​SICARD, ROCH-AMBROISE CUCURRON (1742-1822), French abbe and instructor of deaf-mutes, was born at Le Fousseret, Haute-Garonne, on the 20th of September 1742. Educated as a priest, he was made principal of a school of deaf-mutes at Bordeaux in 1786, and in 1789, on the death of the Abb6 de l'Epee (see £pee), succeeded him at Paris. His chief work was his Cows d 'instruction d'un sourd-muet de naissance (1800). See Deaf and Dumb. The Abb6 Sicard managed to escape any serious harm in the political troubles of 1792, and became a member of the Institute in 179S, but the value of his educational work was hardly recognized till shortly before his death at Paris on the ioth of May 1822.
