Wilhelm Liebknecht
Wilhelm Liebknecht was a member until 1865, but as the ADAV tried to cooperate with Otto von Bismarck's government, for example on the question of women's suffrage, Liebknecht became disillusioned with the association. He had been writing for "Der Sozial-Demokrat," but as a result of disagreement with the newspaper's Prussia-friendly rhetoric he quit the organization to establish the Saxon People's Party along with August Bebel. In 1869, Liebknecht became a co-founder of the SDAP in Eisenach as a branch of the International Workingmen's Association.
