Who was Mother Teresa?

Mother Teresa, the Roman Catholic nun who worked with the poor in the Indian city of Kolkata (Calcutta), is being declared a saint.

The order she founded, the Missionaries of Charity, has grown to include 4,500 nuns and 400 brothers in 87 countries, tending to the poor and dying in the slums of 160 cities.

She decided as early as 12 that she wanted to become a missionary in India.
