Industrialist Alfred Nobel invented the detonator for dynamite and nitroglycerin

Swedish industrialist, engineer, and inventor, Alfred Nobel built bridges and buildings in Stockholm. His construction work inspired Nobel to research new methods of blasting rock.

The Nobel Patent Detonator - Blasting Cap

In 1863, Alfred Nobel invented the Nobel patent detonator or blasting cap for detonating nitroglycerin and dynamite. The Nobel patent detonator used a strong shock rather than heat combustion to ignite the explosives. In 1865, the Nobel Company built the first factory that made nitroglycerin and later dynamite.

Nitroglycerin and Dynamite

Nitroglycerin was first invented by Italian chemist Ascanio Sobrero in 1846. In its natural liquid state, nitroglycerin is very volatile. Albert Nobel understood this and in 1866 he discovered that mixing nitroglycerine with silica would turn the liquid into a malleable paste, called dynamite. One advantage of dynamite over nitroglycerin was that it could be cylinder-shaped for insertion into the drilling holes used for mining.

Albert Nobel Patents Dynamite

In 1867, Albert Nobel received U.S. patent number 78,317 for his dynamite. To be able to detonate the dynamite rods, Nobel also invented a detonator or blasting cap that was ignited by lighting a fuse.
