There are more and more English and American crime drama TV shows. Each of them talks about murder. For every murder the team is in charge of finding the cause of the death, as well as the murderer. To discover this, it is necessary to make DNA’s test in laboratory etc... Through these series the public is more and more interested in the science of the crimes (murders), etc... Chemistry played a large part in the criminal researches and for the police scientists, in particular with the discovery of the DNA, in 1953. But all this started well before. Exactly in the 1850s, when the living conditions were very difficult and where the crimes were many. The writer Sir Arthur Ignatus Conan Doyle, was one of the first to hint at science and more exactly at chemistry in the police. Indeed, in one his novels about it who stages the detective Sherlock Holmes he speaks. Conan Doyle was inspired by real English living conditions to write his novel. In it, Sherlock Holmes uses some hydrogen peroxide which allows to spot the blood. The hydrogen peroxide in this time is, in fact the equivalent of luminol in the 21th century, which is used on crime scenes. We see this technique appearing in English and American series. For example in the series CSI which stages a police team, solving murders.
We shall there come thus to wonder: to what extent the scientific researches of Sherlock Holmes have allowed the evolution of the detection of the blood?
At first we shall tilt us on the context of Jack the ripper, in particular during the Victorian era, the poverty and the bad living condition of the majority of the population urbanization and industrialization, the degradation of the society, Jack the ripper and the others criminals, then we shall speak about Sherlock Holmes and the hydrogen peroxide in particular the English literature, the discovery of the hydrogen peroxide and the chemistry (test, positive forgery), we shall continue with the luminol and the current English series with: the luminol, the series and the chemiluminescence.
