Query: Amazing story of the Palomar telescope and the man behind it

I bought my copy at the gift shop at the Palomar Observatory! I read the book over the next week, almost unable to put it down. The book covers much about Hale, the man behind the telescope and several earlier "largest telescope in the world" projects. He battled many private demons to get his dreams built. The book covers the processes in construction and use in a lot of detail, with a lot of drama (there were many points when all could have been lost very easily). Anyone with an interest in astronomy, the history of technology, or the history of science would enjoy this book.
