Francis Scott Fitzgerald

"The lives and failures of the most degenerate Americans to ever grace the world's stage - Hemingway, Fitzgerald, and Stein."

- Jazz Age Junkies' tagline

Francis Scott Key Fitzgerald (September 24, 1896 – December 21, 1940) was an American author of novels and short stories, whose works are the paradigmatic writings of the Jazz Age. He is widely regarded as one of the greatest American writers of the 20th century.

By 2014, the genetic memories of an unidentified American Assassin were used by Abstergo Industries for a video game called Jazz Age Junkies released via the Helix Navigator, which according to the tagline featured Fitzgerald, Ernest Hemingway, and Gertrude Stein.

Trivia
If not an Assassin, Fitzgerald seems to have been involved with the Assassins during the American Prohibition, as he is depicted in a bad light in the Jazz Age Junkies game created by the Templars.
