Louis Laurent Marie Clerc was a French teacher called "The Apostle of the Deaf in America" and was regarded as the most renowned deaf person in American Deaf History. He was taught by Abbé Sicard and deaf educator Jean Massieu, at the Institution Nationale des Sourds-Muets in Paris. With Thomas Hopkins Gallaudet, he co-founded the first school for the deaf in North America, the Asylum for the Education and Instruction of the Deaf and Dumb, on April 15, 1817, in the old Bennet's City Hotel, Hartford, Connecticut. The school was subsequently renamed the American School for the Deaf and in 1821 moved to 139 Main Street, West Hartford. The school remains the oldest existing school for the deaf in North America.

Deaf culture is the set of social beliefs, behaviors, art, literary traditions, history, values, and shared institutions of communities that are influenced by deafness and which use sign languages as the main means of communication. When used as a cultural label, especially within the culture, the word deaf is often written with a capital D and referred to as "big D Deaf" in speech and sign. When used as a label for the audiological condition, it is written with a lower case d. Carl G. Croneberg coined the term "Deaf Culture" and he was the first to discuss analogies between Deaf and hearing cultures in his appendices C/D of the 1965 Dictionary of American Sign Language.
