Chapters names, POV, George RR Martin, Abraham

[Matheus]

Hi,
Do you guys know the origins of the type structure that George RR Martin, Daniel Abraham, James S.A. Corey (which is half Abraham) use in theirs book? By "structure" I mean the use of a third person POV with the POV's name being the name of the chapter.
I know those 2 writers work together, but I doubt that they "invented" this... So I would love to know where this came from.
Oh! And English is not my first language so this post probably has lot of errors, so I'm sorry! I’m used to read lot in English, but not write that much. :D
Thanks,
Matheus

Heinlein did this in Number of the Beast. All I can think of at the moment,

Thank you, Michele! Maybe when Tom and Veronica interview one of these authors again, they can ask then.
