During her stay in Netherlands while hiding from the German forces, Anne Frank, a young jewish girl, was gifted a diary by her father when she was 13. However, her diary was published after her death in Bergen-Belsen concentration camp at the age of 15. The diary served as a unique eye-witness account of life during Holocaust (mass murder of approximately six million Jews during World War II) and it became one of the world's most read books.
Mother Teresa, the Nobel Peace Prize winner (1979), aimed at looking after those who had nobody to look after them through her own order "The Missionaries of Charity". She worked tirelessly towards her goal until her ill-health - that included two heart attacks, pneumonia and malaria - forced her to step down in March 1997, following which she took her last breath in September 1997.
