Bill Tutte Codebreaker

Tom Williams

Description

BILL TUTTE CODEBREAKER 'THE GREATEST INTELLECTUAL FEAT OF THE SECOND WORLD WAR.' a testimonial to Bill Tutte and his codebreaking discovery in 1942 at Bletchley Park. Bill Tutte was a young, gauche PhD student, yet his remarkable breakthrough and continuing endeavour against a German cipher machine more complex than Enigma led to the development of the world's first programmable computer, Colossus. Colossus allowed top-secret messages between Hitler and his generals to be read within hours, contributing significantly to the success of the D-Day landings and the eventual defeat of Nazi Germany. So secret were the functions performed by Colossus that the work of Bill Tutte and his colleagues was classified for more than 50 years after the end of the Second World War. This novel not only explores Bill Tutte's codebreaking, but also examines his 'autistic' character, his background and close relationships all woven into the pressures and diversions of life at Bletchley Park. Prime Minister David Cameron wrote in 2012: We should never forget how lucky we were to have men like William 'Bill' Tutte in our darkest hour and the extent to which their work not only helped protect Britain itself but also shorten the war by an estimated two years, saving countless lives. I can say without doubt that Bill Tutte deserves the thanks of the British people.

About The Book
Bill Tutte Codebreaker
‘The greatest intellectual feat of the Second World War.’
… a testimonial to Bill Tutte and his codebreaking discovery in 1942 at Bletchley Park.
Bill Tutte was a young, gauche PhD student, yet his remarkable breakthrough and continuing endeavour against a German cipher machine more complex than Enigma led to the development of the world’s first programmable computer, Colossus. Colossus allowed top-secret messages between Hitler and his generals to be read within hours, contributing significantly to the success of the D-Day landings and the eventual defeat of Nazi Germany.
So secret were the functions performed by Colossus that the work of Bill Tutte and his colleagues was classified for more than 50 years after the end of the Second World War.
This novel not only explores Bill Tutte’s codebreaking, but also examines his ‘autistic’ character, his background and close relationships all woven into the pressures and diversions of life at Bletchley Park.
Prime Minister David Cameron wrote in 2012:
We should never forget how lucky we were to have men like William ‘Bill’ Tutte in our darkest hour and the extent to which their work not only helped protect Britain itself but also shorten the war by an estimated two years, saving countless lives. … I can say without doubt that Bill Tutte deserves the thanks of the British people.
Dedication
To the memory of Bill Tutte
and
all who contributed to breaking the German code that
Bletchley Park called ‘Tunny’.

Acknowledgements
Principal acknowledgements must go to Richard and Susanne Youlden, the great-nephew and great-niece of Bill Tutte. Their support, help and guidance has been immensely important to me without which, the book could not have been written. I am truly grateful to them for their trust and for granting me the opportunity to join with them and others in seeking appropriate recognition for their great-uncle. Very sadly, Richard Youlden died in April 2019, before this book was published. I am also grateful to Helen May Williams (no relation) for sharing with me and allowing me to use extracts from her mother’s wartime diaries and memoirs in the portrayal of the character Grace. Her mother was a graduate recruit to Hut 6 at Bletchley Park and interestingly, even her personal diary entries of that time held true to her vow of total secrecy. Helen’s mother was a wordsmith and poet and Helen, also a poet, kindly penned two poems for me in her mother’s style, a lovely counter-balance to the serious themes of the book. I must also express my heartfelt thanks to Helen for willingly employing her considerable expertise in reviewing, editing and suggesting improvements to my manuscript. There are many others who have contributed in various ways, too many to thank individually. I would, however, single out three. Firstly, I mention Jim Reeds, a distinguished American mathematician and cryptography historian, who is one of the editors of a significant academic work, Breaking Teleprinter Ciphers at Bletchley Park , which incorporates the 500-page General Report on Tunny (GRT). The GRT was compiled by key players at Bletchley Park over several months at the end of the war in 1945 but was only declassified in the year 2000. I used it a great deal in the writing of this book. On occasions, I consulted Jim Reeds, who willingly shared his considerable knowledge and expertise on the subject. I am indebted, too, to Frederica Freer, who, on my behalf, posed questions to her husband, Stephen Freer, on his association with Bill Tutte at Bletchley Park. Their ready responses were both most helpful and encouraging. Sadly, Stephen Freer died in April 2017. Lastly, I offer my thanks to Ken Halton for his time and conversation. Ken was a young GPO teleprinter engineer in the Newmanry at Bletchley Park in the final 12 months of the war. He took a great interest in Tunny and in his later years, contributed to a number of books on the subject. His entertaining reminiscences provided me with many ‘nuggets’ of everyday life at Bletchley Park.

A Foreword by Richard Youlden, Bill Tutte’s Great Nephew
At the corner of the sofa, his nose buried in a book, sat Uncle Bill: he rarely spoke, but saw everything going on around him. His silent presence easily dominated. When he did say something, his voice was soft and thin, surprisingly so. Occasionally, if he wished to be heard, he would affect an amusing gruff booming tone: a voice which growled for attention; a voice which as children we teased him to do for us—it was so odd and funny.
It was only years later that we discovered this was his lecture voice . I simply can’t imagine the shock awaiting students who met him back stage. Our great uncle was shy and unassuming, but he had a wicked dry sense of humour and wry wit. Every utterance was considered; Uncle Bill never wasted words.
Tall, with tousled white hair, he moved slowly like a stork: deliberate and reserved. He favoured shorts and t-shirt during the summer, but sported a Macintosh-style raincoat for those less clement moments. In the winter, his heavier coat was sometimes combined with a tea cosy style wool hat pulled down over his ears.
Uncle Bill and Aunt Dorothy came over from Canada and stayed with us periodically through our childhood: a wonderful, exciting pause from the mundane, filled with adventure. These were times when we would visit local attractions, play games and have far more fun than usual. Their visits often coincided with Christmas when we were small.
I recall laughing along with my brother and sister as Uncle Bill bounced us, all 3 together, on his knees, untunefully singing: ‘The Little Old Lady Who Swallowed a Fly’… doing all the appropriate sounds as he chortled through the tune. Uncle Bill was a big happy child at heart. Aunt Dorothy loved that here ‘Billy’ could leave his work behind for a time and truly relax.
Aunt Dorothy, with her serene nature and soft Canadian drawl, was in many ways the antithesis of Uncle Bill. Lively and outward-going, she seemed to talk from the moment they arrived. Uncle Bill lingered patiently in the background, lost amid his thoughts…
As we grew, the visits were less frequent but just as magical. Our only true family holiday was a week staying with Uncle Bill and Aunt Dorothy in an Oxford town house—a property belonging to the college where Uncle Bill was teaching. We played Monopoly, we enjoyed a coach tour and explored the city, watching the boats on the Isis.
In the mid-90s, I had the great pleasure of attending the switching on of the Colossus re-build with Uncle Bill. We sat in a small courtyard eating lunch; it was a glorious sunny day. I took this opportunity to ask Uncle Bill about Bletchley. In reply to most of my questions, he smiled to himself, and hesitantly replied,
