Who is historically recognized as the 'Father of Forensic Toxicology' for publishing the first major scientific treatise on the detection of poisons and their effects on animals?
Mathieu Orfila
Mathieu Orfila published his treatise on poisons in 1814, establishing forensic toxicology as a legitimate scientific discipline.
Alphonse Bertillon developed a personal identification system in 1879 known as anthropometry. What was the primary basis of this system?
Taking a series of precise body measurements
Bertillon's anthropometry relied on taking specific morphological measurements of the human body (like head length, sitting height, etc.) to identify repeat offenders.
Which scientist undertook the first definitive study of fingerprints and developed a fundamental methodology for classifying them for filing?
Francis Galton
Francis Galton conducted the first comprehensive study of fingerprints and published the landmark book 'Finger Prints' in 1892, validating their use in personal identification.
Karl Landsteiner's major contribution to the forensic sciences was the discovery of:
The ABO blood typing system
In 1901, Karl Landsteiner discovered that human blood could be grouped into different categories (A, B, AB, and O), a foundational discovery for forensic serology.
Edmond Locard's famous Exchange Principle, a cornerstone of forensic science, asserts that:
Every contact leaves a trace
Locard's Exchange Principle states that when two objects come into contact with one another, there is a cross-transfer of materials (trace evidence).
Before the widespread adoption of fingerprinting, Bertillonage was the standard for criminal identification. Which of the following was NOT a typical measurement recorded in Bertillon's anthropometric system?
Iris pattern scanning
Iris pattern scanning is a modern biometric method. Bertillon's system relied entirely on skeletal/physical measurements of bone structures that would not change in an adult.
In his 1892 book Finger Prints, Francis Galton provided statistical proof supporting which key assertion about fingerprints?
They are unique to the individual and do not change over a lifetime
Galton demonstrated statistically the uniqueness of fingerprints and affirmed that an individual's prints remain unchanged from birth until decomposition.
In addition to formulating the Exchange Principle, Edmond Locard established one of the world's first police crime laboratories in 1910. In which city was this laboratory located?
Lyon, France
Locard began his first primitive police laboratory in an attic room at the police department in Lyon, France, fundamentally changing how evidence was analyzed.
Prior to the advent of DNA profiling, Karl Landsteiner's discovery of blood groups was primarily useful to criminal investigators because it allowed them to:
Exclude innocent suspects whose blood types did not match the crime scene evidence
Because blood typing is class evidence (many people share the same blood type), it cannot positively identify one specific person, but it is highly effective at excluding those with non-matching types.
Mathieu Orfila's groundbreaking work in 1814 focused on toxicology. Which specific methodology did his early treatises heavily detail to establish techniques for poison detection?
The physiological effects of poisons on animals
Orfila's systematic study involved administering various poisons to animals and closely observing their physiological effects and postmortem signs, thus establishing toxicology on a scientific basis.
