5.0 out of 5 stars Valuable part of the wartime jigsaw
This book contains numerous articles written by some of those invisible people who actually took part in this top secret project. Some of the accounts are those of frustration, from people not allowed to get the recognition that they and their colleagues deserve. The level of detail and understanding shown makes this a very interesting and unique picture. I would...

3.0 out of 5 stars Colossus review
After a visit to Bletchley Park I was keen to delve further into the dark world of cryptography. As the title suggests this book concentrates on one of the final pieces of kit which speeded up no end the breaking and reading of German codes. I was with it all for the first two or three chapters but after that it was a struggle - a knowledge of advanced maths is a...

Quite mathematical coverage of Colossus and its role in cracking the German High Command Lorenz teleprinter coding machine. Very good

My 12 year old absolutely loves this book. He has learned so much from it, and as a matter of interest, has taught the rest of the family

This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
This is not the easiest book to read. The subject matter is complex and requires a lot of effort to understand what was achieved, but well worth the effort. The mind boggles at the intellectual brilliance of the people at BP and at the way in which the people concerned were identified and recruited.

5.0 out of 5 stars A well researched and presented book, 22 Aug 2013
Verified Purchase(What is this?)
This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
An excellent and detailed account of the work by dedicated people to crack the German codes. Such a shame that it took so long for the history to become declassified, and so much of the original equipment and documentation destroyed. Take your time to read the book and understand the science of how the codes were created and then decoded. Also nice that we beat the Americans in creating the first truly electronic digital computer - despite what others may think.

This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
... I have other books on Station X and associated services, but this one really gets to grips with the mechanics of the problems faced. I suppose as more information comes to light then these things will continue to develop. However, as time moves on, what is becoming more difficult to include is novel first-hand experience of the war-time work done in computing and code-breaking.

3.0 out of 5 stars A very interesting history of Bletchley Park, 22 Jun 2013
Verified Purchase(What is this?)
A fascinating insight into the development of Colossus and related technology on the basis for code-breaking enemy messages. There are many unsung contributors from mathematicians and engineers, to armed forces personnel whose combined efforts contributed to British and American victory over the Nazis through ingenuity leading to specialised technology. A good book to dip into. For those less interested in the details of code-breaking, there is still significant insight to the people and culture of the time. It's a great shame that the Kindle version of this book omits the photographs which are a significant adjunct to the stories.

This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
Lovely rambling anecodotal style telling a fasciniting story and gives added insight to recent Turing biography. Visits to the computer museum at Bletchley Park are always a joy - especially the entusiatic staff!

This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
I bought this on the Kindle for myself andd then as a birthday present on paper for my brother-in-law. We both liked the book very much.

The book has chapters written by different authors most whom were involved in the work at Bletchley. It includes a chapter by Tommy Flowers which reveals how cross he was that his work appeared to wasted after the war. In fact it was not ut he did not know that and surely his talent deserved better use than repairing telephone exchanges. It also includes a chapter by Roy Jenkins on his work at Bletchley which is fascinating.

It also has a full technical description of Colossus and an accessible discussion of the mathematics that underpinned Colossus.

All in all this is an essential book for anyone wanting to understand the work at Bletchley or the early history of computers.

This review is from: Colossus: The secrets of Bletchley Park's code-breaking computers (Paperback)
Written by various contributors, some chapters are easier for the layman to read than others. If you want to know details of mathematical problem solving this is the book for you, but if you have a general interest there are other, more readable books.
