Harry Yount
Henry S. Yount was an American Civil War soldier, mountain man, professional hunter and trapper, prospector, wilderness guide and packer, seasonal employee of the United States Department of the Interior, and the first gamekeeper in Yellowstone National Park. He was nicknamed Rocky Mountain Harry Yount.
There are conflicting accounts of Harry Younts place and date of birth. Ernest Ingersoll wrote that he was born in Susquehanna County, Pennsylvania, and different birth years have been mentioned by various writers, such as the anonymous author of a published biographical sketch who wrote that Yount was born in 1847, and Thomas J. Bryant, who interviewed Yount in the latter years of his life and speculated that 1837 was his birth date in an article published in the Annals of Wyoming, journal of the Wyoming State Historical Society. However, research undertaken by William R. Supernaugh, an employee of the National Park Service, found military enlistment papers, Younts Army pension file, and the 1840 United States Census records, all of which indicate that Yount was born on March 18, 1839. These records also show that his legal name was Henry S. Yount. His lifelong nickname was Harry, and his middle name is unknown.
