So there's this person I know quite well whose career in auto racing is taking off in quite a big way, and his family has approached me about writing his biography. I've read a few biographies in my lifetime, but not many. I'm willing to take on the project, but I think I should get a feel for how these things are typically structured. I want to examine good writing in this context. I've tried searching for biographies that are well written, but I only get results for biographies about literary types. I don't want bios about writers, I want bios by great writers. Has anyone read any exceptional biographies they can recommend?
