French statesman (1787-1874) who served as the 22nd Prime Minister of France under King Louis Philippe I, forced to resign during the Revolution of 1848. He is remembered as the originator of the often-reworked quote, ‘Not to be a republican at 20 is proof of want of heart; to be one at 30 is proof of want of head.’ Partly-printed DS, in French, signed “Guizot,” one page, 10 x 15.25, July 19, 1841. Untranslated official appointment also signed by the Chief of the Chancellery. In very good condition, with a few separations along the intersecting folds of the lightweight paper, some tears to the edges, scattered creasing, and a light pencil notation away from the signature.
