Elected Secretary of State in 1946, Arthur Crane became acting Governor in 1949 at the age of 72. After his term as Governor he wrote many articles on education and was active in many education organizations.

Thomas Moonlight was elected State Senator for Leavenworth County in 1872 and then appointed Governor of Wyoming Territory by President Cleveland on January 5, 1887. Governor Moonlight took the oath of office January 24, 1887 serving until April 9, 1889

Though the site was an important river crossing on the early frontier, the town of Casper did not begin until 1888, when the Fremont, Elkhorn & Missouri Valley Railroad reached the area. The town immediately became an important shipping point for cattle and wool. The first oil refinery was built in 1895 to process crude oil from the Salt Creek Oil Field, 40 miles to the north. The first true oil boom began after 1910 and lasted through the mid 1920s, and the town’s fortunes have been closely connected to the energy business ever since. In 2010 the city’s population passed 55,000. Casper continues as a retail, medical and energy-industry service hub.

Billy Owen never saw a railroad until he was eight years old. His mother had told him about railroads. But in his mind as he traveled east by wagon train across Wyoming in the spring of 1868, he had imagined railroad wheels that looked something like wagon wheels. They rolled in grooves. Each groove was made by two rails. That meant it took four rails, as he imagined it, to make a track.

Casper’s Odd Fellows Building, constructed in 1952, reflects the modern-style architecture that was popular during the postwar era and serves as a reminder of the community development, planning and the social history of the time. This structure is named on the National Register of Historic Places.

Originally established as the Wyoming Insane Asylum by the Wyoming Territorial Legislature in 1886, the Wyoming State Hospital in Evanston opened in 1889 and operates today on the same site. The institution evolved and the campus was built according to trends in psychiatric thought and therapeutic practices. Notable among its superintendents was Dr. C.H. Solier, who ran the hospital from 1891 to 1930, and successfully deflected allegations of patient abuse in the 1920s.

The Ames Monument, a 60-foot-high granite pyramid, was completed in 1882 at the highest point on the Union Pacific Railroad, to honor railroad financiers Oakes and Oliver Ames. The tracks have since been moved, but the monument is still easily visible and accessible from Interstate 80 between Cheyenne and Laramie, Wyo.

Bessemer, Wyo., on the North Platte River west of Casper, was founded in 1888 but disappeared after failing to win the status of county seat of the brand-new Natrona County in 1890.

White settlement in Sublette County, Wyo. traces its roots to the late 1870s, when cattlemen brought herds to the pastures where North, Middle and Piney Creeks join the Green River. The town of Big Piney was incorporated there in 1913. The next year, neighboring Marbleton was incorporated a mile away, on higher ground on the bench above Piney Creek. Every effort to combine the two towns has failed, and they continue to maintain separate governments though they share most other services. The energy industry is now the major employer in both communities. Big Piney registered a population of 552 in the 2010 census, and Marbleton, 1,094.

Although the Teapot Dome Scandal of the 1920s was named for a Wyoming rock formation resembling a teapot, the wrongdoers were not from the state. During the administration of President Warren G. Harding, oilmen Harry Sinclair and Edward Doheny bribed Secretary of the Interior Albert Fall to gain access to the naval petroleum reserves located at Teapot Dome in the Salt Creek field north of Casper in northern Natrona County. Fall was the first Cabinet official to be imprisoned for crimes committed during his time in office. Sinclair also served a jail sentence.
