Interesting and very expansive non-fiction about the various big naturalists throughout history (spoilers, they're mostly white men). Genuinely had me hooked from the start and I definitely learned a new thing or two. Some of these people I've already read about before, others were new to me. This book definitely broadened my horizons on natural history researchers a bit.

It's also richly illustrated and has a nice layout with each page having an old-paper-ish texture, almost like you're reading a real old non-fiction book about the subject.

If I do have one criticism it's that some people had longer chapters on them than others, which feels a bit unbalanced, but I'm not sure if this is because there is less known about some of them, or they made smaller/less contributions to the field or something like that.
