Antoine Guillois was a French author and historian who lived from 1855 to 1913. Library and authority records confirm his dates and show a body of work centered on French history, especially the late eighteenth and early nineteenth centuries.
His books include studies such as Le salon de Madame Helvétius; Cabanis et les idéologues, La marquise de Condorcet, and Napoléon l'homme, le politique, l'orateur. Taken together, they suggest a writer drawn to the intellectual life of France as well as to major political figures, with a particular interest in biography, salons, and the world around the Revolution.
Detailed personal information about Guillois is hard to find in the sources available here, so it is safest to remember him mainly through his books. Those works show a historian interested not only in events, but also in the personalities, friendships, and conversations that shaped French public life.
