Louis Casserole (born 1585 in Paris (France), died 1684 ib.), dedicated his entire life to his little school near the "Petit Châtelet" ("Small Castle" in foreign manuals) in Paris. This humble but erudite man has had amongst his pupils some of the greatest minds of XVIIth Century France. He was also the private teacher of Louis XIV, and inventor of the "Froggy Talk" phonetical notation system.
