Alfred Nobel, born October 21, 1833 in Sweden, was an inventor known for dynamite (1867), gelignite (1875), the detonator (1864), and ballistite (1887). His inventions facilitated large infrastructure projects and improved manufacturing, but they were also used in war and caused environmental damage due to mining and intensive construction. Nobel left a dual legacy: he revolutionized engineering and industry, but his products had negative effects. His Nobel Prize foundation promoted advances in science, literature and peace, underscoring its positive impact on humanity.​
