Caterina Cittadini was a 19th-century Italian nun from Bergamo who founded the Ursuline Sisters of Saint Jerome Emiliani. After being orphaned as a child, she developed a profound faith while living in an orphanage. She dedicated her life to the education of young girls, establishing schools in Somasca that combined religious and civic instruction. Her commitment to teaching and her spiritual devotion led to the formal establishment of her religious congregation, which has since expanded beyond Italy to various parts of Europe and Asia.
