"Bacteria were first observed by Anton van Leeuwenhoek in 1676 using a single-lens microscope of his own design. The name "bacterium" was introduced much later, by Ehrenberg in 1828, derived from the Greek word βακτηριον meaning "small stick". While Antony van Leeuwenhoek is often cited as the first microbiologist, the first recorded microbiological observation, that of the fruiting bodies of molds, was made earlier in 1665 by Robert Hooke. The field of bacteriology (later a subdiscipline of microbiology) is generally considered to have been founded by Ferdinand Cohn (1828-1898), a botanist whose studies on algae and photosynthetic bacteria led him to describe several bacteria including Bacillus and Beggiatoa. Cohn was also the first to formulate a scheme for the taxonomic classification of bacteria. Louis Pasteur (1822-1895) and Robert Koch (1843-1910) were contemporaries of Cohn’s and are often considered to be the founders of medical microbiology. Louis Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation, thereby solidifying microbiology’s identity as a biological science. Pasteur also designed methods for food preservation (pasteurization) and vaccines against several diseases such as anthrax, fowl cholera and rabies. Robert Koch is best known for his contributions to the germ theory of disease, proving that specific diseases were caused specific pathogenic microorganisms by the application of what has become known as the Koch's postulates. Koch was one of the first scientists to focus on the isolation of bacteria in pure culture resulting in his description of several novel bacteria including Mycobacterium tuberculosis, the causative agent of tuberculosis. While Louis Pasteur and Robert Koch are often considered the founders of microbiology, their work did not accurately reflect the true diversity of the microbial world because of their exclusive focus on microorganisms having medical relevance. It was not until the work of Martinus Beijerinck (1851-1931) and Sergei Winogradsky (1856-1953), the founders of “general microbiology” (an older term encompassing aspects of microbial physiology, diversity and ecology), that the true breadth of microbiology was revealed. Martinus Beijerinck made two major contributions to microbiology: the discovery of viruses and the development of enrichment culture techniques. While his work on the Tobacco Mosaic Virus established the basic principles of virology, it was his development of enrichment culturing that had the most immediate impact on microbiology by allowing for the cultivation of a wide range of microbes with wildly different physiologies. Sergei Winogradsky was the first to develop the concept of chemolithotrophy and to thereby reveal the essential role played by microorganisms in geochemical processes. He was responsible for the first isolation and description of both nitrifying and nitrogen-fixing bacteria."

Pasteur, he was a virologist who not only invented pastuerization but discovered many things about bacteria that are still in use today.  Google him.

Many different ones. For instance, the structure of DNA was figured out thanks to x-ray crystallography\n\nProbably the most famous X-ray diffraction image is the photograph of the B form of DNA taken by Rosalind Franklin in May 1952 ( http://www.physicstoday.org/vol-56/iss-3/captions/p42cap3.html ). With the help of Oxford crystallographer Dorothy Hodgkin, Franklin described the helical backbone and correct crystallographic space group for DNA . Her work was instrumental in Watson's and Crick's correct modeling of DNA, for which they received the Nobel Prize.

Leonardo da Vinci.  Not a scientist, per se, but he did explore scientific thought and was a remarkable engineer and inventor.  Fascinating guy.

While, indeed, Michał Sędziwój first wrote about oxygen. \n\n A Swedish person named Carl Wilhelm Scheele was a little more scientific in his description and used scientific methods. But, he did not published his findings until after the discovery of Oxygen by Joseph Priestley. Priestley published his discovery, consequently Priestley is usually given the credit.\n\nGet an "A".

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases. Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information. He even suggested DNA might actually be the gene. Most people at the time thought the gene would be protein, not nucleic acid, but by the late 1940s, DNA was largely accepted as the genetic molecule. Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked.\n\nIn 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix, spiraled like a spring coil. In 1950, biochemist Erwin Chargaff found that the arrangement of nitrogen bases in DNA varied widely, but the amount of certain bases always occurred in a one-to-one ratio. These discoveries were an important foundation for the later description of DNA.\n\nIn the early 1950s, the race to discover DNA was on. At Cambridge University, graduate student Francis Crick and research fellow James Watson (b. 1928) had become interested, impressed especially by Pauling's work. Meanwhile at King's College in London, Maurice Wilkins (b. 1916) and Rosalind Franklin were also studying DNA. The Cambridge team's approach was to make physical models to narrow down the possibilities and eventually create an accurate picture of the molecule. The King's team took an experimental approach, looking particularly at x-ray diffraction images of DNA.

1986-In the first use of DNA to solve a crime, Jeffreys used DNA profiling to identify Colin Pitchfork as the murderer of two young girls in the English Midlands. Significantly, in the course of the investigation, DNA was first used to exonerate an innocent suspect.\n\n1987-DNA profiling was introduced for the first time in a U.S. criminal court. Based on RFLP analysis performed by Lifecodes, Tommy Lee Andrews was convicted of a series of sexual assaults in Orlando, Florida.\n\nhope this helps

History of Mitochondria\nDiscovered by a scientist named Altmann in 1890: called them “bioblasts” •Altmann suggested they might be tiny independent organism within living cells.\nMITOCHONDRIA was then named by scientist Benda.

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

How about Madame Curie...would that be helpful? I was going to suggest Charles Darwin, but noticed someone already answered...

Linus Pauling - Structure of polypepeptides, and before Watson and Cricks stroke of genius, was working on elucidating the structure of DNA (he proposed a triple helix with nitrogenous bases on the periphary).\n\nFred Sanger - Developed the currently preffered chain terminator method of DNA sequencing in 1975\n\nSidney Brenner - Nobel Laureate 2002, dscovered mRNA in 1960, but is more famous for his work on development in nematods, especially in establishinng how Apoptosis (programmed cell death) is important in determining cell fate

Darwin did just about everything, much more than just evolution. He also discovered how an atolls were formed. Gregor Mendel for genetics, Watsin and Crick for DNA, Coriolis, for the coriolis effect. If you really need to know this now, why not look it up yourself?

that question ranks with who discovered u can get milk from cows and what they were doing at the time lol
