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. In 1779, Woulfe reported the formation of a yellow dye when indigo was treated with nitric acid.

He is also credited with inventing the Woulfe Bottle, … Wikipedia
