TRANSCRIPT

Vulcanized Rubber Charles Goodyear 1844 Process of refining rubber and other polymers into a useable form Made it retain elasticity and withstand lower temperatures Bessemer Steel Making Process Henry Bessemer 1855(56) First inexpensive industrial process for refining and mass producing steel Pig iron must be refined before it is strong enough to be of use The Bessemer process removes impurities Dynamite Alfred Nobel 1867 Discovered a way to combine nitroglycerin with a stabilizing agent- made it into a paste- gave the previously volatile substance industrial applications Nobel left his vast fortune to sponsor awards for advances in the sciences Nobel peace prizes Induction Motor and Alternating Current Nikola Tesla 1888 Originally worked with Edison but broke off to follow his own lines of experimentation Induction motor enabled the mass production of machinery Steam Engine James Watt 1769 Did not create the steam engine- but saw the inefficiency Improved condensing chamber so as to lose less energy Steam Boat Robert Fulton 1807 Did not create the first steam boat, but perfected it for commercial uses The Clermont- 150 miles in 32 hours Bicycle Baron von Drais 1817 Invented to help him get around the royal German gardens faster Pushed with your feet Followed by the Velocipide had pedals Became a practical, inexpensive method of transportation Dirigible Henri Giffard 1852 French engineer Connected a small steam powered engine to a large propeller, topped at 5 mph Elevator Elisha Otis 1853 Did not invent the first elevator First freight elevator and braking system that eventually made skyscrapers possible Airplane Orville and Wilber Wright Dec. 17, 1903 in Kitty Hawk, North Carolina 12 second flight First powered, controlled flight Fords Model T Henry Ford 1909 Did not invent the automobile or the assembly line, but created cars affordable to the masses First gasoline engine 1885 Karl Benz Telegraph Samuel Morse 1837 Developed from crude, earlier models- submitting electrical current over wire Morse code in 1838 Photography Louis Daugerre 1839 Captured images by exposing plates to mercury and silver nitrate- decreased exposure time from previous attempts Typewriter Christopher Sholes 1868 Wisconsin newspaper man Improved after initial patent and manufactured starting in 1871 Easier for mass production of media- magazines, newspapers, etc. Phonograph Thomas Alva Edison 1878 Came from his work with the telegraph and telephone Recorded sound waves onto a metal cylinder Telephone Alexander Graham Bell 1876 Vast potential far exceeded that of the telegraph Wireless Telegraph Guglielmo Marconi 1897 Goal was to use radio waves to transmit Morse code signal as used for conventional wired telegraphs Received a Nobel prize in 1909 Canning Process Nicholas Appert 1810 Won the French prize for discovering a new method for preserving food Sewing Machine Elias Howe 1846 New apparatus made stitches uniform and increased output- industrialized textile industry Light Bulb/Electric Light Thomas Alva Edison 1879 Tested 3,000 different methods for developing an incandescent light bulb Kinetescope Thomas Alva Edison 1891 Ribbon of pictures run at speed through a camera opening One of many attempts at moving pictures of the day Discussion What do you think is meant by the phrase Necessity is the Mother of Invention? Why do you think these inventions came about at these specific times?
