Who dated Hildegard Knef?

Hildegard Knef, dite parfois Hildegarde Neff, née à Ulm le 28 décembre 1925 et morte à Berlin le 1^er février 2002, est une actrice, chanteuse et compositrice.

Boris Vian (French: [bɔʁis vjɑ̃]; 10 March 1920 – 23 June 1959) was a French polymath who is primarily remembered for his novels. Those published under the pseudonym Vernon Sullivan were bizarre parodies of criminal fiction, highly controversial at the time of their release owing to their unconventional outlook.

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. His novel Froth on the Daydream (L'Écume des jours) is the best known of these works and one of the many translated into English.

Vian was an important influence on the French jazz scene. He served as liaison for Hoagy Carmichael, Duke Ellington and Miles Davis in Paris, wrote for several French jazz-reviews (Le Jazz Hot, Paris Jazz) and published numerous articles dealing with jazz both in the United States and in France. His own music and songs enjoyed popularity during his lifetime, particularly the anti-war song "Le Déserteur" (The Deserter).
