Émile Littré (1 February 1801-2 June 1881) was a French lexicographer and philosopher, born in Paris and best known for his Dictionnaire de la Langue Française, commonly known as 'The Littré'. Littré started work on his great Dictionnaire de la langue Française in 1844, but it took him 30 years to finish it. In between, he participated in the July 1848 revolution, and in the repression of the extreme Republican Party in June 1849.
Littré published Comment j'ai fait mon dictionnaire in 1880, just a year before his death.
