Friedrich Engels (German pronunciation: [ˈfʁiːdʁɪç ˈɛŋəls]; 28 November 1820 – 5 August 1895) was a German social scientist, author, political theorist, philosopher, and father of communist theory, alongside Karl Marx. Together they produced The Communist Manifesto in 1848. Engels also edited the second and third volumes of Das Kapital after Marx's death.
Socialism: Utopian and Scientific is a short book first published in 1880 by German-born socialist Friedrich Engels. The work was primarily extracted from a longer polemic work published in 1878, Anti-Dühring. It first appeared in the French language.
The title Socialism: Utopian and Scientific was adopted for the first English edition — the tenth language in which the book appeared. Intended as a popularization of Marxist ideas for a working class readership, the book was one of the fundamental publications of the international socialist movement during the late 19th and early 20th centuries, selling tens of thousands of copies and books.
