Born inCasoria, near Naples, ArcangeloPalmentieri was a cabinet-maker before entering the Friars Minor in 1832, taking the name Ludovico. After his ordination five years later, he taught chemistry, physics, and mathematics to younger members of his province for several years
In 1847, he had a mystical experience which he later described as a cleansing. After that, he dedicated his life to the poor and the infirm, establishing a dispensary for the poor, two schools for African children, an institute for the children of nobility, as well as an institution for orphans, the deaf, and the speechless, and other institutes for the blind, elderly, and for travelers. In addition to an infirmary for friars of his province, he began charitable institutes in Naples, Florence, and Assisi. He once said, “Christ’s love has wounded my heart.” This love prompted him to great acts of charity.
