France, 1840: A 24-year-old woman named Marie Lafarge was charged with poisoning her husband. She had been seen buying arsenic "to kill her rats" and it was also rumored that she was unhappy with her marriage. Lawyers on both sides were arguing and the methods scientists used to prove that Lafarge had killed her husband kept being doubted or disproved. Both sides agreed to consult Mathieu Orfila, "Father of Toxicology." Orfila took samples from the husband's body and the soil that he was buried in. Orfila found traces of arsenic in the body and proved that it did not come from the surrounding soil, making the jury decide that Lafarge was guilty and she was sentenced to life in jail.
