Peter Woulfe

Encyclopedia : P : PE : PET : Peter Woulfe

Peter Woulfe (1727? – 1803) was an Irish chemist and mineralogist who first had the idea that wolframite might contain a previously undiscovered element.

Woulfe reported the formation of a yellow dye when indigo was treated with nitric acid. Later it was discovered by others that he had formed picric acid, which eventually was used as a dye, an explosive and an antiseptic treatment for burns.
