In the 1820s and 1830s, what’s now western Wyoming was at the center of the fur trade of the northern Rocky Mountains. Indians, trappers and their suppliers met each summer at a big trade fair called rendezvous, where trappers exchanged their season’s beaver pelts for hardware, whiskey and supplies. By 1840, demand for beaver had disappeared and the species had been nearly rubbed out. But the rendezvous supply routes were already becoming the trails that would bind the nation together.

Fort Fetterman was established by the U.S. Army on the North Platte River near present Douglas, Wyo. in 1867. It served as a staging point for Gen. George Crook’s three campaigns against Cheyenne and Lakota Sioux Indians in 1876, near the end of the Indian Wars. The Army abandoned the post in 1882, and the settlement finally closed down a few years later when the railroad arrived at Douglas, seven miles to the south.

In 1869, Fort Fred Steele was built by the U.S. Army to protect workers on the advancing transcontinental railroad at the spot where the rails crossed the North Platte River. The fort was closed in 1886, and the site, containing foundations of the original buildings, was much later acquired by the state.

Fort Laramie began as a fur-trade post in 1834 near the confluence of the Laramie and North Platte rivers. Soon it changed into a post for the trade in buffalo robes, and for supplying emigrants bound west on the Oregon/California/Mormon Trail. In 1849 the post was purchased by the U.S. Army, and became an important supply, logistics and communications center for the Indian Wars campaigns of the next four decades. In recent decades the post has been carefully restored, and today is a National Historic Site.

The Fetterman Battlefield, southeast of present Story, Wyo., marks the spot where Capt. William Fetterman and all 80 men under his command were killed Dec. 21, 1866 by Lakota Sioux, Cheyenne and Arapaho Indians.

Fenimore Chatterton was born in Oswego County, New York on July 21, 1860. Chatterton was raised in Washington, D.C. where he attended public schools. After attending Columbian University (now George Washington University) Chatterton graduated from Millersville State Normal School in Lancaster, PA. He moved to Wyoming in 1878 and became a clerk in a general mercantile and banking concern.

A childhood love of adventure eventually led the Belgian Jesuit priest Father Pierre-Jean De Smet to become a missionary to the Indians of the Rocky Mountains. He traveled throughout the northern Rockies, along the way celebrating the first Catholic Mass in what’s now Wyoming on July 5, 1840, during the Green River Rendezvous. In 1851, members of his party named Lake De Smet for him as they traveled from the Missouri River in present Montana to assist in treaty negotiations with the plains tribes near Fort Laramie.

On September 2, 1885, long-simmering tensions between white and Chinese coal miners in Rock Springs, Wyoming Territory, boiled over into a massacre in which whites murdered 28 Chinese, wounded 15 more, and looted and burned all 79 shacks and houses in Rock Springs’ Chinatown. Though the remaining Chinese miners wanted desperately to leave Wyoming, the Union Pacific Railroad, which owned the mines, refused to grant them railroad passes or the back pay owed them. The Chinese finally had no choice but to return to work, which kept wages low and the coal flowing from the mines.

The Welsh-born Episcopal priest John Roberts arrived in 1883 at Fort Washakie on what’s now the Wind River Indian Reservation in Wyoming, became a friend of the Shoshone chief Washakie, and served the Shoshone and Arapaho people with a loving paternalism well into his old age. John Roberts died in 1949.

Emma Knight, the University of Wyoming’s first dean of women, bore four children and served seven years as the Albany County, Wyoming superintendent of schools before she finally graduated from the university in 1911, the same year as her daughter. The wife and mother of UW professors of geology—Wilbur and Samuel H. Knight—she was highly regarded by her students and colleagues. Knight Hall on the UW campus is named in her honor.
