Friedrich Engels (28 November 1820 – 5 August 1895) was a German industrialist, social scientist, author, political theorist, philosopher and father of Marxist theory alongside Karl Marx. In 1845, he published The Condition of the Working Class in England, based on personal observations and research. In 1848, he produced with Marx The Communist Manifesto (which was based on Engels' The Principles of Communism) and later supported Marx financially to do research and write Das Kapital. After Marx's death, Engels edited the second and third volumes. Additionally, Engels organized Marx's notes on the "Theories of Surplus Value" and this was later published as the "fourth volume" of Capital.
