The Gilded Gallows of Georg Honauer

[Paul Ferguson]

"Honauer was born in Olomouc, Moravia (now in the Czech Republic), in 1572. Passing himself off under his alias as a goldsmith and alchemist, in 1596 he entered the service of Friedrich I, Duke of Württemberg, in Stuttgart, claiming to be able to convert iron into precious metal using a process that combined alchemical transmutation with the bulk techniques of metal ore smelting."
