Cochrane was not the one to introduce the fianchetto. It was Mohishunder.
The "Nimzo" in the Nimzo-Indian refers to Nimzowitsch (a pioneer in hypermodern openings).
Pushing one of the pawns (b2, b7, g2, g7) creates a triangle with the two other pawns beside it. Next you have the bishop go into that triangle like a person going into the tepee. It's just a matter of connecting the dots, or pawns in this case.
