In terms of civilian uses, the technique of gunpowder blasting for mining was first demonstrated by Caspar Weindel at Schemnitz, Lower Hungary in 1627.  A hole was drilled behind a rock and a fuze ignited the gunpowder, which broke up the rock. The technique spread acros s western Europe by the 1660s, greatly facilitating mining operations.  In mining gunpowder was replaced by dynamite, invented in the late 1860s by Swedish chemist [[Alfred Nobel], who endowed the Nobel prizes.
