Saint Leonardo Murialdo (†1900) was an Italian Roman Catholic priest and the co-founder of the Congregation of Saint Joseph - also known as the Murialdines (which he founded alongside Eugenio Reffo). Murialdo's call to the priesthood did not manifest until late in his education in Savona; he pursued his ecclesial studies and was ordained as such in 1851 before dedicating himself to social work alongside the poor and with adolescent men. This put him into contact with other priests of the era such as Giovanni Bosco and Giuseppe Cafasso who held Murialdo in great esteem. His zeal for social concern saw his frequent calls for an end to worker exploitation and the granting of further rights to workers in factories. Murialdo died in the odor of holiness in 1900 and had a reputation for deep personal holiness. The cause for his canonization opened under Pope Benedict XV in 1921 with Pope John XXIII later confirming his heroic virtue and naming Murialdo as Venerable in 1961. Pope Paul VI beatified Murialdo in late 1963 and later canonized him just under a decade later in 1970. His feast day is celebrated on 30 March.
