expressed his deep gratitude to the Bletchley Park codebreakers soon after the Nazis surrendered. The letter has been kept under wraps all these 70 years.
It might be a good time for Bletchley Park to acknowledge more completely the role of Americans in assisting with their work. I am thinking of the shipment of the Dragon 1 computer to Bletchley, for example. My neighbor Capt. Tom Collins was selected from his life's work with Western Electric and given special training to accompany the computer. He spent a year helping the Bletchley team make use of it. James Brady wrote in Forbes Magazine how proud Tom was of his wartime role.
The full story of the use of the American code-breaking equipment has not been told.
