The first modern linguistic analysis of a signed language was published in
1960 - William Clarence Stokoe's (1919-2000) Sign Language Structure. Altho
ugh the initial impact of Stokoe's monograph on linguistics and education w
as minimal, his work formed a solid base for what was to become a new field
of research: American Sign Language (ASL) Linguistics. Together with the w
ork of those that followed (in particular Ursula Bellugi and colleagues), S
tokoe's ground-breaking work on the structure of ASL has led to an acceptan
ce of signed languages as autonomous linguistic systems that exhibit the co
mplex structure characteristic of all human languages.
