Leopold Bernard (1832-1867) was a gun, cannon, and barrel maker in Paris, and his company continued after his death until 1890. 'Bernard' was also a generic description of a damascus production technique and pattern. Many of the barrel makers in the 'Syndicat des Fabricants de canons de fusils de la Vesdre', Nessonvaux, made patterns they called Bernard; in I, II, and several grades.
