This is a short, 47 minute, Australian-Canadian documentary about the late Charles Bliss. Trained as a chemical engineer, Bliss survived Buchenwald and lived in China for six years before emigrating to Australia, where he developed a universal symbolic language, Blissymbolics. Bliss recounts his life and explains some of his work, and this documentary tells the story of how Canadian health workers in the early 1970s taught his symbols to children with cerebral palsy, enabling them to communicate their thoughts and feelings.
