Re: [BPARK] Fwd: BOOK : "Lorenz : Breaking Hitler's Top Secret Code at Bletchley Park" by Jerry Roberts

Hello all,

The book is indeed published posthumously by Captain Jerry Roberts=E2=80=99=
 wife Mei Roberts. Jerry Roberts completed his Tunny memoirs shortly =
before he died in March 2014. That Amazon lists Jerry Roberts as the =
author of several other books in a quirk of Amazon. Their author =
database is extremely crude simply listing all authors happening to have =
the same name. Shall we believe Amazon then there is at least 520 books =
attributed to the prolific author Jerry Roberts et al.

This book is of course not the official history of breaking Tunny at =
Bletchley Park, however I think and I hope that it might fill in some of =
the areas that often official histories leaves blank or neglected, the =
histories behind the scene. The  personal histories of those who =
actually did the work each day.=20

The history of BP breaking the Lorenz machine has not yet been fully =
explored. What is missing is of course The Testery Report or as it is =
entitled: =E2=80=9CSolution of German Teleprinter Cyphers (Testery) =
Linguistic Methods,=E2=80=9D and the missing =E2=80=9CResearch Logs.=E2=80=
=9D The logs, which contain the results of investigations into the =
various problems that occurred while attacking the Lorenz machine, seems =
to have disappeared at least it has been reported that they are not to =
be found at GCHQ. However, perhaps there is hope now that Professor John =
Ferris is supposed to turn the GCHQ archives up-side-down in his attempt =
to write the official history of GCHQ for its centenary in 2019. I wish =
him luck.

Best regards,
Frode Weierud
