Born Trier, Germany (then Prussia). Died Maitland Park Road, Hampstead. Lived briefly in Brussels.
From the Institute for Fiscal Studies: "Marx lived for a time after arriving in London in 1849 at 4 Anderson St, Chelsea, before moving briefly to a German hotel in Leicester St, off Leicester Square, and then to lodgings at 28 Dean Street, Soho, which are marked by a blue plaque. In 1856 the family moved on to 9 Grafton Terrace in Kentish Town, in 1864 to 1 Modena Villas, Maitland Park and then in 1875 to 41 Maitland Park Road, Hampstead where he later died. The Reading Room where he worked (at seat G7) can be found in the atrium of the British Museum. . . .. An impressive monument can be found at his gravesite in Highgate Cemetery."
The Marxes were very poor and it was only money from Engels which freed Marx to write Das Kapital.
