The evidence was literally “under their noses,” and several jurors fainted at the stench as Orfila conducted the chemical test inside the courtroom. 2014 Teen Biotech Challenge Sheldon High School Rachel Kan, Before the DNA double helix was even known, the nucleic acid part of DNA and RNA was discovered by a Swiss physician, Friedrich Miescher. Fauld used fingerprints to prove suspect innocent. His work refined forensics as a science. During this module, the following essential questions will be addressed: Pay attention to these key terms as you go through the lessons: Many people have contributed to this bed of knowledge of forensic science by publishing their findings and developing techniques. In large doses these compounds act as poisons that in the mid-1800s were almost impossible to identify. The defense's last gasp was to summon yet another expert witness, François Raspail, Orfila's bitter enemy, who had already jousted with him in a previous case. Someone was stabbed and all the knives in the village were collected. Often called the "Father of Toxicology," he was the first great 19th-century exponent of forensic medicine.

The dead man's widow, Marie Lafarge, was eventually convicted of poisoning her husband after a long and highly publicized trial. Important Contributions of Forensic Science Timeline created by ctaylor2004. The prosecution sought to build on this by introducing the findings of local doctors who performed chemical tests on Charles Lafarge's stomach and on the white powders that had been gathered as evidence. (Source: The Discovery of the Molecular Structure of DNA - The Double Helix), Scientists proposed DNA was the building block of genetics and discovered the varying amounts of the four nitrogenous bases; adenine, thymine, guanine, and cytosine. Marsh, Orfila, and Stas were pioneers of forensic science, particularly forensic chemistry. When was the concept of Forensic Science first noted? For his publication in Forensic Toxicology in the 19th century he is known as the Mathieu Orfila- father of toxicology Alphonse Bertillion-father of anthropometry Francis Galton- father of fingerprinting Calvin Goddard-father of ballistics Albert S.

Incorporated Gross' principles into a workable crime lab. In this video Dr. Saferstein discusses several important aspects of collecting evidence from a crime scene including the chain of custody, standard reference samples, and substrate controls. A transcript of the video is also available at this link. Witnesses had seen her buying arsenic—to exterminate rats, she claimed—and testified that she had stirred a white powder into her husband's food.
