Francis Scott Key Fitzgerald (September 24, 1896 - December 21, 1940), known professionally as F. Scott Fitzgerald, was an American novelist and short story writer, whose works illustrate the Jazz Age. He is widely regarded as one of the greatest American writers of the 20th century. He finished four novels: This Side of Paradise, The Beautiful and Damned, The Great Gatsby, and Tender Is the Night. A fifth, unfinished novel, The Love of the Last Tycoon, was published posthumously. Fitzgerald also wrote numerous short stories, many of which treat themes of youth and promise, and age and despair. Paris in the 1920s proved the most influential decade of Fitzgerald's development. Fitzgerald made several excursions to Europe, and became friends with many members of the American expatriate community in Paris, notably Ernest Hemingway. Fitzgerald's friendship with Hemingway was quite effusive, as many of Fitzgerald's relationships would prove to be. Like most professional authors at the time, Fitzgerald supplemented his income by writing short stories for such magazines as The Saturday Evening Post, Collier's Weekly, and Esquire, and sold his stories and novels to Hollywood studios. Fitzgerald claimed that he would first write his stories in an 'authentic' manner, then rewrite them to put in the "twists that made them into salable magazine stories." Although Fitzgerald's passion lay in writing novels, only his first novel sold well enough to support the opulent lifestyle that he and his wife Zelda adopted as New York celebrities. The Great Gatsby, did not become popular until after Fitzgerald's death.
