inventions during presidential terms

Inventions During Presidential TermsI have put in bold the inventions that I think are the most important. Things highlighted yellow (if you are familiar with last year’s invention list, you may not want to read this explanation) are those inventions which, since I do not know the month that they were invented, could conceivably be in the president previous, because presidents went into office in March back then. However, the chance is very slim, so if you want, you can ignore the yellow.George Washington #1: 1791: Artificial teeth: Nicholas Dubois De Chemant 1793: Cotton gin: Eli Whitney John Adams #2: 1798: Vaccination: Edward Jenner 1798: Lithography: Alois Senefelder Thomas Jefferson #3: 1801: Jacquard loom: Joseph Marie Jacquard 1802: Screw propeller steamboat Phoenix: John Stevens 1802: Gas stove: Zachäus Andreas Winzler 1804: Locomotive: Richard Trevithick 1805: Submarine Nautilus: Robert Fulton 1807: Steamboat Clermont: Robert Fulton 1808: Band saw: William Newberry James Madison #4: 1809: Arc lamp: Humphry Davy 1814: Steam Locomotive (Blücher): George Stephenson 1816: Miner's safety lamp: Humphry Davy 1816: Stirling engine: Robert Stirling 1816: Stethoscope: Rene Theophile Hyacinthe Laennec 1816: The Bicycle James Monroe #5: 1817: Draisine or velocipede (two-wheeled): Karl Drais 1817: Kaleidoscope: David Brewster 1821: Electric motor: Michael Faraday 1823: Electromagnet: William Sturgeon 1824: Portland cement: William Aspdin John Quincy Adams #6: 1826: Photography: Joseph Nicéphore Niépce 1826: Internal combustion engine: Samuel Morey 1827: Friction match: John Walker Andrew Jackson #7: 1830: Lawn mower: Edwin Beard Budding 1830: Stenotype on punched paper strip: Karl Drais 1831: Multiple coil magnet: Joseph Henry 1831: Magnetic acoustic telegraph: Joseph Henry (patented 1837) 1831: Reaper: Cyrus McCormick 1831: Electrical generator: Michael Faraday, Ányos Jedlik 1834: The Hansom cab is patented 1834: Louis Braille perfects his Braille system 1834: Refrigerator: Jacob Perkins
