title: [The Father of sign language].
abstract: During the 19th century, doctors confronted with deafness (among whom Itard) played an essential part in the understanding of the diseases of the ears and the education of deaf mutes. Then in the 20th century the use of cochlear implants was a great leap forward, but a great problem too, deaf mutes not considering themselves as patients or disabled persons.
