I was well aware that Schulz's family was very upset with the biography, although whether because of delibrate skewing of the material by Michaelis, or anger at seeing one's husband or father depicted in anything other than a hagiographic manner, I can't determine. But what I did find interesting was one of Monte Schulz's reactions to the book, as published on the "Cartoon Brew" web site:
But what about voices who weren’t heard? Well, for example, he only spoke to my sister Jill once over a lunch and that was that. He did interview Cathy Guisewite, but then called back to ask her, if you can believe it, whether or not my dad “came on to her.” Is he joking? Cathy knew Dad for more than twenty years, and except for one or two lines, David left her out of the book in favor of Lynn Johnston who provided much more provocative information, much of which (particularly in the first draft) is silly and self-serving.
Somehow, I'd sure love to know what was in that first draft...
