Karl Lueger was the most important mayor in the time of Emperor Franz Josef. During his time important community plans were realized that made Vienna a modern city. However, Lueger was a radical anti-Semite. He was admired by the young Adolf Hitler, who spent some years before the First World War in Vienna. At this time, Vienna was an important place for the arts. Composers like Arnold Schönberg, Anton Webern, Alban Berg and Ernst Krenek were important for the development of modern music. Also the psychoanalysis was founded in Vienna by Sigmund Freud. Also the so-called Jugendstil in arts was part of Vienna's modern arts scene. Founding fathers of modern architecture lived and worked also in Vienna at this time (Otto Wagner, Adolf Loos)
