Ludwig Carl Moyzisch

A film based on the book Operation Cicero by L.C. Moyzisch was released by 20th Century Fox in 1952. It was titled 5 Fingers and directed by Joseph L. Mankiewicz. Bazna, renamed Ulysses Diello, was played by James Mason.

Moyzisch published his memoirs in 1950 with a book named Operation Cicero. Richard Wires, author of The Cicero Spy Affair stated that he found the book to be a "sensational narrative" with misrepresentations and omissions. Wires speculated that Moyzisch may not have known that Bazna was still alive. Franz von Papen and Allen Dulles, wartime head of the OSS, suggested that there was more to the story than what had emerged in the book. Neither elaborated. Twelve years later, in 1962, I was Cicero was published by 'Cicero' himself.

He had an official title of commercial attaché in Ankara, while secretly working there as SD chief. He reported to Walter Schellenberg while in Ankara during 1941–1944. Moyzisch lived in Ankara with his wife and son, but he was unable to get his mother and sister out of Germany. Schellenberg and Himmler were quite impressed by the efficient, professional, and friendly manner in which he worked. An SS officer intervened when an anonymous letter was sent to the regime stating that Moyzisch was part Jewish.

Ludwig Carl Moyzisch (born 1905) was a diplomatic attaché of the Nazi German Embassy in Ankara, Turkey in 1943. Under this cover, he led the work of the German secret services in Turkey, including Elyesa Bazna, codename 'Cicero'. Moyzisch wrote the book Operation Cicero in part to explain his role and activities working for the Sicherheitsdienst (SD). The book was subsequently adapted into the film 5 Fingers, starring James Mason as the spy.
