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.
