He invented a "photophone", the predecessor to our fiber optics.  It was a way to transmit information, in the form of sound, over light. In addition, he invented a vacuum jacket that would eventually become the iron lung used in polio cases in the 50s.  He also pioneered into the area of desalinization, "alternative energies" and recycling.  He also invented the concept of metal detectors, using an inductive pickup coil.

The quote is actually - "Genius is 1% Inspiration and 99% perspiration", and it was quoted by Thomas Alva Edison the most famous American Inventor who, singly or jointly, held a world record 1.093 patents. In addition, he created the world's first industrial research laboratory, 1847-1931.

At the 1893 World's Fair, the World's Columbian Exposition in Chicago, an international exposition was held which for the first time devoted a building to electrical exhibits. It was a historic event as Tesla and George Westinghouse introduced visitors to AC power by using it to illuminate the Exposition. On display were Tesla's fluorescent lights and single node bulbs. Tesla also explained the principles of the rotating magnetic field and induction motor by demonstrating how to make an egg made of copper stand on end in his demonstration of the device he constructed known as the "Egg of Columbus".

If you gave it your best shot then you didn't really fail. You'd only be a failure if you were too much of a coward to have made the effort in the first place.\n\n\n*Thomas Edison took 2000 tries to invent the lightbulb - when he was asked 'how did it feel to 'fail' 2000 times he just laughed and said:\n\n'I didn't fail I invented the lightbulb. It just so happens that it was a 2000 step process!'.\n\nPick yourself up, dust yourself down and try again

C. tetani was first discovered by Arthur Nicolaier in 1884 and isolated by Shibasabura Kitsato (Japan) in 1889. The first treatment was the tetanus antitoxin, developed in Germany by Emil von Behring, who received the first Nobel Prize for Medicine, and later at the New York City Health Department. The tetanus toxoid, which induces active immunity, was developed at the Pasteur Institute in 1923. Interestingly, the incidence of tetanus in New York City decreased dramatically between 1900 and 1930, not because of the use of the antitoxin but because of the decrease in the number of horses in the city following the introduction of the automobile. Persons receiving wounds were less likely to have them contaminated by horse droppings, a rich source of C. tetani spores. The conception that tetanus results from rusty nails probably originates from the close association of rusty nails, barns and horses, common before the early 20th century. In WWII, American forces only suffered 16 cases of tetanus and 6 deaths, thanks to routine tetanus toxoid immunization. The German army used only the antitoxin and suffered much higher losses due to tetanus. Use of the toxoid was restricted to the Luftwaffe, the German air force.

There was a vaccine until about Spring 2002.  It was called LYMErix but was discontinued due to very low sales and possible ineffectiveness.  I guess it wasn't popular enough with doctors!

There seems to be some confusion about whether the person who invented traffic lights was either Garrett Augustus Morgan or William L. Potts.  See http://www33.brinkster.com/iiiii/trfclt/ for more information on that.\n\nHere are some other websites that might help you with your question.\nhttp://www.didyouknow.cd/trafficlights.htm\nhttp://www.blackseek.com/bh/2001/165_GMorgan.htm\nhttp://www.ideafinder.com/history/inventions/trafficlight.htm\n\nHope this helps.

The invention of the laser, which stands for light amplification by stimulated emission of radiation, can be dated to 1958 with the publication of the scientific paper, Infrared and Optical Masers, by Arthur L. Schawlow, then a Bell Labs researcher, and Charles H. Townes, a consultant to Bell Labs. That paper, published in Physical Review, the journal of the American Physical Society

The vacuum flask was invented by the Scot Sir James Dewar, while working as a scientist at Oxford University in 1892.\n\nThe first barometer was devised by Evangelista Torricelli, a student of Galileo Galilei, in 1643.\n\nThe best known safety lamps are the Davy lamp, invented by Sir Humphry Davy and the Geordie lamp, invented by George Stephenson. Both of those were invented in 1815 and have been superseded by the Gray, Muesler, Marsant, and other lamps; most later lamps are constructed on the principle discovered by Davy, that a flame enveloped in wire gauze of a certain fineness does not ignite firedamp.

"Thomas Edison tried and failed nearly 2000 times to develop the carbonized cotton thread filiment for the incandescent light bulb.  When asked about it, he said, 'I didn't fail. I found out 2000 ways how not to make a light bulb.'  But he only needed to find one way to make it work."\n\nFrom National Treasure

it was edward jenner. but will u be satisfied with tht? i think i can tell u more...\n\nSmallpox is a viral disease characterized by a skin rash and a high death rate.\nOverview, Causes, & Risk Factors\n\nSmallpox was once found throughout the world, causing illness and death wherever it occurred. Smallpox was primarily a disease of children and young adults, with family members often infecting each other.\n\nA massive program by the World Health Organization (WHO) eradicated all known smallpox viruses from the world in 1977, except for samples that were saved by various governments for research purposes. The vaccine was discontinued in the United States in 1972. In 1980, WHO recommended that all countries stop vaccinating for smallpox.\n\nIn 1980, WHO also recommended that the remaining virus samples be transferred to two WHO laboratories for storage. Those laboratories were the Centers for Disease Control (CDC) in Atlanta, Georgia, and a laboratory in Russia. Russia, however, started a program to produce the smallpox virus in mass quantities, specifically for bombs and other weaponry.\n\nSome believe that other countries such as Iraq, Iran, and North Korea may also hold some stores of the smallpox virus. Researchers continue to debate whether or not to kill the last remaining samples of the virus, or to preserve it in case there may be some future reason to study it.\n\nAccording to the CDC, since the vaccine has not been administered in the U.S. since 1972, those persons who had received the vaccine in the past are likely susceptible now (as are those who have never been vaccinated). It is not known how long previous vaccinations would remain effective, but it is unlikely that people would still have a high enough level of immunity to protect against the virus.\n\nRisk factors for smallpox include being a laboratory worker who handles the virus (rare), or being in the environment where the virus was released as a biological weapon.\n\nTHE RISK OF TERRORISM\n\nIt is conceivable that smallpox could be deliberately reintroduced into the population. Smallpox could be released by aerosol, and it would spread easily because the virus remains very stable in aerosol form.\n\nIt would take no more than 50-100 cases to cause legitimate concern on an international level. Emergency measures would need to be taken immediately.\n\nSmallpox is highly contagious from one person to another. It is most contagious during the first week, and is spread from saliva droplets. It may continue to be contagious until the scabs from the rash fall off. It may also be spread from bed sheets and clothing.\n\nResearchers believe that the smallpox infection (if released in aerosol form, under favorable conditions, without sunlight) could remain viable for as long as 24 hours. In unfavorable conditions, the virus may only remain viable for 6 hours. There is clear evidence that shows that the virus can remain viable on bed linens and clothes for significant periods of time.\nSmallpox Symptoms & Signs\n\nSmallpox has two forms: 1) Variola major -- which is a serious illness with a mortality rate according to the CDC of 30% or more, in unvaccinated people, and 2) Variola minor -- a milder infection with a mortality rate of less than 1%. The incubation period for smallpox is approximately 12-14 days. The symptoms are:\n\nHigh fever \nFatigue \nSevere headache \nBackache \nMalaise \nRash, raised and pink on the skin, starting centrally and spreading outwards. (First the mucosa of the mouth and throat, then face, forearms, trunk, and legs. Rash turns to pus-filled lesions that become crusty on the eighth or ninth day.) \nDelirium \nVomiting and diarrhea \nExcessive bleeding \n\nSmallpox Prevention\n\nMany people were vaccinated for smallpox in the past -- but the vaccination is no longer given because the virus has been eradicated. According to the CDC, the United States has supply of the smallpox vaccine sufficient for the entire population at this time.\n\nThe
