From a New York Times obit by Clay Risen headlined “Carl Croneberg, Explorer of Deaf Culture, Dies at 92”:

Carl Croneberg, a deaf Swedish immigrant who helped write the first comprehensive dictionary of American Sign Language and was the first to outline the idea of Deaf culture as a distinct part of society and one worth studying, died on Aug. 7.

His death was announced by Gallaudet University in Washington, D.C., the only university for the hearing-impaired in the United States, where he earned a degree and spent his entire career.
