When his marriage to Valentine ended he returned to London and began work organising the International Surrealist exhibition in 1936 and later co-founded the ICA. He met Lee Miller in 1937 and they married in 1947. In 1966 Roland was knighted for his services to modern art in Britain.
Roland’s significant art collection is managed at Farleys with works being loaned to exhibitions and licensed for reproduction. The majority of Roland’s archive of books and papers are held at the National Galleries Scotland which cares for a world-class collection of material on Surrealism.
