On a day like today (November 25), 1867, Alfred Nobel patents an explosive he calls dynamite.
Alfred Nobel was a chemist, engineer, writer and inventor who during his lifetime obtained 355 different patents among which his most famous invention was dynamite. When he died he had 90 weapons factories throughout Europe.
As a young man he went to study chemistry in Russia and then in France. In Paris he coincided with Ascanio Sobrero who had just invented nitroglycerin, a powerful but very unstable explosive. Sobero was against using nitroglycerin as an explosive of any kind.
Soon, in a Nobel family factory, a brother of Alfred Nobel was killed by a random explosion of nitroglycerin. That prompted Alfred Nobel's efforts to find a more stable explosive material. Those investigations led to the development of dynamite.
Dynamite is a very powerful explosive composed of nitroglycerin, a highly unstable liquid explosive substance at room temperature that, when absorbed in a solid medium (initially a rock called diatomite), turns into a more stable explosive. Due to its high stability and safer storage, dynamite will quickly replace nitroglycerin in industries such as mining or demolition. It will also be used as an explosive filler in artillery shells and military demolition charges. Alfred Nobel will build numerous factories in Europe to meet the high demand for the product.
In 1888, the death of a brother, Ludwig, caused some newspapers to publish Alfred Nobel's obituary by mistake. In a French newspaper he headlined Alfred's obituary as "The Merchant of Death is Dead". This affected Alfred Nobel, who had no offspring, to think about what legacy he would leave for posterity and how he would be remembered. That ended up leading him to create a fund with a large part of his wealth for the creation and maintenance of a prize that would reward each year the greatest exponents of in Literature, Physiology o Medicine, Physics, Chemistry and Peace.
As a curiosity to mention that in 1991 the Ig Nobel Prizes were created, they are an American parody of the Nobel Prize. It is given out each year in early October to recognize the achievements of ten groups of scientists who "first make people laugh, then make them think" and is organized by the science humor magazine Annals of Improbable Research (AIR). Its goal is "The Awards are intended to celebrate the unusual, honor the imaginative, and stimulate everyone's interest in science, medicine, and technology."
