Alfred Nobel Obtains a Patent for Dynamite in England
Dynamite is an explosive material based on the explosive potential of nitroglycerin, initially using diatomaceous earth (kieselgur: United States spelling; kieselguhr: UK spelling) or another absorbent substance such as sawdust as an absorbent.
It was invented by Swedish chemist and engineer Alfred Nobel in Krümmel (Geesthacht, Schleswig-Holstein, Germany), and patented in 1867. Military dynamite achieves greater stability by avoiding nitroglycerin.
It is usually sold in the form of a stick 20 centimetres (roughly 8 inches) long and 2.5 centimetres (1 inch) in diameter, but other sizes also exist. Dynamite is considered a high explosive, which means it detonates rather than deflagrates. While TNT is used as the standard for gauging explosive power, dynamite actually has more than 60% greater energy density than TNT.
Dynamite was invented by Alfred Nobel and was the first safely manageable explosive stronger than black powder. Nobel obtained patents for his invention: in England on 7 May 1867 and in Sweden on 19 October 1867. He originally sold dynamite as "Nobel's Blasting Powder". After its introduction, dynamite rapidly gained popularity as a safe alternative to gunpowder and nitroglycerin. Nobel tightly controlled the patent, and unlicensed duplicators were quickly shut down. However, a few American businessmen got around the patent by using a slightly different formula.
