Walter Schellenberg
The story of what happened at Salon Kitty first came to light in Walter Schellenberg's memoirs, published in Germany in 1956 under the title "The Labyrinth". Peter Norden later expanded the story in his 1973 book "Madam Kitty". This book became the basis for the highly controversial 1976 film "Salon Kitty", directed by Tinto Brass and starring Helmut Berger as Walter Schellenberg (renamed Helmut Wallenberg) and Ingrid Thulin as Kitty Schmidt (renamed Kitty Kellermann).
