premiere on 2 February 1894. The play was widely successful. It shows many of the features found in "New Tracks," but also a focus on internal psychological processes. He produced several other dramas through the 1890s, with his last published play, "Weigand" appearing in 1906. Between 1900 and 1914 Schlaf wrote ten novels. His works show the influence of his readings of Whitman and Ernst Haeckel as well as traces of turn of the century decadence. In 1904, Schlaf moved to Weimar. During the Weimar Republic Germany's defeat in the First World War was a great blow to national pride, but they did not significantly alter the ideas developed by Schlaf. Like other authors of the period, he threw himself into his literary work – devoting himself to philosophical and cosmological speculation. During the war he had developed ideas connecting war with evolutionary selection as well as patriotic ideas of German cultural hegemony. During this time there developed a contradiction between the relative lack of success of his recent writings and the growth of his public recognition. Especially during birthdays, Schlaf was celebrated in public ceremonies, commemorated in the naming of streets, the foundation of a "Society of the Friends of Johannes Schlaf" and the construction of a museum. During the Third Reich In the 1930s Schalf confessed to the creed of National Socialism. Before the First World War, Schlaf's naturalism extended into racial aspects, but the vague concept of a Germanic race could apply to virtually every European nation. After the war, Schlaf's notions of biological evolution extended to the superiority of the German people. After the Nazi takeover in May 1933, Schlaf was appointed to the "cleaned" Prussian Academy of Arts.. In October of that year, Schlaf was among the 88 writers who signed the "vow of most faithful allegiance." He aligned with the Nazis to his death. Schlaf returned to Querfurt in 1937. His late writings focused on the Geocentric model and cosmological speculation and remain mostly unpublished. He continued to be honored by numerous awards in his late age, especially for his early works as a naturalist writer. He died at age 78, and high representatives from the National Socialist government attended his funeral. His papers are held by the State Library in Dortmund.
