Francis Scott Key Fitzgerald (September 24, 1896 – December 21, 1940) was an American author of novels and short stories, whose works are the paradigm writings of the Jazz Age, a term he coined himself. He is widely regarded as one of the greatest American writers of the 20th century. Fitzgerald is considered a member of the "Lost Generation" of the 1920s. He finished four novels: This Side of Paradise, The Beautiful and Damned, Tender Is the Night, and his most famous, The Great Gatsby. A fifth, unfinished novel, The Love of the Last Tycoon, was published posthumously. Fitzgerald also wrote many short stories that treat themes of youth and promise along with despair and age.

Both The Great Gatsby and Tender Is the Night were made into films, and in 1958 his life from 1937–1940 was dramatized in Beloved Infidel.

Born in 1896 in Saint Paul, Minnesota to an upper middle class Irish Catholic family, Fitzgerald was named after his famous second cousin, three times removed, Francis Scott Key, but was referred to as "Scott." He was also named after his deceased sister, Louise Scott, one of two sisters who died shortly before his birth. "Well, three months before I was born," he wrote as an adult, "my mother lost her other two children....I think I started then to be a writer.". His parents were Mollie (McQuillan) and Edward Fitzgerald.
