Context: Hearst was born near present-day Sullivan, Missouri, to William G. Hearst and Elizabeth Collins, who were of Scots-Irish ancestry. Hearst, one of three children — two boys and a girl – was raised in a log cabin on his family's farm in rural Franklin County. His father operated three small farms, all of which were mortgaged. William Hearst sold his products in his own local general store. George Hearst grew up before public education was widely available in Missouri, meaning his elementary education was inconsistent and fragmented. Becoming interested in mining, Hearst supplemented the gaps in his formal education by observing the local mines, reading information about minerals from books owned by his family doctor, Silas Reed, and mining in his free time.
