ACHARD, Franz Karl, äʜ′art, fränts karl, German chemist and physicist: b. Berlin, 28 April 1753; d. 1821. He published in 1780 the results of many and careful experiments on the adhesion of bodies. But later he devoted himself to the development of the beet-sugar manufacture, and after six years of laborious endeacor discovered the true method of separating the sugar from the plant. His process was of enormous service to the countries whom the Napoleonic blockade shut off from the West India sugars. He was afterward director of the class of physics in the Academy of Science in Berlin.
