Sure, it doesn't spread down to 1901, but the uptick started around 1970s [1].

Anyway, my main rant was about the inefficiency of giving awards to "lone geniuses", at most three, of expecting said "lone wolves" to exist in the first place, and then comes the discussion if the wolves are male or not. Unfortunately it got derailed into talking about pseudoscientific scalars such as IQ and sex binaries.
