You could be excused if you came away from this believing that Frances Allen invented all of these optimizations.
She didn't.
With that cleared up, you might think that, at least, she is the sole author of the overview paper cited.
She isn't.
It seems an overwhelming need to come up with some heroic narrative around "women in coding" got the better of this author. I don't think this kind of "proof" is helpful.
