I am a man who did his PhD in the 2000's. If my supervisor took my data and went on publishing them under his name, not only would I have kicked him in the ass publicly, but I would make my personal vendetta to crap his academic life.
She was a woman (with a not-so-nice character), in the 50s, so this would not have flown, obviously.
Let's not pretend he was not a crappy person in the name of a virgin academic world.
