Owned by the confectionery giant Mondelez International, LU (Lefèvre-Utile) is an esteemed French biscuit brand founded in 1846 by Jean-Romain Lefèvre and Pauline-Isabelle Utile in Nantes. The brand became an icon of culinary heritage with the 1886 creation of the Petit-Beurre, a classic butter biscuit featuring a distinctive design of four “ears” and fifty-two “teeth” representing the seasons and weeks of the year. Throughout its history, LU has been a pioneer in both advertising—collaborating with artists like Alphonse Mucha—and product innovation, producing household favorites such as Prince, PIMS, and Mikado. Today, LU remains one of the world’s most successful biscuit manufacturers, blending its rich French artisanal roots with modern sustainability efforts like the Harmony Program, which promotes biodiversity and local wheat farming, ensuring the brand continues to symbolize high-quality, nostalgic snacking for generations of consumers across Europe and beyond.
