Simply so, when was ASL first recognized as a language?

Oh sure, ASL has been used in America since theearly 1800's (and earlier if you include the signing that was beingdone in America prior to Thomas Gallaudet bringing Laurent Clercfrom France), but it wasn't until 1960 that "experts" startedrecognizing it as a full-blown autonomouslanguage.

Additionally, when was deafness first discovered? Starting to Educate the Deaf. Geronimo Cardano,an Italian mathematician and physician, was probably thefirst scholar to identify that learning does not requirehearing. He discovered, in the 1500s, that the deafwere able to be educated by using written words.

Similarly, it is asked, what language is sign language based on?

Because sign languages develop within deafcommunities, they can be independent of the surrounding spokenlanguage. American Sign Language (ASL) is quitedifferent from British Sign Language (BSL), despite the factthat English is the spoken language of bothcountries.

Who invented British Sign Language?

British Sign Language has evolved, as alllanguages do, from these origins by modification, inventionand importation. Thomas Braidwood, an Edinburgh teacher, founded'Braidwood's Academy for the Deaf and Dumb' in 1760 which isrecognised as the first school for the deaf inBritain.
