Together, they established the first deaf school in the United States on April 15, 1817 in Hartford, Connecticut; it was named the Connecticut Asylum for the Education and Instruction of Deaf and Dumb Persons. The school taught in French Sign Language and a version of de l’Épée's methodical sign taught by Clerc and Thomas Hopkins Gallaudet.[4] The students attending the school had some knowledge of an indigenous sign language used in Martha's Vineyard, Massachusetts. Out of the blend of Martha's Vineyard Sign Language and French Sign Language, emerged American Sign Language.[2]
