Inventors & Inventions

    1. Peace SymbolThe Direct Action Committee, a group pushing for nuclear disarmament, invented the peace symbol in 1958. The forked symbol is actually a composite of the semaphore signals "N" and "D," to stand for nuclear disarmament.
    2. Ivory bar soap floating was a mistake. They had been over mixing the soap formula causing excess air bubbles that made it float.Customers wrote and told how much they loved that it floated,and it has floated ever since. [It floats in gasoline, too.]
    3. Fortune cookies were invented in San Fransisco around 1914. In 1983 a judge decided that the modern fortune cookie came from San Fransisco. Source

Mrs. Behrman sold the company to several New York investors in 1988, two years before she died at age 95. But America's first and only remaining doll manufacturer has not compromised her high standard of quality and unique craftsmanship. Today, most of the company's manufacturing is still done in Harlem, New York, and more than 500,000 dolls a year are sold.

  9. The 'spot' on 7UP comes from its inventor who  had red eyes. He was albino.
  10. Edison improved the incandescent lamp in 1879,  but he didn't actually invent it. Sir Humphrey  Davy is reputed to be the true inventor of the  electric light. He passed electricity through a  platinum wire and caused an arc lamp to glow as  early as 1802. However, Davy did not pursue the  discovery. By the time Edison entered the  scene, arc lamps had been burning for several  decades, but were limited by short life spans.  Edison developed a long-lasting filament light  in 1877, and in 1879 produced the first  long-lasting light bulb.
  11. The man who invented shorthand, John Gregg, was  deaf.
  12. Because he felt such an important tool should  be public property, English chemist John Walker  never patented his invention — matches.

  17. Pez was invented in 1927 by Eduard Haas, an  Austrian anti-smoking fanatic, who marketed  peppermint-flavored PEZ as a cigarette  substitute. The candy gets its name from the  German word for peppermint, Pfefferminze. Haas  brought the candy to the U.S. in 1952. It  bombed, so he reintroduced it as a children's  toy, complete with cartoon heads and fruity  flavors. One of the most secretive companies in  the U.S., PEZ won't even disclose who currently  owns the company.
  18. The Nobel Prize resulted from a late change in  the will of Alfred Nobel, who did not want to  be remembered after his death as a propagator  of violence - he invented dynamite.
  19. Alfred Nobel usdog powered ed a cellulose adhesive (nitrocellulose) as the chemical binder for nitroglycerin, which he used in his invention of dynamite.
  20. Germany holds the title for most independent  inventors to apply for patents.
  21. Noxema, the skin cream invented in 1914 by  Baltimore pharmacist George Bunting, was  originally sold as "Dr. Bunting's Sunburn  Remedy." Mr. Bunting changed the name to Noxema  after a customer enthusiastically told him the  cream had "knocked out his eczema." Thus, the  cream that "knocks eczema" became "Noxema".
  22. George Eastman, inventor of the Kodak camera,  hated having his picture taken.
  23. Root Beer was invented in Biloxi, Mississippi,  in 1898 by Edward Adolf Barq, Sr.
  24. Because Napoleon believed that armies marched  on their stomachs, he offered a prize in 1795  for a practical way of preserving food. The  prize was won by a French inventor, Nicholas  Appert. What he devised was canning. It was the  beginning of the canned food industry of today.
  25. Bavarian immigrant Charles August Fey invented  the first three-reel automatic payout slot  machine, the Liberty Bell, in San Francisco in  1899.
  26. More than 5,000 years ago, the Chinese discovered how to make silk from silkworm cocoons. For about 3,000 years, the Chinese kept this discovery a secret. Because poor people could not afford real silk, they tried to make other cloth look silky. Women would beat on cotton with sticks to soften the fibers. Then they rubbed it against a big stone to make it shiny. The shiny cotton was called "chintz." Because chintz was a cheaper copy of silk, calling something "chintzy" means it is cheap and not of good quality.
  27. Incan soldiers invented the process of freeze-drying food. The process was primitive but effective — potatoes would be left outside to freeze overnight, then thawed and stomped on to remove excess water.
  28. The first wooden shoe comes from the Netherlands. The Netherlands have many seas so people wanted a shoe that kept their feet dry while working outside. The shoes were called klompen and they had been cut of one single piece of wood.
  29. Today the klompen are the favorite souvenir for people who visit the Netherlands.

  56. The waffle iron was invented August 24, 1869.
  57. The alarm clock was not invented by the Marquis  de Sade, as some suspect, but rather by a man  named Levi Hutchins of Concord, New Hampshire,  in 1787. Perversity, though, characterized his  invention from the beginning. The alarm on his  clock could ring only at 4 am.

  71. The first known item made from aluminum was a rattle—made for Napoleon III in the 1850s. Napoleon also provided his most honored guests with knives and forks made of pure aluminum. At the time the newly discovered metal was so rare, it was considered more valuable than gold.
  72. Hale's 100 inch lens built in the early 1900s was the largest solid piece of glass made until then. The lens was made by a French specialist who poured the equivalent of ten thousand melted champagne bottles into a mold packed with heat maintaining manure so that the glass would cool slowly and not crack.
  73. When Alexander Graham Bell Was working on the telephone in 1876, he spilled battery acid on his pants and called out to his assistant, "Watson, please come here. I want you." Watson, who was on another floor, heard the call through the instrument he was hooking up, and ran to Bell's room. Bell's words became the first ever successfully communicated using a telephone.
  74. Dutch engineers have developed a computerized  machine that allows a cow to milk itself. Each  cow in the herd has a computer chip in its  collar. If the computer senses that the cow has  not been milked in a given period of time, the  milk-laden animal is allowed to enter the  stall. The robot sensors locate the teats,  apply the vacuum devices, and the cow is  milked. The machine costs a mere $250,000 and  is said to boost milk production by 15%.
  75. Out of the 11 original patents made by Nikola  Tessla, for the generation of hydroelectric  energy, 9 are still in use, (unchanged) today.
  76. The windmill originated in Iran in AD 644. It  was used to grind grain.
  77. Russian submarine designers are building  military submarines out of concrete. Because  concrete becomes stronger under high pressure,  (C-subs) could settle down to the bottom in  very deep water and wait for enemy ships to  pass overhead.

  93. In the year 1886, Herman Hollerith had the idea of using punched cards to keep and transport information, a technology used up to the late 1970's. This device was constructed to allow the 1890 census to be tabulated. In 1896 the Tabulating Machine Company was founded by Hollerith. Twenty-eight years later, in 1924, after several take-overs the company became known as International Business Machines (IBM).
  94. Spiral staircases in medieval castles are running clockwise. This is because all knights used to be right-handed. When the intruding army would climb the stairs they would not be able to use their right hand which was holding the sword because of the difficulties of climbing the stairs. Left-handed knights would have had no troubles, except left-handed people could never become knights because it was assumed that they were descendants of the devil.

Patrie, a Stanford graduate student invented the Watercolor Intelligent Nightlight, which informs bleary-eyed midnight bathroom-goers whether the toilet seat is up or down... without turning on a blinding light. Patrie introduced the device in the early 1990's. He explained, "When you get within five feet of the dark commode, it will sense your motion. It looks to see if the room is dark. Then it looks upward by sending out an infrared beam. If it gets a reflection, it knows the seat is up. If it is, the red light comes on."
  112. On the first neon sign, the word neon was spelled out in red by Dr. Perley G. Nutting, 15 years before neon signs became widely used commercially.

  120. An Englishman invented Scotland's national dress  - the kilt. It was developed from the philamore -  a massive piece of tartan worn with a belt and  draped over the shoulder - by English  industrialist Thomas Rawlinson who ran a foundry  at Lochaber, Scotland in the early 1700s and  thought a detachable garment would make life more  comfortable for his workers.
  121. It is recorded that the Babylonians were making  soap around 2800 B.C. and that it was known to  the Phoenicians around 600 B.C.

In his spare time, he had compressed a synthetic rubber material under 3,500 pounds of pressure per square inch, and eventually created the remarkable ball. It had a resiliency of 92 percent, about three times that of a tennis ball, and could bounce for long periods. It was reported that presidential aide McGeorge Bundy had five dozen Super Balls® shipped to the White House for the amusement of staffers.
  128. At a glance, the Celsius scale makes more sense than the Fahrenheit scale for temperature measuring. But its creator, Anders Celsius, was an oddball scientist. When he first developed his scale, he made freezing 100 degrees and boiling 0 degrees, or upside down. No one dared point this out to him, so fellow scientists waited until Celsius died to change the scale.
  129. At a jet plane's speed of 1,000 km (620mi) per hour, the length of the plane becomes one atom shorter than its original length.
