Mother Teresa of Calcutta
Mother Teresa (1910–1997), was an Albanian-Indian Roman Catholic nun and missionary. In 1950 she founded the Missionaries of Charity, a Roman Catholic religious congregation which was active in 133 countries as of 2012. The congregation manages homes for people dying of HIV/AIDS, leprosy and tuberculosis; soup kitchens; dispensaries and mobile clinics; children's- and family-counselling programs; orphanages, and schools. Members, who take vows of chastity, poverty, and obedience, also profess a fourth vow, to give 'wholehearted free service to the poorest of the poor.' Wikipedia article.
