Spandau Prison
Of the seven, only four served all of their sentence; the remaining three, Neurath, Raeder, and Funk, were released early due to ill health. Between 1966 and 1987, Rudolf Hess was the only inmate in Spandau Prison. His only companion was the warden, Eugene K. Bird, who became a close friend. Bird wrote a book about Hess's imprisonment entitled The Loneliest Man in the World.
