McCook served as the 5th and 7th Governor of Colorado Territory. From Wikipedia; “On June 14, 1869, President Ulysses S. Grant appointed Edward M. McCook as the fifth governor of the Colorado Territory. McCook served during a critical period leading up to Colorado’s statehood in 1876…McCook’s administration coincided with the early years of irrigation development along the Front Range. During this period, communities began constructing many of the ditches and diversion systems that later became the foundation of Colorado’s prior-appropriation water rights system. The rapid agricultural growth of the 1870s was already underway by the time he took office…McCook was born in Steubenville, Ohio, on June 15, 1833. As a young man, he moved to the Kansas Territory and became a lawyer. He joined the Pike’s Peak Gold Rush in 1859 and represented the Pikes Peak region in the Kansas Territorial House of Representatives…In 1869, President Ulysses S. Grant appointed McCook Governor of the Territory of Colorado, a selection bitterly opposed by Jerome B. Chaffee, the Colorado Territorial Delegate to the United States House of Representatives. During his tenure, Governor McCook signed the legislation that created Colorado Agricultural College (now Colorado State University) and was among the first territorial governors to endorse women’s suffrage.”
