HISTORY
1714 -Martha’s Vineyard had a very high population of Deaf individuals (as high as 1 in 4 in some areas), so residents created and learned Martha’s Vineyard Sign Language. Because of this, there was no communication barrier between deaf and hearing residents.
1760- French Sign Language was founded.
1816- Laurent Clerc, a Deaf man from France, was brought to the US by Thomas Gallaudet to help set up an educational institute for the deaf in America.

1864- President Lincoln signed off on an act that allowed for the establishment of a school of the Deaf, which remains the world’s only liberal arts university for deaf and hard of hearing students.
1872- Alexander Graham Bell founds oralist school. During his lifetime, Alexander Graham Bell widely promoted both eugenics and oralism, the belief that Deaf individuals should be taught speech and lip-reading over sign language. While his mother was Deaf, his father, Melville Bell, created ‘Visible Speech,’ a system of symbols meant to assist people in speaking languages they could not hear. Bell’s name became synonymous with oralism in the Deaf community.
