When I read Linus Pauling and the Chemistry of Life, I said it was the best biography of his. I didn't know that the same author wrote even a better one. In fact Linus Pauling and the Chemistry of Life is more like a summary of this book (700 pages vs. 140 pages).
Tom Hager did a really good job in explaining Pauling's contributions to chemistry and medicine. He was a man full of ideas and a will to try to execute them. A career full of success.
