Friedrich Engels was born in 1820 as the son of a successful German industrialist. As a young man his father sent him to England to help manage his cotton factory in Salford. Engels was shocked by the poverty in the city and began writing an account that was published as the "Condition of the Working Classes in England" (1844). His account includes a graphic description of the pauper burial ground at St. Michael's Flags. Engels later collaborated with Karl Marx, which resulted in the Communist Manifesto.
