Antonio Labriola
Antonio Labriola (; 2 July 1843 – 12 February 1904) was an Italian Marxist theoretician and philosopher. Although an academic philosopher and never an active member of any Marxist political party, his thought exerted influence on many political theorists in Italy during the early 20th century, including the founder of the Italian Liberal Party, Benedetto Croce, as well as the leaders of the Italian Communist Party, Antonio Gramsci and Amadeo Bordiga. He also influenced the Russian revolutionary and Soviet politician Leon Trotsky. Provided by Wikipedia
