A first rate biography should include a good description of the important achievements of the subject, give a good sense of the subject's personality, provide the appropriate historic context in which to view the subject, be well written, and have good documentation. Westfall's biography of Newton is first-rate in all these dimensions. Newton is arguably the most important person in modern history. His work inaugurates both modern mathematics and modern physics. His achievements as a physicist set the pattern not only for physics but also for the other natural sciences. Newton's impact in larger culture extended also beyond the world of sciences. The historian of religion George Marsden wrote that Newton was the most important individual in the founding of the 18th century Enlightenment. Though Newton cannot be considered a member of that movement, his example of demonstrating universal natural laws understandable by human reason was immensely influential in European intellectual culture.

Westfall provides a detailed chronological account of Newton's life that covers all his major (and minor) achievements and is simply excellent at integrating the relevant historical background information. As Westfall writes, we regard Newton as a scientist and the emphasis in on Newton's career as a working scientist and mathematician. But, this is described very clearly within the context of late 17th century Europe. Westfall, for example, devotes ample pages to Newton's study of alchemy and theology. Since Newton spent a large fraction of his life working in these areas, it would be imposing an anachronistic perspective to minimize attention to these topics. Westfall is excellent at describing both the intellectual and social milieu in which Newton functioned. The sections detailing the history of mathematics and physics of Newton's important predecessors and contemporaries are first-rate, particularly his analysis of the impact of Descartes analytical geometry and mechanistic philosophy. His descriptions of 17th century Cambridge, with its concentration of pseudo-academic placemen, and of the generally patronage driven world of Caroline Britain are excellent. Never at Rest provides a vivid impression of the nature of scientific work in Newton's time. Westfall does not shirk from presenting complex mathematical and physical topics. These sections are tough going for those who don't recall a lot of math and physics but very worthwhile because they give an excellent sense of Newton's transforming effects on these disciplines.

Westfall delineates Newton's difficult personality very well and is fair in dealing with the numerous conflicts in which Newton became enmeshed, particularly the famous priority dispute with Leibnitz. Some of Newton's behavior is shown also to have stemmed from unexpected sources. Newton's theological researches led him to the conclusion that much accepted Christian theology is wrong and he had to conceal his Arianism and anti-Trinitarianism for much of his life. Some of Newton's achievements are shown as stemming from unexpected sources also. Westfall shows that Newton's alchemical researches, with their rather mystical element, probably contributed to freeing him from dogmatic mechanistic philosophy and facilitated his development of the idea of a universal, intrinsic gravitational force.

Newton is a fascinating figure and this biography will remain the standard for the foreseeable future.

I just finished Westfall's biography of Sir Isaac Newton. The man was way more amazing than I ever expected. For myself, being neither a mathematician nor a physicist, the most fascinating and surprising thing was his in depth and, for the time, out of the box examination of religion.

As with his scientific studies, Newton's religious studies were relentless in the pursuit of Truth. Between the end of the Bible and the nineteen century, I can find no one who concluded more precisely such doctrines as the nature of God, the relationship of the Father and Son, the relationship of God and man, the nature of early Christianity, or the magnitude and meaning of the then extant departure of Christianity from the original. Obviously, this is from an observer who agrees with his conclusions.

Newton's prodigious talent for leaving no stone unturned in his examination of his subject matter, coupled with his utter genius leaves me entirely in awe.

Westfall's 20 year effort in writing this biography has yielded a masterpiece!

Little can be added to the life of Sir Issac Newtons but what can be more clearly described as in this biography is Newtons moments of reasons with his numerous precarious situations. For example Newtons life long feud with the imbecile Robert Hook their is a newton letter quoted early in this relationship. Newton was trying to befriended and appeased Hooke with the comment " If I have seen further than others it is because I have stood on the shoulders of Giants". This reference to giants was a complement to the fair work of Robert Hooke who was at the time President of the Royal Society of Science. Soon this relationship again deteriorated and they became arch enemies for the remainder of their lives. Westfall captures these glistening moments better than the other five magor biographies of Newton I have read. Being a urologist it fills me with grief that Newton died of a severe Prostate obstruction and infection. Which I assume was not uncommon for those elderly men of the early 18th century.

This is a remarkable biography because it so thoroughly tells the story of Sir Isaac Newton in all its various aspects. Newton's determination to know, his science (breathtaking science, his awesome brilliance), the religious and alchemical investigations, the cranky aloofness, are all carefully and fully drawn; by the end of the book, you feel, along with the author, that you have got to know the subject (at least to the extent one might get to know the great man).
This is a great biography, because it is so detailed, so in depth and so successful at bringing Newton in view. It is also likely that it will for many years surpass any other biography of Newton because of its thoroughness.
I think it is worth reading not only because the reader learns so much about the science and life of one of history's great thinkers, and to some extent how he thought, but also because the reader gains an appreciation of the hard work of invention even for one so gifted as Newton, and some insight into the hard work of turning observations into theoretical constructs.
A magnificent biography.

There are a fair number of Newton biographies, this one is the most comprehensive and thorough, with a full treatment of the development of Newton's scientific and mathematical thought. What is remarkable is how rapidly Newton mastered the essentials of the techniques of his contemporaries, quietly reaching the forefront of knowledge, this in a few years, and without much prior training before his arrival in the world of Cambridge, where he flowered at once despite the almost defunct educational status of this university. The myth, however, of the annus mirabilis needs replacement with the reality of the anni mirabili, next to the near abandonment of mathematics for some years as Newton's concerns passed to encompass something broader than pure physics and his deskdrawer 'calculus' still embedded in geometrical formalisms. The final composition of the Principia in the wake of the coaxing forth of De Motu is grounds for thunderous applause for Halley who had the presence of mind to grasp who he was dealing with and the politic manner needed to communicate/negotiate with the reclusive prime mover of theory. His great work complete Newton is off to rescue the coinage at the Royal Mint,thence to the forgettable episodes of the priority quarrel with Leibniz. This work is slow but superb on all aspects of Newton's life.

This is the most authorative biograghy of Newton, the greatest genius of all time!! No need to add more words to praise him. Though the book runs over 900 pages, you would be reading the book breathless until the last page!!! ( similar view from other readers. )

This is in the same class as Ray Monk's Wittgenstein biography or Martin Gilbert's Churchill.

I couldn't put it down until I was at the back page, many dozens of hours after I began!

It left me exhausted but enriched!

This sets a standard by which the modern science biography should be judged.

Westfall says something to the effect that the more you know about a person, the closer you get to them, but in Newton's case, the more we learn, the more mysterious he becomes.

You won't be disappointed.

This book is a detailed and wide ranging biography of Isaac Newton. Though long (908 pages), the writing is crisp and precise. There is sufficient detail here that justifies the subject. Isaac Newton was arguably the greatest mathematician that ever lived except perhaps for Mersene. Every aspect of Newton's life is described in good detail. There is enough mathematics here to justify the biographical needs and to interest the reader to explore further. If you wish to get more of Newton's mathematics I recommend his Principia which is still a good read.

All in all this book is excellent. The nature and scope of the subject matter demands that the book be long. But the time and effort spent will be richly rewarded.

A comprehensive yet clearly written biography spanning every facet of the life of one of the worlds true geniuses. Compelling from beginning to end this book combines extensive research with a passion to provide an insight into both the work and personal life of Newton. Whilst other work may need to be consulted by the most mathematically minded, readers with a yearning for an insight into Newton's discoveries will generally be pleased at the detail provided. My only critism would be that this very large tome came to an end. Purchasers should be aware that at over 900 pages the paperback version of this book will require careful treatment if it is to survive.
