Improvement in Exploding Nitro-Glycerine | 1870s | A. Nobel

The creation of dynamite, which Alfred Nobel (of Nobel Prize fame) patented in 1867, was his second important achievement. By coincidence, nitroglycerin was completely absorbed by kieselguhr, a porous siliceous soil, and the resultant combination proved much safer to use and handle than nitroglycerin alone. Nobel's popularity spread over the globe, and dynamite was quickly employed effectively and efficiently to safely blast ditches, dig canals, and construct trains and roads.
