Marx's surviving daughters Eleanor and Laura, as well as Charles Longuet and Paul Lafargue, Marx's two French socialist sons-in-law, were also in attendance. He had been predeceased by his wife and his eldest daughter, the latter dying a few months earlier in January 1883. Liebknecht, a founder and leader of the German Social Democratic Party, gave a speech in German and Longuet, a prominent figure in the French working-class movement, made a short statement in French. Two telegrams from workers' parties in France and Spain were also read out. Together with Engels's speech, this constituted the entire programme of the funeral. Non-relatives attending the funeral included three communist associates of Marx: Friedrich Lessner, imprisoned for three years after the Cologne Communist Trial of 1852; G. Lochner, whom Engels described as "an old member of the Communist League"; and Carl Schorlemmer, a professor of chemistry in Manchester, a member of the Royal Society and a communist activist involved in the 1848 Baden revolution. Another attendee of the funeral was Ray Lankester, a British zoologist who would later become a prominent academic.
