She's a virtual brand name when it comes to charity. Mother Teresa won the 1979 Nobel Peace Prize for her unending work with some of the world's most impoverished people.
In 1950, Mother Teresa launched a Catholic organization called the Missionaries of Charity, which began its work in India, helping to ease the suffering of poor, sick and orphaned people. In time, the charity grew to care for AIDS sufferers and people displaced by war, famine and other catastrophes, both natural and human-caused.
She remained committed to the charity for more than 40 years. She died in 1997, but many carry on her mission. Her organization is still active in more than 130 countries, with thousands of sisters tending to those in need. In doing so, they maintain a humanitarian presence in communities where no one else has the means or will to help.
