ASL emerged as a language in the American School for the Deaf (ASD), founded in 1817. This school brought together Old French Sign Language, various village sign languages, and home sign systems; ASL was created in this situation of language contact. ASL was influenced by its forerunners but distinct from all of them.
ASL was then invented using signs from French Sign Language, as well as signs from the community in Martha's Vineyard, and may have been influenced by the signing system of the Great Plains Native Americans.merican Sign Language. American Sign Language, or ASL became prominent in the 1800's thanks to Thomas Hopkins Gallaudet. He wanted to help Alice Cogswell who was his neighbor's deaf daughter, so he travelled to Europe to study how to communicate with deaf people.
