Why do we celebrate #NationalASLDay on April 15th? On April 15, 1817, the first school for the Deaf opened in the United States. Together students used French Sign Language, Native American Signs, and Martha’s Vineyard signs. This process brought forth American Sign Language. . . . #aslday #americansignlanguage #asl #signlanguage #signing #deafcommunity #serveky #sharethelex #keeplouisvilleweird #sharelouisville #theville #bgky #soky #Kentucky #kyforky #kyproud #onthetablelex #nolicdc #nonprofits #interpreting #translating #interpreters #translators
