TITLE: Original papers in algebraic topology
QUESTION [7 upvotes]: I am looking for the original papers in algebraic topology which primarily led to the development of what is found in many of the introductory
texts in algebraic topology: topics like homotopy and homology. Could anyone suggest such papers? My aim is to be aware of having a sense of how these topics developed and in what order and in the process also read some of the original papers. I hope it is not an unreasonable request. Thanks!

REPLY [5 votes]: I suggest you start with these books and the references they cite:

History of Topology,  edited by James.
History of Algebraic and Differential Topology, by Dieudonné.

A Brief, Subjective History of Homology and Homotopy Theory in This Century, by Peter Hilton.
