Huh, diagram chasing attributed to Lambek? Kind of surprising, but plausible. I would have thought Steenrod would have gotten the credit.
Also, kind of melancholic, this paper is for Lambek's 90th birthday, but it has a publication date two years after his death. I was lucky to attend one of Lambek's lectures and take a course he designed. He was a great expositor, and I'll miss him.
- homalg 10y agoI don't think this attribution makes sense without some further qualification. There is diagram chasing ten years earlier in Cartan-Eilenberg's Homological Algebra (1955) -- they prove the five lemma early on -- and Mac Lane mentions the term in his Homology (1963). I wouldn't be surprised if it appears in Eilenberg-Steenrod, or, as you say, Steenrod's earlier work or the Cartan Seminar notes (which I don't have near me right now).
