From Gertrude Stein on Picasso, 1970, Liveright, 1946, Random House:

Then again in 1904 he was once again in Paris.

He lived in Montmartre, in the rue Ravignan, its name has been changed now, but the last time I was there it still had its old charm, the little square was just as it was the first time I saw it, a carpenter was working in a corner, the children were there, the houses were all about the same as they had been, the old atelier where all of them had lived was still standing, perhaps since then, for it is two or three years that I was there last, perhaps now they have commenced to tear it down and build another building. It is normal to build new buildings but all the same one does not like anything to change, and the rue Ravignan of that time was really something, it was the rue Ravignan and it was there that many things that were important in the history of twentieth century art happened.
