I thoroughly enjoyed this book and found it well written and informative. The account of Brunel's life is mostly chronological, except where chapters are devoted to big projects, such as the building of the SS Great Eastern. It is clear that the author has a great respect for this enormously talented and gifted engineer. However, Vaughan does not flinch from showing Brunel's darker character traits but sometimes I feel these are imposed too strongly. I often got the impression that all fault seemed to lie on Isambard's side, whereas the other participants were portrayed as intimidated, unresponding victims. In fairness Vaughan does point out that in his researches he found many letters written by Brunel but very few letters that were received by him, thus the author had to give the other side a benefit of doubt. It is also acknowledged that towards the end of his life Brunel was very ill and still taking on enormous workloads that could not possibly have helped his temperament. IKB's many engineering achievements are documented but there is little technical detail, as one would expect with a book that is dedicated to Isambard's character and the forces that drove him. The most pleasant aspect of reading this biography was that a man who has been a hero of mine for many years still remained a hero at the close of the final chapter. In conclusion a worthy and balanced testament to the life of a great man and a book I would not hesitate to recommend.
