Théophile Malo de la Tour d'Auvergne-Corret, born on 23rd November 1743 in Carhaix and died on 27th June 1800 (at the age of 56) in Oberhausen, Bavaria, was a 'First Grenadier' in the French army.
La Tour d'Auvergne was also Celtic scholar ( we owe the words 'menhir' and 'dolmen' to him), a lover of Gallic antiquities and of Celtic languages (particularly Breton), together with the lawyer Le Brigant (a part time archeologist).
Death prevented La Tour d'Auvergne-Corret publishing a polyglot dictionary, where he compared 45 languages with Breton . He had tidied it up before his last departure with the army on the Rhine. In his book 'Origines Gauloises', published in 1792, he presents the Breton language as being the oldest in the world.
