 Lithuanian Americans have also distinguished themselves in the arts such as stained glass artist and painter Adolfas Valeška as well as modern artists such as Jonas Mekas, the avant-garde filmmaker and George Maciunas, founder of the Fluxus movement.Several fictional characters of Lithuanian birth who immigrated to the United States have prominently captured the American imagination.One is Jurgis Rudkus, a Lithuanian immigrant around whom Upton Sinclair's 1906 novel "The Jungle" chronicles the life of the Lithuanian community in Chicago and the treatment of workers in the Chicago Stockyards.
