THE secrets of the Enigma machine and Second World War code-breaking were revealed to members of the Rotary Club of Royston.

One of the surviving machines was on display - and members used the device to witness its intricacy.

Rotary club president Neil Heywood said: “This gave us the opportunity to appreciate the world of code-breaking in the Second World War and the ingenuity of such a machine.

“When the complexities of such a machine were explained it really showed the brilliance and dedication of those who were involved in code-breaking at the then secret establishment at Bletchley Park.

“We could see the reason behind it being said that unless the Enigma code was broken then the war could have gone on for at least another two years.”

The workings of the Enigma machine were explained to members by mathematician James Grimes, a member of the Cambridge University Millennium Mathematics project, which is working on supporting maths education and promoting mathematical skills.
