Why was the dynamite invented?

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. In 1860, the inventor first started experimenting with nitroglycerine. In 1863, Alfred Nobel invented the Nobel patent detonator or blasting cap for detonating nitroglycerin. The Nobel patent detonator used a strong shock rather than heat combustion to ignite the explosives. The Nobel Company built the first factory to manufacture nitroglycerin and dynamite.
