What it is

A tactile alphabet of raised six-dot cells, readable with the fingertip and writable with a stylus, created by Braille at the age of 15 from Charles Barbier's military 'night writing'. It gave blind people independent reading and writing.

Published in 1829 and refined in 1837; it was not officially adopted by the Institution until 1854, two years after Braille's death.
