New York: [E. Dietzgen], 1896. First Edition. Transcripts of two lectures by Joseph Dietzgen and his son Eugen respectively, including what is apparently the first appearance in America of Joseph Dietzgen's influential essay "Die Zukunft der Socialdemokratie" ("The Future of Democratic Socialism"), first delivered as a lecture in Koln in 1878. The essay, highly critical of Bismarck and the Hohenzollern Empire, resulted in Dietzgen's incarceration on charges of sedition. He was released the following year and not long afterwards emigrated to the United States. Following Dietzgen's death in 1888 his son Eugen (founder of the highly successful and still flourishing Dietzgen drafting supply company) became the major proponent and publisher of his socialist philosophy.
