Dr. Deaton: It's rare, something that doesn't happen within a hundred years, but every once in a while a beta can become an alpha without having to steal or take their power. They call it a true alpha. It's one that rises purely on the strength of character, virtue, by sheer force of will.

This is word for word what Deaton says. The point of conflict is this: How literal do we take his words? Sure he says it "doesn't happen within a hundred years", so that would place the last True Alpha at 1913 or later, BUT the next line states that "every once in a while" it happens. If taken literally then Deaton's statement contradicts itself. Speculate what you will, I happen to think that he is merely using the hundred years as a "bench mark" of sorts.
