Talk:La Vallée Poussin

No hyphen
My copies of the two volumes of the course of calculus bear the name Charles de la Vallée Poussin. One may think that Charles himself, the publishers and prof. Fernand Simonart knew the spelling of the name. I would not use Vallée-Poussin without a good reason. I correct in the page. I do not know enough about changing the title of a page. --Dominique Meeùs (talk) 19:46, 1 April 2017 (UTC)

The page in French fr:Famille de La Vallée Poussin uses a hyphen for the 18th century painter only, and no hyphens afterwards. --Dominique Meeùs (talk) 20:00, 1 April 2017 (UTC)
