Mathesis: Recueil Mathématique was a Belgian scientific journal for elementary mathematics, established in 1881 by Paul Mansion and Joseph Jean Baptiste Neuberg.. See in particular p.20, which mentions the founding of Mathesis in the context of a brief biography of Paul Mansion.
An earlier Belgian mathematics journal, Nouvelle Correspondance Mathématique, was established in 1874 by Mansion and Neuberg together with Eugène Catalan. In 1880, Nouvelle Correspondance ceased publication, and Mansion and Neuberg together launched its successor, Mathesis, in 1881.. Mathesis ceased publication in 1915 because of the war in Europe, but restarted again under the editorship of Neuberg and Adolphe Mineur in 1922 as the official journal of the Belgian Mathematical Society, which itself was founded in 1921.A brief history of the Belgian Mathematical Society, Luc Lemaire, retrieved 2012-03-20.. It continued in publication until 1965.Worldcat catalog entry for Mathesis, retrieved 2012-03-20.
