daughter, who proclaimed that Joseph had become "the Philosopher" of socialism. By 1870, Marx had embraced Dietzgen as a friend, and later praised him and his theory of dialectical materialism in the 2nd edition of the first volume of Das Kapital. On June 8, 1878, Dietzgen was arrested following the publication of a lecture he gave in Cologne: The future of the social democracy. He spent 3 months in prison on remand before his trial was held. Although Joseph was released along with copies of his article, he was re-arrested twice and finally released. In 1881 Joseph sent his son Eugene to the United States in order to avoid the Kaiser's upcoming army draft, to safeguard his articles and documents, as well as to secure a family home in the new world. Young Eugene was 19 when he arrived in New York, but quickly jump started a thriving family business in Chicago, the Eugene Dietzgen Company. It became one of the world's top drafting and surveying supply manufacturers and distributors and remained such through most of the 20th century. The company still exists today as a division of Nashua Paper, and its two buildings still stand in Chicago's now trendy Printer's Row and Lincoln Park areas. During this period, Eugene and Joseph kept in close contact through extensive letters which are currently being documented and published. In the same year, Joseph ran for the elections of the German Reichstag (the parliament), but emigrated in 1884 to New York City. He moved to Chicago two years later, where he became editor at the Arbeiterzeitung. Unfortunately Joseph's death in 1888 marked an end to his son's dependency, but his family line would continue to be part of some of the biggest engagements of the 20th century; from World War I, to the 1936 Berlin Olympics, to the heart of World War II. Dietzgen's words and life have for some underscored the unity that existed on the political left at the time of the First International, before Anarchists, Revolutionaries, and Social Democrats were later divided: "For my part, I lay little stress on the distinction, whether a man is an anarchist or a socialist, because it seems to me that too much weight is attributed to this difference." In this, he acted to reconcile anarchists and Marxists (see Anarchism and Marxism). Dietzgen was later figured on a stamp by the German Democratic Republic.
