Nobel Nobel, Alfred (1833 – 1896)

Nobel discusses patent applications for his explosives

An extremely rare one-page autograph letter signed by Alfred Nobel, 31st March 1882.

Nobel writes in German to Messrs. Mahler and Eschenbacher in Vienna. In full, “In the English patent I applied for already in December 1875, ammoniac gelatine is also one of the mixtures involved. In Sweden a special patent was applied for on the wish of the Nfl Corporation. Should further information be desirable, I ask you to have the kindness to let me know.” In very fine condition.

The patent that Nobel discusses here certainly concerns one of his inventions involving explosives. Guhr dynamite was invented in 1867 but had certain technical weaknesses. Continuing his research, Nobel created blasting gelatin in 1875, a colloidal solution of nitrocellulose in nitroglycerin which in many respects proved to be an ideal explosive.
