Scanning through the comments, I'm noticing a bit of skepticism over the "legitimacy" of this work. To a large extent, that's probably fair: people have every right to be skeptical of anything calling itself a biography. The rigor of scholarship, access, and sourcing involved in writing a competent biography is a high hurdle to clear.

That said, the idea of Leanpub is to let authors write lean. Writing lean isn't an excuse for half-baked scholarship, but it is an opportunity to publish an "MVP" book and iterate from there. To me, that's what the author is trying to do here, and he should be applauded for that effort and gumption.

This is a huge undertaking, and for that reason alone, I'm intrigued. I wish the minimum price weren't as high as it is (probably another big blip on the skepticism radar), but I would love to check it out.
