Patornay, Leonard a French Jesuit, was born in Salins in 1569. He joined the Jesuits at the age of seventeen, and for several years taught theology and the Holy Scriptures in different houses of his order. A skillful controvertist, he opposed the Lutheran heresy, and cardinal Richelieu, who esteemed his talent, several times employed him to reply to the ministers of the Reformed doctrine. Patornay died at Besancon in 1639. He published, under a fictitious name, Declarationes aliquce multorum deductorum ad Ecclesice casira. See Backer, Biblioth. des Ecriv. de la Comp. de Jesus, s.v.
