1867 CE
An explosion at the Nobel factory in 1864 kills five people, including Immanuel Nobel’s younger son, Emil.
Surviving son Alfred, searching for a safe way of handling nitroglycerine, discovers than an organic packing material can absorb the liquid in nitroglycerine, reducing its volatility.
Settling on the diatomaceous earth kieselguhr as an appropriate packing material for nitroglycerine, Nobel patents the mixture in 1867 under the name dynamite.
