WW2 | Bletchley Park's U.S. (AT&T) Component

At the BookExpo America in New York City this week I picked up a book by William Bynum called A Little History of Science (Yale University Press, 2012).  It has nearly two pages on the use of computers in World War II, notably at Bletchley Park in England.

I have been comparing these pages with what I remember of The Imitation Game and two YouTube videos I just watched on how the German Enigma and Lorenz computers worked and how their codes were broken.

The Enigma worked on a 25-letter alphabet, whereas the Lorenz cryptography machine worked with the 32-character Baudot code. Hitler deliberately used the different Lorenz encryption for his top command.

The Bletchley group first cracked the Enigma code on July 9, 1941. But the sheer volume of messages required them to be constantly seeking more mechanicals ways of processing the coded messages that they received.

The report presented in A Little History of Science is consistent with the YouTube stories in giving virtually all the credit to the Bombe and Colossus machines - the Mark I and finally the Mark II, of which there were ten at Bletchley by 1944.

These machines worked through the Tunny machine (see p. 609 of the book to which a link is shown) to decrypt German messages.

The second YouTube video cited above ("How their codes were broken") references Bell Labs, which until the 1940s was in New York City; it later moved to New Jersey. Bell Labs was at the ] time a division of the American Telephone & Telegraph Company (AT&T), half-owned through its Western Electric manufacturing subsidiary. Researchers working at Bell Labs are credited with the development of radio astronomy, the transistor, the laser, information theory, the UNIX operating system, and several popular programming languages - C, S and C++. Eight Nobel Prizes have been awarded for work at Bell Labs.

The late Tom Collins (nicknamed "Sam Scram" at Bletchey after a popular radio character) of Springs, N.Y., worked for Western Electric, and personally accompanied the Dragon 1 cryptography machine to Bletchley during World War II.  I am wondering where the Dragon 1 and Dragon 2 (both of which he worked on) fit into Bletchley's history. Was the Dragon 1 generated by Bell Labs and then transferred to Chicago for operation? Just wondering.

Here are the top six links I got typing Tom's name and "Bletchley" into a Google search:

    OBIT | Nov. 12–Mavis Lever Batey, Codebreaker

    Mavis Lever Batey, 1921-2013 (Photo by Daily Telegraph).
    Nov. 12, 2013–Mavis Lever Batey died today at 92 years of age. Her knowledge of German from her studies at University College, London, was put to use during World War II to help break German codes based on their Enigma cryptography machine. (This post is based on Daily Telegraph and NY Times obits and on interviews with two people with Bletchley ties.)

    She is given major credit for British naval dominance over the Axis when information from the code-breakers at Bletchley Park (aka Station X or Ultra) enabled the Navy to identify the size and coordinates of Italian ships. The British sought out and sank three heavy Italian cruisers and two destroyers. For the rest of the war the stunned Italians stayed clear of the British Navy.

    Sir Francis Harry Hinsley, the official historian of British intelligence during World War II, has said that Bletchley Park's work shortened the war by two or more years.

    Mavis worked for Dillwyn Knox, known as Dilly. She married another code breaker, Keith Batey, in 1942. After World War  II he became the CFO of Oxford University. He died in 2010. She wrote books about Dilly and Ian Fleming (From Bletchley with Love) at Bletchley, and about the gardens of Oxford.

    (Update, May 21, 2014: I just found out that one of Ian Fleming's models for James Bond was Sir William Stephenson, the wartime intelligence liaison between Churchill and FDR; his code name was "Intrepid".  A plaque in honor of "Intrepid" has been posted on the 36th Floor of 30 Rockefeller Plaza, where Sir William had his office.  Other models for Bond reportedly were Fleming's brother, Peter, who had been involved in behind-the-lines operations in Norway and Greece during the war, Conrad O'Brien-ffrench, Patrick Dalzel-Job and Bill "Biffy" Dunderdale. A TV miniseries, "Fleming", is out this year.)

    The 2001 movie Enigma starring Kate Winslet is at least party based on Mavis Batey's wartime experience, although Ms. Batey complained that the women code breakers looked too scruffy in the movie.

    Bletchley Park employed 12,000 people, including some Americans. The story of "Sam Scram" -- Tom Collins, who died on May 18, 2012, is told in a post on this site on June 9, 2013.

    Bletchley Park's significance in WW2 would be hard to overstate.
    • Station X was where Alan Turing devised a way to break the Enigma code.
    • It was where the world's first computer, Colossus, was built.
    • It was where the battle of the Atlantic was won.
    • It saved many lives and shortened the war. 
    It is a building of such significance, but the secrecy that protected Bletchley Park throughout the war and for 30 years after it led to the site becoming forgotten. Bletchley Park Director Simon Greenish said:
    When you look at Hut 6, which is where the Bletchley story really started with the deciphering of Enigma codes, it's in quite a bad state. The floor has almost completely gone and I don't think it's an exaggeration to say that my garden shed is probably stronger than some of these huts.
    Once the home of financier Sir Herbert Leon, Bletchley was taken over during the war for use by the Government Code and Cypher School. After 1945, the site was used by the Post Office and other government bodies until 1991. At that point, the Bletchley Park Trust was established to maintain the site as a museum and Milton Keynes Borough Council declared most of the estate a conservation area.

    Greenish believes the huge public support, as shown by rising visitor numbers and online petitions, will help Bletchley Park receive the funds it deserves.
