François est placé chez Jean* et Joséphine Gaultier*. À la ferme, l'enfant juif fait partie de la famille. Il suit Yvonne partout. Assis sur le porte-bagages, ils vont au cinéma à Pouancé à vélo. Il tente de vivre l'insouciance des enfants de son âge.
À l'école, François est le Parigot. Voire, parfois, le Petit juif.
Jean* et Joséphine Gaultier* cacheront également durant quelques semaines un soldat allemand déserteur dans leur grenier.
À la fin de la guerre, les enfants retrouveront leur père Raoul, qui a échappé à la mort.
Jean and Joséphine Gaultier were Catholic farmers who lived near Pouancé (département of Maine-et-Loire), where the Jewish rescue organization OSE had placed several Jewish children in hiding. Among them were the two Rosenthal brothers, who were staying with a foster family that owned a café in the village. Every evening the two boys came to the Gaultiers’s farm to buy milk. They were from Paris. Their father had been arrested and deported to Auschwitz, and his widow died later, leaving four children. Two of them were sent to Pouance. François Rosenthal, who was eleven, told the Gaultiers that he was suffering in his hiding place and feared the German soldiers, who frequented the café. He begged the Gaultiers to let him move in with them, and after they accepted, he spent the next three years with them. The Gaultiers had three grown children, Marie, Yvonne, and Jean, and treated François as one of their own. Indeed, when the German soldiers asked questions during their frequent visits to the farm, the Gaultiers responded that Rosenthal was their youngest son. His brother, who was also hiding in the village, visited him regularly. Because he was afraid to attend school, François stayed at the farm. The Gaultiers knew that they were taking an enormous risk by harboring a Jew and did so without the slightest remuneration. After the war, Rosenthal’s father, one of the few who survived Auschwitz, came to reclaim his son.
On March 27, 1996, Yad Vashem recognized Jean and Joséphine Gaultier as Righteous Among the Nations.
