Twelve days after the tragic deaths of Mathilde Favier and Nicolas Altmayer, who died together in a road accident on August 17, 2026, in Deux-Sèvres, their families announced the arrangements for their funerals. The two religious ceremonies will take place on Monday, August 31 , but in different formats. Mathilde Favier will be accompanied at a ceremony at the Church of Saint-Sulpice in Paris, while Nicolas Altmayer's funeral will be held privately.
Mathilde Favier: a ceremony at Saint-Sulpice at 14:30 pm
The funeral of Mathilde Favier , 57, will be held on Monday, August 31, at 14:30 p.m. at the Church of Saint-Sulpice in the 6th arrondissement of Paris . The announcement was made by her family: her children Héloïse and Carlo Agostinelli, their father and siblings, her mother, her sisters Victoire de Castellane and Pauline Hénin, and her uncle Gilles Dufour. The ceremony will take place in one of Paris's most important churches, nearly two weeks after the passing of the woman who held the position of Director of Public Relations for Christian Dior Couture and who, over the years, had become a key figure at the House of Dior.
Nicolas Altmayer: a private funeral
The family of Nicolas Altmayer, 61, has also set his funeral for Monday, August 31. Unlike Mathilde Favier's, however, his religious ceremony will be private. No location or time has been announced. His four children, Candice, Roxane, Félix, and Alice Altmayer, their mother Nadine Leignel-Altmayer, his son-in-law Louis Janssens van der Maelen, and other family members have announced the ceremony. Among them are Isabelle and Michel Barnier and their children, Emmanuel and Florence Altmayer, Ségolène Altmayer-Missoffe, Christian and Dorothée Altmayer, Éric and Brenda Altmayer, and Sébastien Mosneron Dupin. Nicolas Altmayer was a prominent figure in French film production. At the helm of Mandarin & Compagnie with his brother Éric, he notably produced OSS 117 , Brice de Nice , Frantz , Saint Laurent , Monsieur Aznavour , and Alpha . His passing prompted numerous tributes in French cinema, particularly from Jean Dujardin , who had worked with him for over twenty years, and Franck Gastambide , who considered him his producer, mentor, and close friend.
The two families are sharing their grief.
Both death notices share a particularly powerful common message. Mathilde Favier's family "joins in the grief of the loved ones of Nicolas Altmayer, who died alongside Mathilde ." Similarly, Nicolas Altmayer's family "joins in the grief of the loved ones of Mathilde Favier, who died alongside Nicolas ." Both families thus chose to explicitly refer to the other victim in each announcement, reminding everyone that Mathilde Favier and Nicolas Altmayer lost their lives together in the same accident.
A fatal accident occurred on August 17th in Deux-Sèvres.
Mathilde Favier and Nicolas Altmayer died on Monday, August 17, 2026, around 16 p.m., on the D938 near Airvault, in the Deux-Sèvres department. Their car collided with a truck traveling in the opposite direction. The circumstances of the tragedy subsequently took a significant turn. According to initial information released by the Niort prosecutor's office, the truck swerved toward their car before crossing the solid white line. The truck driver offers a different version of events, claiming that Mathilde Favier and Nicolas Altmayer's vehicle veered off course. A judicial inquiry for "involuntary manslaughter by a driver" has been opened to precisely determine responsibility. The tragedy has caused profound grief in two worlds to which the couple was closely connected: fashion and film. Mathilde Favier was one of Dior's behind-the-scenes faces, working closely with the house's international artists and personalities, while Nicolas Altmayer had supported and produced some of the biggest French film successes of recent decades. Monday, August 31st will now mark the time for farewells: at Saint-Sulpice for Mathilde Favier, and privately for Nicolas Altmayer.
