Deaf culture
In 1972, Professor James Woodward, co-director of the Centre for Sign Linguistics and Deaf Studies at the Chinese University of Hong Kong since 2004, proposed a distinction between deafness and the Deaf culture. He suggested using "deaf" (written with a lower case "d") to refer to the audiological condition of deafness, and "Deaf" (written with an upper case "D") to refer to Deaf culture.
