I'm not sure why you're being downvoted, thanks for the link, I've bookmarked it for later reading. Was that short bio 'La Clef des Songes,' I heard it was translated into Spanish, but never looked to deep for it.
People really should be forced to refute before they can downvote. Even if you disagree with his points, he gives substance for what and why he said what he did.
The short biography was "The Artist and the Mathematician: The Story of Nicolas Bourbaki, the Genius Mathematician Who Never Existed" [0]. It dedicates a good chunk of the book to the life of Grothendieck. Grothendieck was a member of the group that used the Nicolas Bourbaki pseudonym. It's a fun read you can finish in an afternoon. Not sure how accurate it is.
