The Franck family have been innovators in perfume atomizers for over 140 years. In 1882, Leopold Franck picked up on the growing popularity of perfume and various different instruments used to spray fragrances. inspired, he started an industrial production of perfume atomizers which were quickly snapped up by department stores and perfumeries in France.
 
His son joined the business, and upon Leopold's death in 1907, Marcel took over, gaining contracts with major crystal companies like Baccarat and Saint Louis and employing the best glass artists including Lalique, Galle and Argy-Rousseau. The company turned atomisers into works of art, and the brand gained international recognition worldwide.
 
Shortly before his death, the company was sold and finally disappeared in the late 1990s. A very active collectors' market kept the brand alive. In 2013, Bernard Dennery, grand-son of Marcel Franck, revived the brand. His company follows the family tradition of high quality and innovation creating new patented spray systems today.
