She was a healthy child who was born with her senses of sight and hearing, like all other children. At the tender age of 6 months, she had started to speak. When she was 18 months old, however, Helen Keller contracted an illness that produced a high body temperature. What it is exactly is not known, but many believe it could have been scarlet fever or meningitis. Some days after the fever broke, her mother noticed that she was not responding normally to sounds and light.
When she had recovered her health, she could no longer see or hear. The early loss of her sense of sight and sound caused Helen to have only a limited method of communication with her family. It also caused her to become very wild and unruly as she grew from infancy to childhood, possibly due to her inability to express her emotions appropriately through language and proper communication. Due to the loss of her special condition, she was very hard to teach or discipline.
Her mother searched arduously for suitable teacher, and later decided on Anne Sullivan, a recent graduate of Perkins Institute for the Blind. Their close relationship was known as a great contributor to Hellene success, but without the loss of her senses, none of it would have been possible. The illness she contracted at 1 8 months of age was the one event that led to many other events, like the meeting of Anne Sullivan, etc. If not for her disability, she might not have been where she was, in the end - a successful and inspirational woman to remember.
