Petiot—Marcel in court
Definition A French doctor and serial killer (1897-1946) convicted of killing 26 people, who is thought to have killed up to 60 victims during his career before he was beheaded by French authorities in 1946, one of the last judicial uses of the guillotine.
Comment Petiot was diagnosed as mentally ill when he was 17, but that didn’t stop the French army from drafting him and sending him to the front lines in World War 1. He shot himself in the foot, deliberately, was discharged with a disability pension, and was accelerated through medical school (he received his medical degree with a mere 8 months of formal education). Afterwards, he earned a reputation for embezzlement, dishonesty, and unethical medical practices. Many of his wealthy clients disappeared.
