Fleming, seen in above photo, published Goldfinger in 1959. The original book jacket for Goldfinger is seen below:
Macintyre, who is the author of the true World War II espionage story, Operation Mincement, and For Your Eyes Only: Ian Fleming and James Bond, a book that celebrated the Fleming centenary celebration, notes that Fleming was fascinated by the interplay between truth and fiction.
"Everything I write has a precedent in truth," Fleming said.
Macintyre notes that in World War II a Nazi agent planned to rob the Bank of England, and perhaps this gave Fleming the idea of Goldfinger palns to rob Fort Knox.

And below is the cover of the Signet paperback of Goldfinger in the 1960s and a great passage from Ian Fleming's thriller:
"Yes," Goldfinger nodded. "That is exactly what we are going to do. We are going to burgle fifteen billion dollars' worth of gold bullion, approximately half the supply of mined gold in the world. We are going, Mr. Bond, to take Fort Knox."
