Catholic Church and health care
The famous Mother Teresa of Calcutta established the Missionaries of Charity in the slums of Calcutta in 1948 to work among "the poorest of the poor". Initially founding a school, she then gathered other sisters who "rescued new-born babies abandoned on rubbish heaps; they sought out the sick; they took in lepers, the unemployed, and the mentally ill". Teresa achieved fame in the 1960s and began to establish convents around the world. By the time of her death in 1997, the religious institute she founded had more than 450 centres in over 100 countries.
Maria Pia Mastena
Blessed Maria Pia Mastena (7 December 1881 - 28 June 1951) - born Teresa Maria - was an Italian Roman Catholic professed religious and the founder of the Religious Sisters of the Holy Face. Mastena fostered a deep devotion to the Holy Face of Jesus and tried to promote that devotion to others in her religious career as a nun. Mastena first desired the contemplative life but was denied this after she entered the convent since it was not a cloister. Instead she dedicated herself to teaching in several Italian cities after having left another convent and another religious order when she deemed contemplative life was not the life she felt God wanted for her. Her labors were dedicated instead to consolidating her new religious order which began to grow after World War II until her sudden death in 1951.
