[originaltext] In a busy classroom filled with nearly 20 children, Sabriye Ten

In a busy classroom filled with nearly 20 children, Sabriye Tenberken lectures her pupils to always help others who need it. The children nod, leave their chairs and rush into the kitchen, ready for supper.
  The school, founded by Ms. Tenberken and her Dutch partner, Paul Kronenborg, is tucked away in a small alley, not far from a busy street in Lhasa. They founded Braille Without Borders, hoping that one day their work would not only help Tibetans, but also visually impaired people from other developing countries.
  Ms. Tenberken, a 34-year-old German woman who has been blind since the age of 12, pursued a master’s degree in Tibetan studies in her hometown, Bonn.
  When she realized that the Braille writing system for the blind did not exist in Tibetan, she developed one—in just two weeks. Braille uses raised dots on a page to create words—users feel the dots to read the page.
