Alfred Nobel

In 1863, Swedish industrialist Alfred Nobel invented the Nobel patent detonator (later used with dynamite) which detonated nitro-glycerin using a strong shock rather than heat combustion. In 1865, the Nobel Company built the first factory for producing nitro-glycerin and later dynamite. Nitro-glycerin in its natural liquid state is very volatile. Alfred Nobel recognized this, and in 1866, he discovered that mixing nitro-glycerin with silica would turn the liquid into a malleable paste (dynamite), which could be cylinder shaped for insertion into the drilling holes used for mining. In 1867, Alfred Nobel patented this material under the name of dynamite — U.S. Patent No. 78317. To be able to detonate the dynamite rods, he also invented a detonator or blasting cap that was ignited by lighting a fuse.
