Carl Gustav Arvid Olof Croneberg[1] (April 26, 1930 – August 7, 2022) was a Swedish-American Deaf linguist known for his work on American Sign Language (ASL).

He lost his hearing at the age of 10 and was subsequently sent to a Deaf institution where he was educated in Swedish Sign Language.

[2][3][4] In 1958, Croneberg was recruited by William C. Stokoe to work in a research laboratory for a linguistic analysis of the language of signs.

Alongside researchers William C. Stokoe and Dorothy S. Casterline, he noticed that ASL has a linguistic system (phonology, morphology, syntax).

[6] In the book, Croneberg gave an early ethnographic and sociological portrait on the Deaf community and its regional dialects.
