His great-grandfather, Joseph Chatranet, a native of Dijon, had settled in Provence under King Charles IX of France and taken the name of the village of Moréri, which he acquired through marriage.

[1] Louis Moréri studied humanities in Draguignan and later rhetoric and philosophy at the Jesuit College of Aix-en-Provence.

[2] In 1675, shortly after publishing the first edition of his encyclopedia, Moréri accompanied his bishop to Paris, where he became acquainted with Simon Arnauld, Marquis de Pomponne, then the minister of foreign affairs.

[3] Moréri's encyclopedia, Le Grand Dictionaire historique, ou le mélange curieux de l'histoire sacrée et profane (literally, The Great Historical Dictionary, or Curious Anthology of Sacred and Secular History, although it was translated differently into English at the time) was first published in Lyon in 1674.

[4] Moréri's Grand Dictionaire historique gave rise to a more famous encyclopedia, Pierre Bayle's The Historical and Critical Dictionary (1697).
