Born in Berlin in 1946, Patrick Auffay is an actor who left a short but lasting mark on one of the most special periods of French cinema. The brightest moments of his career date back to his collaboration with François Truffaut, the pioneer of the French New Wave. Auffay entered the cinema at a young age and gained her real recognition in Truffaut's 1959 film The 400 Blows. He played Antoine Doinel's close friend René in this masterpiece that went down in world cinema history. This film, which is about a semi-autobiographical character, tells the story of young Antoine's struggle to grow up in the face of family conflicts and social pressures, while René represents the figure of a loyal friend who shelters him. The film won the Directing Award at the Cannes Film Festival and had a great impact in the international arena, and Auffay's name was a part of this success. Truffaut continued the character of Antoine Doinel in a series of films over the years, and Auffay also appeared in the second part of this series. Created in 1962, Antoine et Colette was part of the Vingt Ans d'Amour anthology, which consisted of short films by five different directors. While Truffaut once again focused on young Antoine on the verge of love in this episode, Auffay once again took on the role of René and gave continuity to the character. Although Auffay's acting career was not long-lasting, her performance in the most important moments of the French New Wave solidified her place in cinema history. The natural and sincere acting exhibited by Truffaut in these works reflected both the spirit and aesthetic understanding of that period. Patrick Auffay, who passed away in 2009, continues to live in a permanent memory with his contribution to cinema.
