an American physician from Hounsfield, New York. He invented a form of percussion powder and also the punch lock for igniting it, which made the flintlock musket obsolete. He discovered chloroform independently in 1831, by distilling chloride of lime with alcohol in a copper barrel, using it as a mild anesthetic in amputation surgeries. The same chemical compound was discovered independently by a French scientist, Eugène Soubeiran, in October 1831, and by the German chemist Justus Liebig in November 1831, but Guthrie wrote of his findings in the summer of the same year, so he is generally acknowledged as the discoverer.
