TITLE: Who named it the Snake Lemma?
QUESTION [23 upvotes]: What is the history behind the colorful name of this result? Cartan-Eilenberg states it without any particular fanfare.

REPLY [2 votes]: If you Google for "diagramme du serpent" it becomes plausible that it was a diagram in Cartan-Eilenberg first of all, before a lemma. Interesting example of how Bourbaki became the standard grad student syllabus.
