Lucien was a serious and diligent child who planned to attend the Ecole Centrale des Arts et Manufactures before his father, Alexis, announced he was to become a future partner in his relatively young firm, Falize.

His studies continued quickly, as Lucien found his passion, and in 1869 at the exhibition held by the Union Centrale des Beaux Arts appliqués à l’Industrie, he was awarded a First class medal as a coopérateur.

Although there is little evidence of tenderness and passion between Lucien and Clémentine – it is thought his parents instigated the match – he was a devoted father, designing and making individual silver watches for each of his children's first communion.

Lucien also visited the Campana collection at the Louvre, where he viewed a number of items, being influenced by the treasure trove of medieval, Renaissance, Assyrian, Egyptian, and Byzantine objects.

He firmly believed in the importance of providing proper training to future designers, and he submitted plans for technical exhibitions and donated working prototypes of chatelaines and electrotypes of bracelets.
