Education of Deaf-Mute and Development of the Sign Language in Bloomington, MN

For a long period of years, a child who was born deaf or blind has been called a defective. The belief that the deaf and blind could not be educated was so universal that within the last century they were actually referred to as children of "silence," "solitude" and "darkness," "sorrow-stricken children of silence", the pitiable object of dismal despair." How has it evolved?
This book deals with the history of the sign language and the evolution of the education of deaf-mute.
