Mother Teresa (1910-1997) founded the Order of the Missionaries of Charity, a Roman Catholic congregation of women dedicated to helping the poor. Though small in stature, she is considered one of the great humanitarians of the 20th century for her work among the poor and dying in India. She was canonized Saint Teresa of Calcutta in 2016 by Pope Francis. In her words, "Not all of us can do great things. But we can do small things with great love."
