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.

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
