James Fenimore Cooper was born in 1789 in New Jersey to a wealthy family. He was educated locally and briefly attended Yale but was expelled. He then joined the US Navy and served from 1806-1809. After inheriting his family fortune in 1811, he married and began writing novels for income after his brothers died. His first novel The Spy was published in 1821 and was successful, leading him to pursue writing as a career. He is best known for The Leatherstocking Tales series featuring frontiersman Natty Bumppo, beginning with The Pioneers in 1823. Though criticized in his later years, Cooper made significant contributions to the development of the American novel.
