In the summer of 1999, I was an approached by an intermediary at the WSJ about whether I'd be interested in profiling a banker who was at the top of the red-hot world of dot-com IPOs. Of course I agreed, and for the next decade I worked off-and-on on stories --and a book -- about the banker, Frank Quattrone, and the voluminous regulatory fallout from his two years at the center of what had proven to be the dot-com bubble. Although many of his IPOs had crashed and burned, one of them, Amazon.com, became a spectacular business success over next 20 years.
