The current interest in sign language bas roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D.C., the world's only liberal arts university for deaf peoplE.When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd among themselves, students signed differently from his classroom teacher.Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language(ASL) was thought to be no more than a form. of pidgin English(混杂英语). But Stokoe believed the 'band talk' his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on Earth? It was 1955, when even deaf people dismissed their signing as 'substandard'. Stokoe's idea was academic heresy(异端邪说).It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution.
