フランソワ＝ルネ・ド・シャトーブリアン
Guéranger was born in Sablé on 4 April 1805 into a working-class family. As a young boy, he frequently read "The Genius of Christianity", a work written by François-René de Chateaubriand which defended the Catholic faith against the claims of the Enlightenment, and which had been published shortly before his birth.
