Yep.From replies: >This isn't exactly what you were asking for, but Littlewood himself, after overcoming depression at age 72, did good mathematics throughout his 80's--it's hardly a young man's game. (Littlewood is Hardy's pen name)

Of course that's not really true. The origin of the story is that so many papers were published by Hardy and Littlewood, that an Indian mathematician thought that Littlewood was a pseudonym that Hardy used for his inferior work. Littlewood was reported to be quite amused when he heard this. And of course the story might be apocryphal. Especially since it's also attributed to Edmund Landau and Norbert Wiener. https://en.wikipedia.org/wiki/John_Edensor_Littlewood https://en.wikipedia.org/wiki/John_Edensor_Littlewood

  That is, that either Landau or Wiener believed this, which seems very unlikely.
