when was science first used to solve crimes
Forensic science James Marsh was the first to apply this new science to the art of forensics. He was called by the prosecution in a murder trial to give evidence as a chemist in 1832. The defendant, John Bodle, was accused of poisoning his grandfather with arsenic-laced coffee. Marsh performed the standard test by mixing a suspected sample with hydrogen sulfide and hydrochloric acid. While he was able to detect arsenic as yellow arsenic trisulfide, when it was shown to the jury it had deteriorated, allowing the suspect to be acquitted due to reasonable doubt.[25]
Wilhelm Wundt Wilhelm Maximilian Wundt (16 August 1832 â€“ 31 August 1920) was a German physician, physiologist, philosopher, and professor, known today as one of the founding figures of modern psychology. Wundt, who noted psychology as a science apart from philosophy and biology, was the first person ever to call himself a psychologist.[2] He is widely regarded as the "father of experimental psychology."[3][4] In 1879, Wundt founded the first formal laboratory for psychological research at the University of Leipzig. This marked psychology as an independent field of study.[5] By creating this laboratory he was able to establish psychology as a separate science from other topics. He also formed the first academic journal for psychological research, Philosophische Studien (from 1881 to 1902), set up to publish the Institute's research.[6]
