The American School for the Deaf opened in Hartford, Conneticut. It was founded by Thomas Hopkins Gallaudet and Laurent Clerc, a Deaf educator from France. The school played a major role in the development of ASL. 

The U.S. government authorized the creation of what is now Gallaudet University in Washington, D.C. - the world's only university specifically desined for Deaf and hard of hearing students. It remains an international leader in Deaf education and research. 

Linguist William Stokoe published groundbreaking research showing that ASL has its own grammar and structure, proving it is a complete language rather than a system of gestures. His work changed how ASL was viewed around the world. 

Students at Gallaudet University organized the historic Deaf President Now (DPN) movement after a hearing president was selected over qualified Deaf candidates. The protest led to the appointment of Dr. I. King Jordan, Gallaudet's first Deaf president, and became a defining moment in the Deaf civil rights movement. 

The Americans with Disabilities Act (ADA) became law, expanding civil rights protections and improving accessibility for individuals with disabilities, including members of the Deaf community. The momentum created by the Deaf President Now movement helped bring national attention to disability rights.
