Karl Höchberg (8 September 1853 – 21 June 1885) was a German social-reformist writer, publisher and economist, who acted under the pseudonyms Dr. Ludwig Richter and R.F. Seifert. In 1876, he became a member of the Socialist Workers' Party of Germany (SAPD). From 1877 to 1878, he was responsible for editing the Zukunft ("Future") magazine. He was in exile in Switzerland from 1878 onwards, due to the anti-socialist laws (during the early time of this exile Eduard Bernstein and Karl Kautsky were his secretaries and pupils in Zurich). Afterwards, between 1879 and 1881, he was editor of the Jahrbuch für Sozialwissenschaft und Sozialpolitik ("Yearbook for Social Science and Social Politics").
