Ralph Rumney (5 June 1934 – 6 March 2002) was an English artist, born in Newcastle Upon Tyne. In 1957 lifelong conscientious objector Rumney - he evaded National Service by going on the run in continental Europe - was one of the co-founders of the London Psychogeographical Association. This organization was, along with COBRA and the Lettrist International, involved in the formation of the Situationist International. Amongst those present at the founding in the Italian village of Cosio d'Arroscia were Walter Olmo, Michèle Bernstein (later his second wife) Asger Jorn, and Guy Debord. However, within seven months Rumney had been 'amiably' expelled from the SI by Debord for allegedly "failing to hand in a psychogeography report about Venice on time."
