The "Lost Generation" refers to a group of American writers and artists who came of age during and after World War I. Disillusioned by the war and the societal changes that followed, they often expressed feelings of alienation and disconnection in their works. Notable figures include Ernest Hemingway, F. Scott Fitzgerald, and Gertrude Stein, who explored themes of loss and the search for meaning in a rapidly changing world. This term was popularized by Gertrude Stein, who described her contemporaries as a generation that felt lost in the aftermath of the war. Their literature often critiqued the values of mainstream society, reflecting a sense of moral ambiguity and questioning traditional norms. The Lost Generation's influence continues to resonate in modern literature and culture.
