Based on this paragraph, during what year was Hearst born?

Context:
Hearst died at the age of 70 in Washington, D.C., on February 28, 1891. The California Legislature and state courts adjourned so officials could attend his funeral. When Phoebe Apperson Hearst inherited her husband's wealth, she donated a great deal of it to help found new libraries at several universities. Hearst is buried in Cypress Lawn Cemetery in Colma, California. His widow and son were later buried there as well. The Hearst Memorial Mining Building on the Berkeley campus is dedicated to George Hearst. In 1996, he was inducted into the Hall of Great Westerners of the National Cowboy & Western Heritage Museum.<|im_end|>
