Most relevant literature on topology and modern geometry.

Question

I’ve been collecting and reading some articles and publications of history’s most influential mathematicians from different sources, so i’ve got a clear historical picture of their work, their contributions and the mathematical tools they developed in their respective fields. I want to do the same with topology and modern geometry, but i do not know where to start (please, do not refer me to pedagogical textbooks). I’ve got “the foundations of geometry” from D. Hilbert. and some publications from Riemann… but aside from that, i do not have much clue on what else should i search for. Maybe go back to cantor’s publications? Skip them with some more recent article that covers a more general range of the subject? Maybe Poincaré?
