He made a lot of money from his gelignite invention

Later, Nobel blended nitroglycerin with additional substances. Additionally, he kept experimenting in quest of better ones, and in 1875 he created blasting gelatin, a more potent type of dynamite. He patented it the following year. Once more by accident, he had discovered that nitrocellulose, a fluffy substance, and nitroglycerin solution, when combined, produce a strong, plastic material with higher water resistance and greater blasting power than standard dynamite.

One of the first nitroglycerin smokeless powders and a forerunner to cordite, ballistite was originally made available by Nobel in 1887. Alfred amassed a sizable fortune thanks to his global investments in explosives and his stakes in his brothers' Russian business ventures. Gelignite, which was patented in 1876 and became the industry standard for mining during the Age of Engineering, brought Nobel enormous financial success. This is one of the most interesting facts about Alfred Nobel. Nobel owned the patents for dynamite and his other explosives, but he was frequently at odds with rivals who appropriated his ideas. As a result, he was frequently dragged into drawn-out patent disputes.
