About Joseph Dietzgen:
Peter Josef Dietzgen was a German socialist philosopher, Marxist and journalist. Joseph was born in Blankenberg in the Rhine Province of Prussia. He was the first of five children of father Johann Gottfried Anno Dietzgen (1794–1887) and mother Anna Margaretha Lückerath (1808–1881). He was, like his father, a tanner by profession; inheriting his uncle's business in Siegburg. Entirely self-educated, he developed the notion of dialectical materialism independently from Marx and Engels as an independent philosopher of socialist theory. His publications had major influences on Vladimir Lenin and the Russian Revolution of 1917, which are rarely commented on today. Ludwig Feuerbach's works had a great influence on his early theories. He had one son, Eugene Dietzgen.
