This book is fatally marred by Dyson's failure to understand computer architecture. I note many reviewers assuming that they are confused because they are math phobic. But I was a programmer in the late 1970s and 1980s. I wrote in Assembly language and have read machine language (in hex) when debugging, so when I read Dyson's long passages of gibberish purporting to describe what is going on in a computer I knew they were just plain gibberish.

The stories about the people involved in the project

A fascinating and illuminating book, but also a frustrating one because it should have been a lot better than it is.

The heart of the story is more or less on target – a collection of very interesting anecdotes and narratives about the personalities involved in building America's first computer, at Princeton's Institute for Advanced Study after the Second World War. Leading the team was the quite extraordinary figure of John von Neumann, about whom I knew rather little before reading this. He com

I might have easily given this book four stars if Dyson could have stuck to history instead of indulging himself in inane speculations, and commentaries that are sadly meant to sound profound. The connections he draws between completely unrelated aspects of technology and biology are so strained that whenever I read a particularly grievous one, I'm forced to put the book down and walk around the room until the waves of stupidity subside a bit. For example, at one point Dyson asks us to consider ...more
If you are looking for information about Alan Turing, look elsewhere. The title is a metaphor.

The Nazis did the U.S. a huge favor with their boorish and stupid racial policies. Many prominent Jews were brilliant mathematicians and physicists, and when the “cleansing” of universities began by the Nazis, people like Van Neumann, Einstein, and many others fled to the United States where they were of immense assistance in the development of the atomic bomb.

This book covers essentially the same material as William Aspray's 1990 John von Neumann and the Origin of Modern Computing, the life and times of John von Neumann and the IAS computer. Aspray's book is much more to the point, though, while Dyson's takes large detours into the history of the atomic and hydrogen bomb, World War II cryptography and the like - all these topics have better books dedicated to them. George Dyson has a personal connection to the Institute of Advanced Study because his ...more
A history of the early computer and what miracles were done with it. The computer, says the author, is one of the great creative forces of the 20th century, compared to the great destructive force of the atom bomb - and certain instrumental figures worked on both.

The title appears to be misleading, as Mr. Turing himself only appears some 200 pages in. His contributions, although not immediately evident, are still quite important. The majority of the early part of the book concerns Princeton's In

Recommends it for: those interested in the history of numerical computation
Despite the title, this book is not primarily about Alan Turing. It is really about the group of people at the Institute of Advanced Studies at Princeton. Much of the book focuses on John von Neumann, who spearheaded the effort to build some of the earliest electronic computers. These first computers were very unreliable--incorrect results were as likely due to faulty vacuum tubes as coding errors. In fact, circuits had to be designed to be robust to vacuum tubes that did not follow specs.

This book started off rather confusingly--without a clear description of what it was to be about. It did not improve. For some reaosn,the author thought it very important to tell how Princeton was founded and had a lengthy chapter on William Penn from the 1600s. I thought it might be the format--I was reading on Kindle, and entertained the idea of getting the hard copy to flip through irrelevant sections. I then checked reviews and decided to give it a pass all together. Other folks have found i ...more

The history of the universal electronic computer at the Institute of Advanced Studies in Princeton, pioneered by the leading genius of his time, John von Neumann, and driven largely by the computational requirements of building a nuclear bomb, makes for a good book. George Dyson’s Turing’s Cathedral is not that book.

At his best, Dyson writes compelling, erudite, witty, and idiosyncratic prose with a gift for poetic analogies and elegant turns of phrase. The opening of chapter XVII, on the vast c

I'm fascinating by the history of computing. There are so many delights there, both geeky and otherwise: glimpses of our present, odd characters, brilliant technical solutions, politics. Turing's Cathedral is a delightful and useful contribution to this field.

George Dyson's book takes place during the 1940s and 1950s, focusing on the extraordinary collection of geniuses in Princeton's Institute for Advanced Study, and who created a huge amount of modern computing. A large part of Turing's Cathed

The IAS MANIAC project was indeed a truly revolutionary computing endeavor, and it deserves a well-written history. Unfortunately, you will not find it here. Dyson doesn't seem to understand most of the technical issues he tries to describe, and he often resorts to vague attempts at seemingly profound statements (see the end of almost every chapter for examples). Dyson is at his best when he describes the personalities of those who contributed to the project, but this doesn't really save the wor ...more

In several reviews, this book has been called a nerd's labor of love. Okay, but it is also exceptionally well written. The sentences are crafted to keep pulling one in to the action. This is not a direct timeline book, though. Dyson introduces the players as they enter the drama of advancing computing.

It is not bog down with old techno speak and specifications. Dyson sprinkles in the interesting facts just as needed. The massive 30 ton computers of the late 1940s did have over 17,000 vacuum tub

The title is a little misleading. This book is mostly a biography of John von Neumann and concurrently, a story of the early decades of the Institute for Advanced Study in Princeton. The stories are well researched and rich in detail, but at times hard to follow. I think this comes from abrupt changes in the timeline within related chapters. What comes across clearly is the value of interdisciplinary collaboration among genius level scientists and engineers in the presence of new electronic tool ...more

Turing's Cathedral is a long, enthusiastic and articulate ramble throughout the early history of computing, a solid work constructed over a great deal of time by a keen observer who has an insider's perspective on many of that history's most pivotal moments. George Dyson is the son of the famous physicist Freeman Dyson, and as a child he must have met many of the principals of this story while they were working at the Institute for Advanced Study (IAS) in Princeton, New Jersey (although at the t ...more

This is such a maddening book! Is it history? Is it biography? Is it science? Is it speculation? Well, that would be yes, yes, no and yes.

It’s not quite what I was expecting as it has little to say about Turing and his theories or the Colossus machine he is known for (although that’s my fault for not reading the blurbs). Rather it’s about the subsequent computer revolution that developed from it after WW2, and the ENIAC computer in particular.

But this book is not only about the mathematicians an
Mar 23, 2013 Jeff rated it liked it
I enjoyed reading this, and learned several new things while doing so. The book is not at all about Alan Turing. If it is a biography of anybody, it is John von Neuman; but really it is about many people, centered around the IAS in Princeton, who played a role in early computer development. There is also a lot of discussion about the development of nuclear and thermo-nuclear weapons, as one of the first applications of electronic computing.

Two big downsides prevent me from rating this book high

Though I would never dare to participate in anything but a cursory, general conversation about Turing machines or Gödel's theorem or the Monte Carlo method, I just love histories of science and this book made me happy. I listened to the audio version, and often arcane concepts requiring visualization or anything involving equations would blow past me, but all the wonderful details and biographies and momentum more than made up for my muddled moments. I love that it started with a disorienting-or ...more

A disappointment, mainly due to a lack of coherent organization. Dyson assembles a great deal of information, anecdote, and explanation -- some of it fascinating and engaging, but not all of it lucid -- without providing the necessary connecting tissue. The reader is left to do the author's work. This baggy enterprise made me go back to a book by Steve Heims called JOHN VON NEUMANN & NORBERT WIENER: From Mathematics to the Technologies of Life and Death, published some thirty years ago, now ...more

I keep this photo over my desk at work. I think it looks a bit like a microscopic close-up of a drop of milk, or maybe a bacterial colony. In fact it's a shot of the Trinity Test, the planet's first atomic detonation. To me, this event and the context surrounding it are the most fascinating and amazing chapter in all of human engineering: in a panicked fight against evil, a collection of human intelligence was assembled that, through sheer intellectual might, wielded abstract mathematics and app ...more

Turing's Cathedral: The Origins of the Digital Universe by George Dyson

"Turing's Cathedral" is the uninspiring and rather dry book about the origins of the digital universe. With a title like, "Turing's Cathedral" I was expecting a riveting account about the heroic acts of Alan Turing the father of modern computer science and whose work was instrumental in breaking the wartime Enigma codes. Instead, I get a solid albeit "research-feeling" book about John von Neumann's project to construct Turing

I have no idea why people claim this book is so bad. I agree the narration is non-linear, and possibly confusing, but it doesn't deserve all this flak.

I'm not sure if these ranting people understand the concept of non-linear story-telling. There are people who said "I'm not so technical, but..." and some are ready to burn the book for not explaining von Neumann architecture in detail. I remember the book mentioning the ability to store code and data in the same place (address space) -- I'm not s

This is the story of the making of the first computers. It is the story of the ideas, the machine, the math, the physics, the engineering, the people, the politics, and the physical and social environment. There were sections of the book that were over my head, but that was okay. In a page or two there would be a beautiful di

Ultimately, this is a very good book. The only thing keeping it from being a great book is the author's almost messianic fascination with the role cellular automata and its ilk played in the digital computing revolution, and the role the results of that revolution is playing in society.

I realize this might seem counterintuitive, but the religiosity that comes through in Dyson's meandering ruminations on the ramifications of the history he is recounting do not, in my opinion anyway, actually lend

I long anticipated reading "Turing's Cathedral". My adult life was spent working with computers and I still maintain a keen interest in all things computer related. The early days of computers is of particular interest so I anticipated this book being a great read. However, after reading 100 pages I decided life is too short; I’ll be returning the book to the library tomorrow.

While there were several nuggets contained within those first 100 pages those nuggets do not make up for what I thought

Man, this book was a slog. The history of the concurrent development of digital computing and the atomic bomb program are Relevant To My Interest, but even that was strained at times on the author's insistence on detailing at length every bit of history or biography related to people and places in the book. Most of the development of the IAS computer, the focus of this book, takes place at Princeton. Is it really necessary to go back two hundred years and learn about the colonization of the town ...more

TURING’S CATHEDRAL. (2012). George Dyson. ****.
This is essentially a history of the Institute of Advanced Studies set up at Princeton, and of John von Neumann, the driving force behind its foundation and ultimate staffing. It was started during WW II, as an adjunct to the military’s effort to determine artillery trajectories using their fledgling computer. Princeton’s computer, however, was put to a diferent task – the development of the H-bomb. This was accomplished using their fledgling compu

Fascinating book. It is much needed social history / genealogy of computing based on IAS in Princeton. Yet, it is the social history bit that really attracted me to the book and that absolutely shines through. In some ways it's almost a real-life sequel to something like von Rezzori novel. The cast of all these odd and stray Mitteleuropa scientists is just fascinating.

It's just as fascinating to read about the very early computers and discover all these small design decisions that end up having
