Friedrich Engels (1820-95) was born into a prosperous business family in Barmen near Dusseldorf. Although apprenticed to his father’s business firm, Engel’s sympathies moved quickly in the direction of Communism, an orientation which was cemented by the beginning of his lifelong collaboration with Marx in 1844. They jointly published The Communist Manifesto on the eve of the 1848 revolutions. In 1850 Engels moved to Manchester where he eventually became a partner in his father’s firm, continuing to help Marx who was engaged in writing Das Kapital. On retirement in 1870, he settled in London from where his books such as Anti-Dühring had an immense influence on the nascent Marxist movement.
