SIR HERBERT SAMUEL LEON ( 11 February 1850 – 23 July 1926 ) was an English 
financier and Liberal Party politician, now best known a s the main figure 
in the development of the Bletchley Park estate in Buckinghamshire, which 
he had purchased in 1883. He was created 1st Baronet Leon of Bletchley in 

In 1938 the estate, including the mansion and some 58 acres, was acquired 
from the 2nd Baronet, Sir George Edward Leon, by Admiral Sir Hugh 
Sinclair. Sinclair, head of the Secret Intelligence Service, showed great 
foresight in selecting what may have seemed to the casual observer an 
unlikely site ‘for use in the event of war’. Shrouded in total secrecy 
during 1939-45 and for decades thereafter, Bletchley’s immense 
contributions to the Allied war effort continue to be researched, analysed

Codebreaking drama "The Imitation Game", starring Benedict Cumberbatch, is 
to receive its European premiere at this year's BFI London Film Festival.

The film sees the Sherlock actor star as Alan Turing - the British 
computing pioneer who cracked the German Enigma codes during World War II.

Keira Knightley also stars as Turing's close friend and fellow 
code-breaker Joan Clarke.

The film will open the festival on 8 October at the Odeon Leicester 

Cumberbatch, Knightley and director Morten Tyldum are expected to attend

"Enigma B207 - Hitler's Cipher Machine ?" article

I've noticed that in the current issue of the "Eye Spy" magazine ( No. 91, 
2014 ) there is an article "Letter from Fort Meade" by David Hamer,
regarding the "Enigma B207 - Hitler's Cipher Machine ?" ( pp. 68-70 )

This follows very much the description given in the article "Railway
Enigma and Other Special Machines", dated 30 May 2013, and available
here :

I wonder whether David or Frode Weierud have any new information on this
series of Enigma B2xx machines, which they could share with us ?

Just interested....(-;

British intelligence may rediscover its founding purpose
Any German espionage against Britain would summon memories of old battles 
- which London won hands down
By David Blair
The possibility that Germany may resume counter-espionage operations 
against Britain should inspire nostalgia rather than indignation. This, 
after all, is how the story began : just over a century ago Britain 
created a “Secret Service Bureau” with the sole purpose of taking on

Bletchley Park 'secret' codebreakers : Hundreds more named

honour includes testimony from Bombe operators

Hundreds more people have admitted they, or their relatives, worked at the 
home of the World War Two codebreakers.

The Bletchley Park Trust set up a "roll of honour" last October, including 
details of about 10,000 veterans, but asked for more to come forward.

The trust said some former Government Code and Cypher School workers had 
been "apprehensive" but most were "delighted" to talk.

Nearly 500 more names have been added to the roll since October's appeal.

Enigma : 75th Anniversary of GC&CS trip to Poland

July 2014

75th Anniversary of GC&CS trip to Poland 

The history of Polish contribution to World War II is generally known. 
However, relatively little is known about the Polish role in the "battle 
for secrets", i.e. in the reconstruction of the "Enigma", a German cipher 
machine, and in the development of apparatus that allowed the decryption 
of the code that was changed by the Germans on a daily basis...../snip/

Nazi book full of Enigma codes sold for £87,000 : 1944 version was soluble 
so it could be destroyed in case of capture

By Paul Donnelley

A book containing top secret Enigma codes that helped Nazi U-boats evade 
attack from the Allies has sold for almost £90,000.

Thousands of copies of the book were issued to the crews of the German 
submarines during the Second World War. But they were soluble and designed 
to be destroyed by throwing them in the water in the event of

Computer passes 'Turing Test' for the first time after convincing users it 
is human

A "super computer" has duped humans into thinking it is a 13-year-old boy, 
becoming the first machine to pass the ''iconic'' Turing Test, experts say

By Hannah Furness, and agencies

A "super computer" has duped humans into thinking it is a 13-year-old boy 
to become the first machine to pass the ''iconic'' Turing Test, experts 
have said.

Five machines were tested at the Royal Society in central London to see if 
they could fool people into thinking they were humans during text-based 

The test was devised in 1950 by computer science pioneer and Second World 
War codebreaker Alan Turing, who said that if a machine was 
indistinguishable from a human, then it was "thinking".

No computer had ever previously passed the Turing Test, which requires 30 
per cent of human interrogators to be duped during a series of five-minute 
keyboard conversations, organisers from the University of Reading said.

But "Eugene Goostman", a computer programme developed to simulate a 
13-year-old boy, managed to convince 33 per cent of the judges that it was 
human, the university said...../snip/
