Rarely does ingenuity find just reward. The enterprising Nicolas Appert learned this unhappy fact when, in 1795, he hit upon the means by which to preserve meat, fish and vegetables in glass bottles. This découverte came only after a serious of professional failures. Appert began his career as a champagne salesman, and then tried his hand at confections before ending up in a grubby little atelier in the rue de la Folie-Méricourt, immersing in a piping hot bain-marie wide-mouthed glass bottles stuffed with everything from peas to pot roast. Finding that the bath rendered the jars airtight, Appert hit upon an idea that, for a few years at least, would bring him fame and welcome fortune.
