Civil engineer, librarian, athlete, professor and historian, Grace Hebard gained early power at the University of Wyoming, serving on its board of trustees and later its faculty over a 40-year career. Though many scholars now question her scholarship, she remains best known for her books on Wyoming’s past. 

Lora Nichols of Encampment, Wyo., got a camera for her 16th birthday in 1899 and kept snapping photos until her death at age 78. Her work leaves a vivid record of her time and place, and of her clear-eyed vision of the lives of her neighbors and kin.

Clabe Young came with his brothers from Texas to Wyoming Territory in the late 1870s and cowboyed for prominent ranchers including Tom Sun and Boney Earnest. The Young brothers fell under suspicion of rustling by the powerful Wyoming Stock Growers Association, whose leaders hired a Chicago detective, John Finkbone, to set the matter straight.

Seeking a shorter way to the goldfields of Montana Territory, former prospector John Bozeman traced a route through the Powder River Basin—prized buffalo grounds for the resident tribes. A few hundred emigrants used the route between 1863 and 1866; later, as tribal resistance grew, it became primarily a military road.

The voluble, gregarious Teno Roncalio of Rock Springs, Wyo., a Democrat, became a powerful and effective figure in the state’s political landscape, serving five terms in the U.S. House of Representatives during the 1960s and 1970s.

In 1864, Jim Bridger blazed a trail to the Montana gold fields. It stayed west of the Bighorn Mountains to avoid trouble with Indian tribes. Wagons traveled the full route only that year, but in later decades it became an important way into the Bighorn Basin for white settlers.

Two military posts were built a few miles apart during the Indian Wars near the strategic Bozeman Trail crossing of Powder River—Fort Reno in the 1860s and Cantonment Reno in the 1870s. The first was one of three forts whose existence provoked the tribes into war. The second was an important Army base for later campaigns.

Jim Bridger’s skills as guide, mapmaker and businessman were unmatched. After 20 years trapping beaver in the northern Rockies, he co-founded Fort Bridger in 1843. In the 1850s and 1860s he guided important government exploring expeditions and guided troops on Indian campaigns. In 1868 he retired to Missouri, where he died in 1881.

News stories published about the July 20, 1889, hanging of Ella Watson and Jim Averell contained inaccuracies that historians and others accepted as fact for more than 100 years, leading to a variety of misunderstandings and resulting in questions about truth and history that haunt researchers today.

Train robber and confessed murderer Big Nose George Parrott was lynched in downtown Rawlins, Wyo. in 1881, after he tried to break out of jail. Later, local physician and future Wyoming Gov. Dr. John Osborne had a pair of shoes made from the outlaw’s skin.
