Inventions (science & technology history): Identify the inventor of dynamite. Full question: Who invented dynamite, the safer explosive based on stabilized nitroglycerin introduced in the 19th century? Choose the correct option.

Given data

• Target: Name the inventor of dynamite.
• Context: Safer, packaged form of nitroglycerin for blasting and mining.

Concept / Approach
Dynamite is nitroglycerin absorbed in an inert, porous material (e.g., diatomaceous earth), creating a more stable explosive stick. It was introduced and patented by Alfred Nobel in the 1860s.

Option analysis
Alfred Nobel — Correct: patented dynamite in 1867. Ascanio Sobrero — Discovered nitroglycerin (1847) but did not invent dynamite. Lavoisier — Pioneered chemistry; not linked to dynamite. Mendeleev — Periodic table; not explosives.

Final Answer
Alfred Nobel.
