September 2, 2016 5:24 PM EDT Mother Teresa will officially become a saint on Sunday, on the eve of the 19th anniversary of her death. The Roman Catholic nun, widely known for her dedication to humanitarian causes with the Missionaries of Charity, spent her life caring for poor and sick people. Photos of Mother Teresa throughout the years show her clad in a blue-trimmed white sari, assisting the sick, orphans, the homeless and others. In 1955, when her charity took in large numbers of abandoned children, Mother Teresa opened the Children’s Home of the Immaculate Heart to safely house them. Her work garnered several awards and recognition, including the 1979 Nobel Peace Prize.
Here, see Mother Teresa at work throughout her life—and the work that has continued, thanks to her legacy, in the years since her death.
