André Breton, Louis Aragon, Paul Eluard, Robert Desnos, Philippe Soupault, Raymond Queneau, Antonin Artaud, René Char, René Crevel, for a while Georges Bataille and Michel Leiris, and some more lesser-knowns.
(To answer your question, Ionesco and Vian were a couple of decades later, but definitely influenced by the movement.)
André Breton, the "pope of Surrealism" considered himself to have launched it as a literary movement with
Les Champs magnétiques [The Magnetic Fields] in 1920. Written with Soupault, it was the first piece of "automatic writing." They drew their inspiration from pre- or proto-Surrealists of the 19th c.: Lautréamont, Jarry; and the Dada movement in Switzerland, with notably Tristan Tzara (who wasn't much of a pen, in truth).
Interesting thing is, they were all a bunch of mid-20somethings and were friends. They went to the same cafés, they met up and held seances, they did automatic writing experiments (different speeds, different states of mind, sleep-writing, etc.), they went to the movies together. Eluard stole Max Ernst's wife (who, years later, would then marry Salvador Dalí). Etc.
To get a lot and an overview read their literary review,
La Révolution Surréaliste (and ten years later, Bataille's
L'Acéphale). Read Breton's
Nadja.
