Robert Olmstead, in France, reports that he has started a detailed illustrated Web timeline of Lovecraft in France.
He also has a clipping of an article from the Providence Evening Bulletin of 1970 that made Providence aware of the serious French reception of Lovecraft in translation…
Frank Belknap Long’s wife claimed in an interview that Jean Cocteau sponsored Lovecraft in France (presumably she meant he helped with the cost of the translations), and that was the main trigger for Lovecraft becoming more widely known again in America.
