Summary: Disjoint and Superficial.The author had access to an outstanding group of individuals and in many cases squandered the opportunity with superficial questions. Instead of getting key insights, I felt like I was getting trivia. The interviews read more like something from People magazine (or maybe a sidebar in a Keyboard/Music magazine) than a highly rated book. Where is the depth that Kettlewell should be able to provide?I found it impossible to get through section two. The intent may have been to be exhaustive in its list of pioneers, but instead I found it exhausting - dry, dull, superficial and disjoint.In addition the book is poorly edited, as if rushed to publication.
