Who Invented Dynamite

Alfred Bernhard Nobel About this sound listen (21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, innovator, and armaments manufacturer. He was the inventor of dynamite. Nobel also owned Bofors, which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannon and other armaments. Nobel held 350 different patents, dynamite being the most famous. He used his fortune to posthumously institute the Nobel Prizes. The synthetic element nobelium was named after him. His name also survives in modern-day companies such as Dynamit Nobel and Akzo Nobel, which are descendants of the companies Nobel himself established.

Dynamite is an explosive material based on the nitroglycerin, initially using diatomaceous earth, or another absorbent substance such as powdered shells, clay, sawdust, or wood pulp. Dynamites using organic materials such as sawdust are less stable and such use has been generally discontinued.

Who Invented Revolver

Samuel Colt (July 19, 1814 – January 10, 1862) was an American inventor and industrialist from Hartford, Connecticut. He was the founder of Colt's Patent Fire-Arms Manufacturing Company (now known as Colt's Manufacturing Company), and made the mass-production of the revolver commercially viable for the first time.

Elisha Haydon Collier (1788–1856) of Boston invented a flintlock revolver around 1814. His weapon is one of the earliest true revolvers, in contrast to the earlier pepperboxes which were cumbersome and inaccurate multi-barreled guns prone to misfires, or even exploding. In addition to being single-action, Collier's revolver was self-priming: a compartment automatically released gunpowder into the pan when the hammer was cocked.

A revolver or six-shooter (as most revolvers have a maximum capacity of six rounds) is a repeating firearm that has a cylinder containing multiple chambers and at least one barrel for firing. The first true revolver—a flintlock—was made by Elisha Collier in 1814. The percussion cap revolver was invented by Samuel Colt in 1836. This weapon became known as the Colt Paterson. The first cartridge revolvers were produced around 1856 by Smith & Wesson. Though the original name was "revolving gun", the short-form "revolver" is universally used.
