Ferdinand August Bebel was a German socialist politician, writer, and orator. He is best remembered as one of the founders of the Social Democratic Workers' Party of Germany in 1869, which in 1875 merged with the General German Workers' Association into the Socialist Workers' Party of Germany. During the repression under the terms of the Anti-Socialist Laws, Bebel became the leading figure of the social democratic movement in Germany and from 1892 until his death served as chairman of the Social Democratic Party of Germany.
