Francis Scott Key Fitzgerald was born on September 24, 1896. He was an American writer of novels and short stories, whose works are the typical writings of the Jazz Age, a term he created himself. Born into an upper middle-class Irish Catholic family, Fitzgerald was named after his famous second cousin, Francis Scott Key. He was also named after his deceased sister Louise Scott, one of two sisters who died shortly before his birth. He spent 1898-1901 in Syracuse and 1903-1908 in Buffalo, New York, where he attended Nardin Academy. When his father was fired from his company, the family returned to Minnesota, where Fitzgerald attended St. Paul Academy from 1908 to1911. He is widely regarded as one of the 20th century's greatest writers. Fitzgerald is considered to be 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 classic novel, The Great Gatsby. A fifth, unfinished novel, The Love of the Last Tycoon was published after his death. Fitzgerald also wrote many short stories that dealt with themes of youth. His first literary work, a detective story, was published in a school newspaper when he was 12. When he was 16, he was forced to leave St. Paul Academy for neglecting his studies. He attended Newman School, a prep school in Hackensack, New Jersey, in 1911-1912, and entered Princeton University in 1913 as a member of the Class of 1917. There he became friends with future critics and writers Edmund Wilson (Class of 1916) and John Peale Bishop (Class of 1917), and wrote for the Princeton Triangle Club. He was also a member of the University Cottage Club, which still displays Fitzgerald's desk and writing materials in its library. A poor student, Fitzgerald left Princeton to enlist   in the US Army during World War I; however, the war ended shortly after Fitzgerald's enlistment. Fitzgerald had been an alcoholic   since his college days, leaving him in poor health by the late 1930s. Fitzgerald suffered a mild attack of tuberculosis in 1919, and died of a heart attack in 1940.
