The Cushing Memorial Library, which houses Texas A&M University Archives, Special Collections, Rare Books, and Manuscripts, has a collection of Roy Fuller's correspondence with Julian Symons and Jack Clark, from 1937-1992.
Julian Symons was a British novelist, historian, critic, and poet (also born in 1912), best known for his crime and detective fiction. He founded and edited the literary journal Twentieth Century Verse, and wrote biographies of (among others) Charles Dickens, Thomas Carlyle, and Sir Arthur Conan Doyle. This, despite having left school at 14. Symons reviewed Reed's Collected Poems in 1991 for the Times Literary Supplement.
Box 1, folder 1480 of the Roy Fuller Correspondence contains a wartime letter which mentions Henry Reed:
1-1480: RF to Julian Symons. ALS, 1 leaf. Re: Henry Reed, visit to London, photograph to be made, illness. June 16, 1944.What is the mysterious "Re:" in reference to? Did Fuller meet Reed? Did Symons? Did they correspond? In 1944 Reed would have still been with the Foreign Office at Bletchley Park, but it seems perfectly reasonable they could have met up in London.
There's an excellent article on Fuller's early poetry in Poetry Nation, no. 6 (1976).
