Boris Vian (10 March 1920 – 23 June 1959) was a French polymath: writer, poet, musician, singer, translator, critic, actor, inventor and engineer. He is best remembered today for his novels. Those published under the pseudonym Vernon Sullivan were bizarre parodies of criminal fiction, highly controversial at the time of their release. Vian's other fiction, published under his real name, featured a highly individual writing style with numerous made-up words, subtle wordplay and surrealistic plots. L'Écume des jours (Froth on the Daydream) is the best known of these works, and one of the few translated into English.
