If it weren’t for Richard Howard‘s translations, I would not have been able to read numerous important books, among them the following:
Roland Barthes’ Camera Lucida, Mourning Diary, Roland Barthes by Roland Barthes, and Mythologies: The Complete Edition
André Breton’s Nadja
Michel Butor’s Mobile
Emil Cioran’s The Trouble with Being Born, A Short History of Decay, and Drawn and Quartered
Gilles Deleuze’s Proust and Signs
Michel Foucault’s Madness and Civilization: A History of Insanity in the Age of Reason
Alain Robbe-Grillet’s Jealousy, In the Labyrinth, The Voyeur, Repetition, and The Erasers
Stendhal’s The Charterhouse of Parma
I am likely forgetting other books. In any case, Howard enlarged and enriched the literary world, moreover the so-called real world as a whole.
