active 16th century Louis Meigret

Born in Lyon around 1510, Louis Meigret (also spelled Maigret) was a French grammarian, humanist, and translator. He is best known for Le tretté de la grammere françoeze (1550), a work regularly described as the first grammar of French written in French.

Meigret took an active part in Renaissance debates about the French language. His writings argued for spelling reform and a closer link between writing and pronunciation, making him an important figure in the history of French orthography as well as grammar.

Sources consulted agree on his importance, but differ slightly on dates; he is generally placed in the first half of the 16th century, with death given around or after 1558–1560. I couldn’t confirm a reliable modern portrait image of him, so none is included here.
