World Braille Day, observed on 4 January, marks the birth anniversary of whom?

  1. A.Louis Braille
  2. B.Helen Keller
  3. C.Alexander Graham Bell
  4. D.Thomas Edison

Correct answer

A. Louis Braille

Explanation

The correct answer is A, Louis Braille, who was born in France on 4 January 1809. Blinded in an accident as a child, he devised the system of raised dots that allows blind and partially sighted people to read and write by touch, and the system carries his name.

Option B, Helen Keller, was a deaf and blind American writer and campaigner whose life is closely associated with the education of people with these disabilities, which makes her a convincing distractor here. Option C, Alexander Graham Bell, worked with the deaf and invented the telephone, so he belongs to a different field of communication. Option D, Thomas Edison, is remembered for the electric lamp and the phonograph. The United Nations recognised 4 January as World Braille Day to draw attention to braille as a means of full participation in society.
