Sicard's chief works were his Eléments de grammaire générale (1799), Cours d'instruction d'un sourd-muet de naissance (1800) and Traité des signes pour l'instruction des sourds-muets (1808). The Abbé Sicard managed to escape any serious harm in the political troubles of 1792, and became a member of the Institute in 1795, but the value of his educational work was hardly recognized till shortly before his death at Paris.[3]

^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French. Conversely, ASL and BSL both originated in English-speaking countries but are not related to each other; ASL however is related to French Sign Language.
