Having been involved in Dadaism from 1919 to 1924, he became a founding member of Surrealism in 1924,[REF] with André Breton and Philippe Soupault under the pen-name "Aragon".
The French surrealists had long claimed Lewis Carroll as one of their own, and Aragon published his translation of The Hunting of the Snark[REF] in 1929, "shortly before he completed his transition from Snarxism to Marxism", as Martin Gardner puts it [REF].
