AN 18TH-CENTURY GRAPHOMETER BY PIERRE GOURDIN
of typical form, signed by the arc Gourdin au Quart de Cercle à Paris, 1778, with ball and joint limb, contained within original fitted box -- 11in. (28cm.) diameter
Working between 1775 and 1800, Gourdin was twice rejected as an "Ingénieur du Roi", possibly because of professional protectionism from Charles-Joseph Meurand who made very similar instruments. His luck partially changed in 1794 when he was chosen to value mathematical instruments seized during the Revolution.
