Fitzgerald’s most famous book, "The Great Gatsby", was first sold in 1925. Fitzgerald travelled a lot at this time – mainly to France, where he met a number of other Americans who had left the United States. It was around this time that Fitzgerald first met Ernest Hemingway. They became good friends, but Hemingway did not like Fitzgerald’s wife, Zelda. Hemingway said that Zelda was insane, made Fitzgerald drink alcohol and that she did not allow him to do his best work. It is generally accepted, however, that Zelda had a big influence on Fitzgerald’s writing.
