The unknown heroes from Bletchley Park will get their moment of glory as a book focusing on the war has been released to the public.

‘100 People You Never Knew were at Bletchley Park’ showcases those who spent hours, days, weeks, months, and years attempting to crack the codes the Germans used during the Second World War.

The breaking of the codes played a pivotal part in the UK’s and USA’s victory in the six-year battle between 1939 and 1945.

This led to Italy falling under the dictatorship of Benito Mussolini and the collapse of Nazi Germany.

However, many of the codebreakers had to sign contracts, blocking them from sharing their important role in what is, to date, the biggest war in human history, with approximately 85 million fatalities.

The book came out at the end of 2021

Written by Sinclair McKay, the book profiles 100 Bletchley alumni from Roy Jenkins to Baroness Trumpington, but also chess masters, musicians, and naturalists, along with teachers, the woman who saved St Pancras Station, and the man who wrote the music for the Dracula films.

A spokesperson from the book said: “For many years, no-one knew anyone had been at Bletchley Park.

“Then 10,000 men and women who had worked at the wartime codebreaking centre had to sign the Official Secrets Act, and kept their vow implacably for decades, with their own families not knowing of the crucial work they’d done cracking the Enigma codes.

“Even the handful of individuals whose work at Bletchley Park made them household names turn out to have had unexpected hinterlands.

“For all of them, codebreaking was just one of their many extraordinary achievements.”

The book can be bought on Amazon, Waterstone’s, and other bookshops.
