Edith Kirkwood Ormsby Clark was Wyoming State Superintendent of Public Instruction from 1915 to 1919. She arrived in Wyoming in 1906 to visit her uncle, L.R.A. Condit. She took up a teaching position at the EK School in Johnson County and was elected county superintendent of schools for Sheridan County before moving to Cheyenne to take up a state level position. In 1918 she went to France to serve with the YMCA. After retiring from state government, she homesteaded in Johnson County. She died in 1936. Collection contains diaries created by Edith K.O. Clark from 1906-1924, 1931, and 1934-1936. In addition to a daily log of Clark's activities, the diaries contain photographs of people, churches, ranches, horses, hunting and camping trips.

#Always Archiving

More than 100 years ago, Grace Raymond Hebard—UW faculty member, administrator, librarian, and Wyoming historian—began collecting the papers and reminiscences of Wyoming’s pioneers. Her research on the history of Wyoming, the West, emigrant trails, and Native Americans became the nucleus for what is known today as the American Heritage Center (AHC). Officially established in 1945, the Center now holds over 90,000 cubic feet of historic documents and artifacts in more than 3500 collections—placing the AHC among the largest non-governmental archives in the nation.

Today, the AHC contains important holdings in numerous areas. Its western history archives include materials on early women’s suffrage and political achievements, native Americans, ranching, politics, authors, and under-documented communities. Other featured collecting areas include transportation (railroad, highway and air travel), mining and energy extraction, entertainment and popular culture (with important collections featuring Hollywood, music, radio, television and the comic book industry), natural resources and the environment, and military history. The AHC also serves as the primary archives for the University of Wyoming.
