This year marks the 125th anniversary of the founding of the City of Gillette. Although relatively young, this city has seen tremendous change from 1891 to today. The first period of great change occurred in what is often referred to as the “cowtown” era in Gillette history from 1891 to 1916. Life in the city during this time was marked by wildness, violence, disaster, and many other growing pains. Despite these rough years, the citizens of Gillette persevered and continued to invest in their new community. Gillette: The First 25 Years tells the story of the industries, people, and events that created Gillette and established it as a permanent city on the high plains of northeast Wyoming.
