Oh please, it would've been extremely easy to title it "The Life of Einstein's First Wife, Mileva Marić," and thereby make it clearer she was a notable person in her own right, not for merely being Einstein's wife, to even a casual reader who didn't click through.
Well if you leave out her name, then readers will never see her as an individual and will only think of her as a wife of an important man. People on HN and even the author too will go into denial about this and give you some bullshit about "recognizability" or "editorialization" but that is the real reason because they both hate women and are also too cowardly to admit it.
