It was here that Hitler first became exposed to racist rhetoric.  Populists such as mayor Karl Lueger exploited the climate of virulent anti-Semitism and occasionally espoused German nationalist notions for political effect. German nationalism had a particularly widespread following in the Mariahilf district, where Hitler lived.  Georg Ritter von Schönerer became a major influence on Hitler.  He also developed an admiration for Martin Luther .  Hitler read local newspapers such as Deutsches Volksblatt that fanned prejudice and played on Christian fears of being swamped by an influx of Eastern European Jews.  He read newspapers and pamphlets that published the thoughts of philosophers and theoreticians such as Houston Stewart Chamberlain , Charles Darwin , Friedrich Nietzsche , Gustave Le Bon and Arthur Schopenhauer .
