american sign language was brought to america from which country
American Sign Language ASL is thought to have originated in the American School for the Deaf (ASD), founded in Hartford, Connecticut in 1817.[7]:4 Originally known as The American Asylum, At Hartford, For The Education And Instruction Of The Deaf And Dumb, the school was founded by the Yale graduate and divinity student Thomas Hopkins Gallaudet.[17][18] Gallaudet, inspired by his success in demonstrating the learning abilities of a young deaf girl Alice Cogswell, traveled to Europe in order to learn deaf pedagogy from European institutions.[17] Ultimately, Gallaudet chose to adopt the methods of the French Institut National de Jeunes Sourds de Paris, and convinced Laurent Clerc, an assistant to the school's founder Charles-Michel de l'Épée, to accompany him back to the United States.[17][nb 2] Upon his return, Gallaudet founded the ASD on April 15, 1817.[17]
Signing of the United States Constitution The Signing of the United States Constitution occurred on September 17, 1787, at Independence Hall in Philadelphia, Pennsylvania, when 39 delegates to the Constitutional Convention, representing 12 states (all but Rhode Island, which declined to send delegates), endorsed the Constitution created during the four-month-long convention. In addition to signatures, this endorsement, the Constitution's eschatocol, included a brief declaration that the delegatesâ€™ work has been successfully completed and that those whose signatures appear on it subscribe to the final document. Included are, a statement pronouncing the document's adoption by the states present, a formulaic dating of its adoption, along with the signatures of those endorsing it. Additionally, the convention's secretary, William Jackson, signed the document to authenticate the validity of the delegate signatures. He also made a few secretarial notes.
