Charles Gabriel Pravaz (1791-1853), French surgeon, and Alexander Wood (1817-1884), Scottish physician, independently invented the hypodermic syringe. It is first used to inject morphine as a painkiller

The first match was made by Robert Boyle around 1680, and scientists and inventors have been improving them ever since.\n\nCheck out the website I've attached.  I hope this helps.

Vaccination: Physician Edward Jenner performed the first innoculation against smallpox by infecting a boy with cowpox (vaccinia virus) in 1796.\n\nLight bulb: In 1879 in America Thomas Alva Edison, and in England Joseph Swan, each produce carbon-thread electric lamps that can burn for practical lengths of time (about 40 hours).

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.

In 1928, Scottish scientist Alexander Fleming. \n\nHe was trying to grow bacteria, bu tHe found that in the vessel that had penicilin, all the bacteria are dead, he tested it several times and finally he found the anti-bacterial power in penicillin. [Most probably he recvd Noble prize for this]\n\nSince then, the mankind is endowed with yet another strong weapon to fight bacteria.\n\nSay thanks to Flemming!

Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published. Antonie Lavoisier, a French chemist, also discovered oxygen in 1775, was the first to recognize it as an element, and coined its name "oxygen"

Benjamin Franklin but a lot of scientists contributed in the discovery. It all started 600 BC with the greeks followed by Dr William Gilbert,Benjamin Franklin,Galvani and Volta,Michael Faraday,Thomas Edison and Joseph Swan,George Westinghouse and Nikola Tesla,James Watt and finally Andre Ampere and George Ohm

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

All previous answers are wrong. Aristotle is credited with being the first scientist, because he used observation rather than unverifiable references. Mind you, the progress was halting. Even he still detected "anima" in frogs, as some sort of soul. The whole concept of purely using observation had not really sunk in. However, he is generally credited...\n\n\nSupport novel transit solutions: http://www.hallisystem.bravehost.com
