If you love books about audacius, bad assed business men, then read this one. Mellon was a VC. The two unicorns he backed were Alcoa Aluminum and Gulf Oil. And oh, a small bank that beared his name.
His Scotch Irish decent served him well until the Great Depression hit. Then his Scotch Irish decent failed him miserably because he couldnt accept the thought of deliberately expanding the money supply. As Treasury Secretary he was the guiding hand for Hoover and Mellon couldnt see the forest for the trees. His immense wealth kept him from understanding what the market actually needed.
Very good economic lessons from this book. Stuff they dont teach you at HBS.
