Captain Stephen Olop (1879-1974) was an Indian Agent for the Ute Mountain Utes in 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. In the accession file, records indicate some objects were received for a loan in 1915, 1918, others in 1924. In 1949, he gifted 30 objects to the Society. The remainder was later converted to Society property 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 Indian Wars.
