although in 1969 Olop requested some financial compensation. Payment of $1500 was made to him. He collected items from reservations and purchased others from young military officers who fought in conflicts often referred to as the “Indian Wars”.
