Which organization was founded in 1890 to advocate for the Deaf community?

The National Association of the Deaf (NAD) was founded in 1880, not 1890, and is recognized as the earliest organization specifically devoted to advocating for the rights and welfare of deaf individuals in the United States. The NAD has played a critical role in promoting equal access to education, advocating for civil rights, and increasing awareness and understanding of Deaf culture and American Sign Language. Its formation was a response to the growing concern among the Deaf community regarding societal attitudes, education policies, and the need for cohesive representation.

This organization has been pivotal in many historical movements and legal advancements that benefit the Deaf community. Its emphasis on advocacy, support for deaf education, and the promotion of Deaf culture had significant implications for the community's visibility and representation in society.
