Peter Woulfe

Peter Woulfe (* 1727; ? † 1803) was an Irish chemist and mineralogist who first had the idea that wolframite might contain a hitherto unknown chemical element.

Woulfe reported of the formation of a yellow dye as indigo is treated with nitric acid. Later it was discovered that he had synthesized picric acid, which was eventually used as a dye, explosives and antiseptic for burns.

He is also the inventor of the Woulfe'schen apparatus ( Woulfesche bottle), a two-or three-necked bottle, which is mainly used as a condenser for vapors and gases, but also to treat liquids with gases or gases to wash.
