I am fine-tuning a short note on basic category theory; any such course must introduce monads, and I want to give a bit of history of the subject.

I soon realized that I don't know the precise series of events that led Mac Lane to create the name "monad" (but it was him who coined the term, or he simply advertized it?) instead of the way less creative "triple" or "standard construction".

The only reference I can find is a broken link at the nLab page.
