About the author

Born in 1840 and dying in 1907, David J. Cook is remembered as a major law-enforcement figure in early Colorado. He served as Denver’s city marshal, sheriff of Arapahoe County, deputy U.S. marshal for Colorado, and a major general in the Colorado Militia.

Cook’s name is especially tied to the turbulent years when mining booms, labor unrest, and rapid growth tested frontier institutions. Archival records describe him as a central public-order figure, and his Wikipedia entry reflects the lasting regional attention given to his law-and-order career.

Although not primarily known as a literary author, he remains a vivid historical personality whose life offers a window into the realities of policing and power in the American West.
