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.

Who Invented Phonograph


















Thomas Alva Edison Inventor of Phonograph

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.


The phonograph, record player, or gramophone is a device introduced in 1877 for the recording and reproduction of sound recordings. The recordings played on such a device generally consist of wavy lines that are either scratched, engraved, or grooved onto a rotating cylinder or disc. As the cylinder or disc rotates, a stylus or needle traces the wavy lines and vibrates to reproduce the recorded sound waves.

Who Invented Bubblegum


















Bubble gum inventor Walter E. Diemer (January 8, 1904—January 9, 1998)

Walter E. Diemer - Born and raised in Philadelphia, Pennsylvania, Diemer was working as an accountant at Fleer in 1926 when the company president sought to cut costs by making their own gum base. The company's founder, Frank Henry Fleer, had previously made a batch of bubble gum in 1906 which he called "Blibber Blubber", but it was too sticky and easily broke.

Bubblegum is a type of chewing gum, designed to be inflated out of the mouth as a bubble. As with chewing gum, the product is made from chicle and is available in various flavors.
