"The romantic tales told of C.H. Sanson have their origin in the apocryphal Mémoires pour servir à l'histoire de la révolution française, par Sanson (2 vols., 1829; another ed. 1831), of which a few pages of introduction emanate from Balzac, and some other matter from Lhéritier de l'Ain. Other Mémoires of Sanson, ed. by A. Grégoire, (pseud. for V. Lombard) in 1830, and by M. d'Olbreuze (6 vols., 1862-1863) are equally fictitious."--Ency. Brit., 11th ed., v. 24, p. 183.
