Hubert Cecil Booth (4 July 1871 – 14 January 1955) [1] was an English engineer, best known for having invented one of the first powered vacuum cleaners. [2] [3] [4] [5]He also designed Ferris wheels, [1] [6] suspension bridges and factories. [1]
Although vacuum cleaner and the short form vacuum are neutral names, in some countries (UK, Ireland) hoover is used instead as a genericized trademark, and as a verb.The name comes from the Hoover Company, [1] one of the first and most influential companies in the development of the device.
An early electric vacuum cleaner by the Electric Suction Sweeper Company, circa 1908, predecessor of the Hoover vacuum cleaner (1922).. This is a list of vacuum cleaners and robot vacuum cleaner manufacturers.
Evangelista Torricelli's mercury barometer of 1643 and Blaise Pascal's experiments both demonstrated a partial vacuum. In 1654, Otto von Guericke invented the first vacuum pump [19] and conducted his famous Magdeburg hemispheres experiment, showing that, owing to atmospheric pressure outside the hemispheres, teams of horses could not separate ...
Wellcome V0005861 Torricelli invented the mercury barometer, recorded in the books of Camille Flammarion (1923) Torricelli's experiment was invented in Pisa in 1643 by the Italian scientist Evangelista Torricelli (1608-1647). The purpose of his experiment is to prove that the source of vacuum comes from atmospheric pressure. [1]
1650: Vacuum pump: Invented by Otto von Guericke. [393] 1656: Pendulum clock: Invented by Christiaan Huygens. It was first conceptualized in 1637 by Galileo Galilei but he was unable to create a working model. [394] 1663: Friction machine: Invented by Otto von Guericke. 1668: First functional reflecting telescope constructed by Isaac Newton. [395]
He invented his first vacuum cleaner, called the Domestic Cyclone, in 1906, which was a hand-powered canister cleaner that used a water filtration system. His first portable vacuum cleaner for home use was manufactured and distributed by Franz Premier Electric, which was founded to produce Kirby's vacuum in 1914.
1650 – Otto von Guericke designed and built the world's first vacuum pump and created the world's first ever vacuum known as the Magdeburg hemispheres to disprove Aristotle's long-held supposition that 'Nature abhors a vacuum'. 1656 – Robert Boyle and Robert Hooke built an air pump on this design.
