Women in the Catholic Church
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.
Teresa Hsu
Teresa Hsu Chih (7 July 1898 – 7 December 2011) (), was a Chinese-born Singaporean social worker, known affectionately as "Singapore's Mother Teresa", in recognition for her active lifelong devotion in helping the aged sick and destitutes locally. The retired nurse was the founder of the non-profit charities—Heart to Heart Service and the Home for the Aged Sick, one of the first homes for the aged sick in Singapore. She had been a social worker in China and Paraguay and a nurse in England, before coming to Singapore to start similar non-profit charities since 1961. Despite being a supercentenarian, Hsu was still involved in charity work and was one of very few supercentenarians who were recognised for reasons other than their longevity. She had spent almost all her savings on feeding and housing the poor and the elderly, all of whom are younger than she was, but she herself led a simple and humble lifestyle. In 2005, she received the Special Recognition Award from the Singapore government in recognition of her contribution to the country.
