How far back in Boxings history can you find a Pound for Pound list?

I may be wrong, but I think I may have read something years ago that talked about the term being used for Joe Gans. As far as printed lists I believe you're correct though, at least to the best of my knowledge.

I think that could be right.

I was just using Canzoneri as one example.
