Query: Triumph and Tragedy

I learned more about structural engineering (and caissons!) then I'll ever care to know again. A structural engineer would love this book. I found it at times, to be tedious reading, but still a fascinating account of the bridge and more importantly the Roebling family who built it. Washington Roebling's life was like that of a Greek tragedy. I wish the Kindle version of this books and pictures and diagrams, but it did not, making me now want to get a hard copy of this book.
