CHAPTER 4:

 Wasnt French Sign Language invented by the Abbe' del' Epee?

No. French sign language was invented by deaf people, along with many other dialects of sign language. Although Epee was a "neiborhood priest" whose involvement with deaf people began in the mid- 1700s and who is now known as the first known educator, who bothered to learn from deaf people themselves.
Epee wanted to save deaf peoples souls from damnation, he researched information on deaf education and soon adapted the spanish fingerspelling. He was the first hearing person to go to the deaf community to learn its language.
Epee approached deaf people with an open mind, unlike previous educators who didnt take into account the fact that deaf people alread had a highly developed "visual" means  of communication.

Although Abbe' del' Eppe is an inspirational figure to many deaf people, he did not have anything to do with the invention of sign language, rather he recognized the importance of sign language as the best way to communicate with and educate deaf people.
