This week is marked annually in honor of leading humanitarian Helen Keller’s birthday on June 27. Being deaf and blind herself, Keller’s work made a large difference in the lives of DeafBlind people. It is much more common than many people realize. Over 15 million people worldwide are estimated to be living with severe DeafBlindness. This week is a chance for us to raise awareness of deafblindness and make Pennsylvania a more DeafBlind-friendly place.
