, describing her as a very reserved person (
collection of Archives Anarchistes) Marie Françoise Monnin was born on 29 February 1852 in the 4th arrondissement of Lyon. The daughter of Julie Bouton and Claude Monnin, a canut, she also had a sister, Virginie, who later married the anarchist
Claude Bernard. Her mother remarried, taking the name Madignier in her second marriage.—and the same day as the sentencing of
companions Claude Crestin and Auguste Bonthoux for some of their writings, she attended a meeting held by the Federation. The group, which according to police reports consisted of two men and one woman, remained in the building for a time before leaving their booth and the premises. 200 people were still inside when three explosions happened in the building. The attack injured about ten people, four of them seriously. Unlike the attacks by the Black Band or the
bombing of the Thiers statue, this attack was lethal: one of the seriously injured victims died four days later. Meanwhile, Madignier—who was becoming a suspect in the attack as she matched the description of the primary suspect and was summoned to appear before the investigating judge—disappeared, likely fleeing to Switzerland. She reportedly wrote from there five days later, in early November 1882, to request financial aid from her Lyon companions, who allegedly sent her 10
francs. This remains the last known record of her life. Two years later, in December 1884, Madignier was
sentenced in absentia to life imprisonment in a penal colony for the bombing. == Primary sources ==
