The literary figures of the Lost Generation tended to use common themes in their writing. One of those themes is decadence and the frivolous lifestyle of the wealthy. Both Hemingway and Fitzgerald touch on this theme throughout their novels, The Sun Also Rises and The Great Gatsby. Another theme that common among these authors was the death of The American Dream, as in Steinbeck’s Grapes of Wrath and Cannery Row.
The Lost Generation came of age during the Roaring Twenties, then faced the despair of the Great Depression. It included writers such as F. Scott Fitzgerald, T. S. Eliot, John Steinbeck, William Faulkner, James Joyce, Sherwood Anderson, John Dos Passos, Henry Miller, Aldous Huxley, Malcolm Cowley and others. – WIKIPEDIA
