In 1871, Amalia Post of Cheyenne, Wyoming Territory, became one of the first women to serve on a jury in the United States. Soon, she began advocating for women’s rights on a national level. She was an independent businesswoman from the time her first husband abandoned her in Denver in the early 1860s, through her marriage to her second husband, Cheyenne banker and politician Morton Post and up to the time of her death in 1897.

Was she a hard-drinking, swashbuckling mule skinner and Indian fighter? Or an alcoholic prostitute, stuck in menial jobs in a life both dreary and mundane? Calamity Jane's life is two stories: the facts of her biography, and the romantic tales that came to comprise the Calamity Jane legend.

Lillian Heath, Wyoming’s first woman physician, practiced medicine in and around Rawlins, Wyo., beginning in 1893. As a teenager, she trained with Union Pacific Railroad surgeon Dr. Thomas Maghee, and assisted Maghee and Dr. John Osborne in their post-mortem investigations into the brain of outlaw Big Nose George Parrot. Later she won a medical degree from the College of Physicians and Surgeons in Keokuk, Iowa, where she specialized in obstetrics. She retired after 15 years of practice, but remained keenly interested in medicine until her death in 1962.

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.

Lucy Morrison Moore, “The Sheep Queen of Wyoming,” was a leading sheep producer during the heyday of public-land sheep ranching from the 1880s to 1920s. Smart, tough and slightly eccentric, she and her family survived brutal, isolated conditions and attacks from cattle ranchers.
