You probably haven’t heard of Antoine Berthet, but if you’ve read The Red and the Black (Le Rouge et le Noir) you know his story. Stendhal (a native of Grenoble) published his magnum opus not three years after Berthet lost his head, and the novel’s executed fictional protagonist Julien Sorel bears an unmistakable resemblance to the very real Berthet.
Berthet was a smart seminary student of low birth who hired out as a tutor for the Michoud family but was dismissed under a cloud for an apparent affair with Madame Michoud.
Nothing daunted, Berthet caught on as a tutor in another family — where he proceeded to seduce the lovely daughter Henriette. But a letter from Madame Michoud to the new employers terminated job and liaison alike.
The enraged Berthet stalked his former mistress to Mass and melodramatically shot her right there in the church. He failed to kill his target, and likewise failed his attempted suicide.
Unlike his literary doppleganger — the Julien Sorel character defiantly spurns his former lovers’ attempts to pull strings on his behalf and insists on his responsibility in court — Antoine Berthet mounted an unsuccessful insanity defense. It was the “irresistible derangements of love” drove him to outrage feminine virtue, consecrated grounds, and (maybe most scandalously) the upper classes.
His prosecutor disagreed, attributing all to Berthet’s frustrated “ambitious dreams”: “understanding too late that he could not reach the goal that his pride proposed, Berthet, stripped of his hopes, would perish; but his rage would drag a victim along with him to the tomb that he dug for himself!”
