Alfred Nobel invented dynamite. A Swedish chemist and engineer, he patented this safer explosive in 1867 by stabilizing nitroglycerin with kieselguhr. This breakthrough transformed mining, construction, and demolition while reducing accidental explosions.

Invention Backstory

Nitroglycerin, discovered earlier by Italian chemist Ascanio Sobrero in 1847, was notoriously unstable—often detonating unpredictably during transport or handling. Alfred's family had experience with explosives; his father, Immanuel Nobel, explored rock-blasting alternatives to black powder. Tragedy struck in 1864 when an explosion at the Nobel factory killed five, including Alfred's younger brother Emil, spurring Alfred to create a shock-resistant version.

Key Milestones

  • 1866 : Nobel develops dynamite by mixing nitroglycerin with diatomaceous earth (kieselguhr), forming a moldable paste.
  • 1867 : Patents filed in Sweden, UK, and US; named "dynamite" from Greek "dynamis" (power), rejecting "Nobel's Safety Powder".
  • Later innovations : Blasting gelatin (1875) enhanced power with nitrocellulose.

Impact and Legacy

Dynamite revolutionized industries, enabling massive projects like railroads, tunnels (e.g., Gotthard Tunnel), and the Panama Canal. Its military use earned Nobel the "merchant of death" moniker after a mistaken obituary about his brother. Shaken, he willed his fortune to fund the Nobel Prizes, starting 1901, promoting peace and science.

Common Misconceptions

Dynamite differs from TNT (trinitrotoluene), invented later by Germans in 1902—cartoons often confuse them. No recent discoveries; Nobel's credit remains undisputed as of January 2026.

TL;DR: Alfred Nobel discovered dynamite in 1867 to safely harness nitroglycerin's power.
