Nobel's first patent

In 1863, Alfred Nobel was granted his first patent, a Swedish patent for the preparation of nitroglycerin. The end of the Crimean War (1856) brought bankruptcy for his father, Immanuel Nobel, whose factory manufactured war materiel. Studying chemistry, Alfred learned of the powerful new explosive, nitroclycerine. Around 1860, Alfred conducted repeated experiments involving great risks. He succeeded in manufacturing sufficient quantities of nitroglycerine without any mishaps. His father had been making similar experiments, but with less success. When his father realized his son's greater discoveries, he assisted Alfred patent the explosive that he aptly called "blasting oil." Later, in 1868, Nobel patented dynamite as a form for safer handling.
