(shärl mshl´ äb´ d lp´) (KEY) , 171289, French pioneer teacher of deaf-mutes. A Jansenist priest, he developed a manual system of communication for deaf-mutes and founded a school for their instruction in 1755. In 1776 he published a treatise on his educational method, which he later (1784) expanded as La Véritable Manière dinstruire les sourds et muets [the right way to teach deaf-mutes]. His dictionary of manual signs was completed after his death by Abbé Sicard, and in 1791 his school was taken over by the Institution nationale des Sourds-Muets à Paris.
