Napoléon Hayard

Born Napoléon Ferdinand Hayard in Remicourt, in the Marne, on December 16, 1850, he later became known as Léon Hayard. He worked as an editor, journalist, and political activist, and French reference sources describe him as a striking public personality in Paris at the end of the nineteenth century.

Hayard is closely associated with popular and political print culture. He wrote and published songs, pamphlets, and satirical pieces, and he became especially known for Dictionnaire d'argot-français, a lively reference work devoted to French slang. That book reflects the same world that shaped his public image: the streets, the press, and the quick-moving language of everyday urban life.

He died in Paris on August 29, 1903. Although not widely known today outside specialist readers, his work offers a vivid glimpse of popular speech and political humor in France during the Belle Époque.
