While thinking about how easily we assume a #halo effect stemming from success in a particular field (hi, Elon), I was reminded of the apocryphal story of #Newton creating a cat flap for his #cat and a smaller one for her kitten.

A quick search for more details revealed several sites providing chapter and verse on this and related myths (such as Newton actually inventing the cat flap), including the history of the story and the likely origins of it. Unfortunately, it also turned up hundreds more excitedly repeating the claim.
