About National ASL Day
On April 15th 1817, the first lasting school for the deaf in the United States opened. Students gathered there over the years and at subsequent deaf schools across America.
The children intermingled Native American Signs, French Sign Language, and Martha’s Vineyard Sign Language. This process brought forth modern American Sign Language.
