The modern recorded history of sign language began in the 17th century in Spain, in part with Bonet. In 1620, Juan Pablo Bonet published ReducciÃ³n de las letras y arte para enseÃ±ar a hablar a los mudos (Summary of the letters and the art of teaching speech to the mute) in Madrid. Considered the first modern treatise of the phonetics of sign language and the use of sign language to teach speech to the deaf, this book depicted Bonet's form of a manual alphabet. His intent was to further the oral and manual education of deaf people in Spain.
Forty years later, in 1857, Thomas Hopkins Gallaudet's youngest child, Edward Miner Gallaudet, came to Washington, D.C., where he established a school for deaf children. The school flourished and in 1864, a collegiate division was addedâand so began the world's only university for deaf and hard of hearing students.he History Behind DPN: What Happened...
