Juan Nepomuceno Zegrí y Moreno was a 19th-century Spanish priest who established the Mercedarian Sisters of Charity in 1878. Born in Granada, he served as a parish priest and a canon of the Málaga Cathedral, while also acting as a chaplain to Queen Isabel II. Despite facing serious allegations of misconduct in 1888, he was eventually cleared of all charges by the Holy See in 1894. He is recognized as a saint and the founder of his religious congregation.
