dec 27, 1881 - Sickness
When Helen Keller was only a year and a half year old, she got what is known as Meningitis. Over the course of a few months, she gradually lost her hearing and vision. By the age of two, she was completely blind and deaf.
Meningitis is a brain disease, that causes the brain to swell. This causes the parts of the brain that control sight and hearing to not work the way they are supposed to.
