Ascanio Sobrero (12 October 1812 – 26 May 1888) was an Italian chemist, born in Casale Monferrato. He was studying under Théophile-Jules Pelouze at the University of Turin, who had worked with the explosive material guncotton.

He studied medicine in Turin and Paris and then chemistry at the University of Gießen with Justus Liebig, and earned his doctorate in 1832. In 1845 he became professor at the University of Turin

During his research he discovered, in 1847, nitroglycerine.[1][2] He initially called it "pyroglycerine", and warned vigorously against its use in his private letters and in a journal article, stating that it was extremely dangerous and impossible to handle. In fact, he was so frightened by what he created that he kept it a secret for over a year.

Another of Pelouze's students was the young Alfred Nobel, who returned to the Nobel family's defunct armaments factory and began experimenting with the material around 1860; it did, indeed prove to be very difficult to discover how to handle it safely. In the 1860s Nobel received several patents around the world for mixtures, devices and manufacturing methods based on the explosive power of nitroglycerine, eventually leading to the invention of dynamite, ballistite and gelignite from which he made a fortune.

Although Nobel always acknowledged and honored Sobrero as the man who had discovered nitroglycerine, Sobrero was not only dismayed by the uses to which the explosive had been put, but also on occasion claimed that he was not given sufficient recognition.[3]

On p. 197, Sobrero names nitroglycerine "pyroglycerine": "Quelle gocciole costituiscono il corpo nuovo di cui descriverò ora le proprietà, e che chiamerò Piroglicerina." (Those drops constitute the new substance whose properties I will now describe, and which I will call "pyroglycerine".)
