who discovered fingerprints?

As would be expected fingerprints have been around as long as man has, and thus the first human to look at their hands would have discovered fingerprints. I assume that in this question you are asking who realised that they could be used as a method of identification. This has been known for thousands of years, in fact in early civilisation the distinctive fingerprint of a person could be found on pottery created by that person as way of a hall mark.\nNehemiah Graw (1641-1712) was one of the first people to study the distinct ridges of the fingerprints, and the science of their study developed through such people as Marcello Malpighi and Thomas Bedwick. The first person to realise that fingerprints were so distinctive they could be used fairly accuratly as a means of identification was Sir William Herschel (1833-1917), but it was Dr Juan Vucetich who started up the worlds first fingerprint buereu in argentina, and this became the first country in 1896 to abolish athropometry as a means of identification, in favour of fingerprints.

Joseph Priestley is best known as the discoverer of oxygen.\nHe isolated 'depholgisticated 'air, or 'good air' in 1774. Our understanding today of the chemical reaction of oxygen comes from Antoine Lavoisier's systematic theory of combustion.\n\nToo bad contributors like the above 'opinion' can't use this forum as a means of increasing knowledge, rather than \ngiving silly answers in order to get points. Some never grow up i suppose.\nSource:www.woodrow.org./teachers/chemistry/institutes/priestley.

Robert Esnault-Pelterie would be most likely inventor if you wish to agree with the majority of researchers.\nFeel free to visit the source for information over the two mentioned inventors.

Using his/her fingerprints:\n\nFingerprint identification (sometimes referred to as dactyloscopy) is the process of comparing questioned and known friction skin ridge impressions (see Minutiae) from fingers, palms, and toes to determine if the impressions are from the same finger (or palm, toe, etc.). The flexibility of friction ridge skin means that no two finger or palm prints are ever exactly alike (never identical in every detail), even two impressions recorded immediately after each other. Fingerprint identification (also referred to as individualization) occurs when an expert (or an expert computer system operating under threshold scoring rules) determines that two friction ridge impressions originated from the same finger or palm (or toe, sole) to the exclusion of all others.

There are four basic patterns used to classify fingerprints -the arch, the loop and the whorl, and the composite (which is a combination of the arch, loop and whorl). If you think of a military map or a bushwalker's map, an "arch" is a gentle rise, a "loop" is a ridge, while a "whorl" is a solitary hill or peak.\nTo match one fingerprint to another fingerprint, the fingerprint officer has to find a certain number of recognisable features that are the same in each fingerprint - these are called similarities. In most countries, there have to be more than eight such similarities between the fingerprints, before they can be counted as admissible evidence.\n\nIdentical twins happen when a single fertilized egg splits into two embryos. Each of the embryos has identical DNA, so surely the new-born babies should greet the world with identical fingerprints?\nFingerprints are laid down between the 13th and the 19th week of growth in the womb. There are at least two factors that can give different fingerprints.\n\nFirst, the DNA doesn't make a perfect copy of itself every time it divides - it picks up mutations. To get from one single cell to the 10-100 trillion cells of a grown adult human, the DNA has to divide many many times. This gives ample opportunity for many mutations to accumulate.\nSecond, the mathematicians tell us that if the foetus had flattened finger pads, the baby is more likely to have the simpler arch pattern, or the slightly more complicated loop pattern. But on the other hand, if the foetus had swollen finger pads, baby is more likely to have the more complex whorl pattern of ridges. The two identical twins might grow in the same uterus, but they have different lengths and diameters of umbilical cord, so they will each get a different blood flow. The twin with the lesser blood flow will cut down the blood flow to the lower body, to preserve it for the brain. By an accident of anatomy, this gives more blood flowing into the arms. The baby ends up with proportionately bigger fingers, and more whorls in their fingerprints.\n\nIn 2003, a paper called On the similarity of identical twin fingerprints was published in The Journal of the Pattern Recognition Society. They found that the fingerprints of 94 "identical" twins were not identical - although they were more similar than non-related people. \nVarious organisations collect fingerprints, but the FBI probably has the biggest collection. They have over 200 million sets of fingerprints - but then, so does every house with small children!

The first Japanese latent print examiner to use cyanoacrylate fuming to intentionally develop fingerprints was Masato Soba at the Saga Prefectural Crime Laboratory of the National Police Agency of Japan.  Mr. Soba learned of the development of superglue fingerprints from co-worker Fuseo Matsumura... a hair and fiber expert who discovered his own fingerprints developing on microscope slides while mounting hairs with cyanoacrylate. The hairs were from a case involving a murdered taxi cab driver.

Humphrey Microscope.\n\nSeriously, it's usually credited to Leewenhoek.

Ninhydrin is a chemical used to reveal latent fingerprints.  It reacts with ammonia and the organic amine functional group that are found in fingerprint residues.

sir isaac newton. the man who "discovered" the law of gravity.

Watson and Crick discovered it while researching "genetic material." For further information, check this site.

I would say Watson and Crick.  They discovered DNA, leading the biological world into a whole new era that makes so much possible from treating deadly diseases to cloning.

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

He invented the polygraph (lie detector).  There's lots information on him on the web.  Use the search terms Larson and polygraph.

The first person I thought of was Gregor Mendel, but everyone already pretty much knew that plants were alive already, he just showed that they have genetics.

It was a Brittish scientist and unfortanately I can't remember his name. It was used as evidence the first time in a murder trail in England where two girls were found dead in a path near a field. The new science of Dna helped to prove whom the killer was. I even read the book about the murder investigation and the scientist but me with my middleage brain can not remember it's name either. Maybe someone out there can remember the name of the scientist or the  name of the book. Sorry I could not be of more help. But maybe this will put you on the right track

You have to start with Anton van Leeuwenhoek. This Dutchman was the first man to use a microscope to view water and saw the small animals living there. He is called the father of microbiology according to wikipedia.
