  Latent fingerprints, Dr.Edmond Locard, the father of "Ridgeology"
Edmond Locard, a student of Bertillon, and the director of the laboratory at Lyon, France, established the first rules of the minimum number of minutiae necessary for identification
Locard also realized the value of the shape of the ridge as being permanent, and he should also be known as the father of Edgeoscopy.
In 1914, Dr. Locard published his conclusions of the fingerprint identification and the criteria that should be used to assure reliability based upon statistical analysis study.

 Trace Evidence: Hair by Kathy Steck-Flynn
Edmond Locard was the founder of the Institute of Criminalistics at the University of Lyon in France.
Locard believed that that when on person came in contact with another person or object a cross transfer of minute particles occurred.
Locard believed that crimes could be solved by inspecting the "dust particles" carried to and from a scene.

Poroscopy was established by Dr. Edmond Locard of Lyons, France in 1912.
Locard was of the opinion that friction ridges could be identified by comparing pores.
Locard suggested that identification could be based upon the size, shape, relative position and the frequency of the pores.

 Pores   (Site not responding. Last check: 2007-11-07)
Locard observed that like the ridge characteristics, the pores are also permanent, immutable and individual, and these are useful to establish the identity or otherwise of individuals when available ridges do not provide sufficient ridge characteristics.
Locard was born in France in 1877, and worked as the assistant of the great forensic pioneer Alexandre Lacassagne, who was at that time the Professor of Forensic Medicine at Lyons.
Locard was active in his research till his death in 1966.

Edmond Locard wrote that if 12 points (Galton's Details) were the same between two fingerprints, it would suffice as a positive identification.
Locard's 12 points seems to have been based on an unscientific "improvement" over the eleven anthropometric measurements (arm length, height, etc.) used to "identify" criminals before the adoption of fingerprints.
In 1924, an act of congress established the Identification Division of the F.B.I. The National Bureau and Leavenworth consolidated to form the nucleus of the F.B.I. fingerprint files.

It is impossible for the criminal to act without leaving traces, some which are so minute they need the most advanced scientific technology to detect.
The first person to formally state this principle was Dr. Edmond Locard.

 Ear Identification
The ear is, for each human being, so different that the precise description, with all its characteristic features would already be enough to ascertain the identification".
Edmond Locard in his book "L'identification des recidivistes": "This organ, that is a part of the face which in present day is the least looked at, can be considered as one of the most important for police science because it contains the most characteristic feature parts.
The ear has a double character, on the one side qua sizes and forms it is unchangeable from birth till death, and on the other appears to be so variated that it is allmost impossible to find two identical ears".

Today it is increasingly used in a wide variety of both criminal and civil cases involving comparison of samples associated with the crime scene to those associated with suspects.
Forensic science also owes a great debt to the French criminalist Edmond Locard, who worked for the French police in the years following 1910 and worked on many cases involving minerals.
He provided us with the Transfer Principle - that if two people or things come in contact, an exchange of materials takes place.

 Footwear, the Missed Evidence
Around 1910, a criminologist by the name of Edmond Locard arrived at a theory that every time something comes into contact with another it either takes or leaves a portion of itself or another.
This theory is called the Edmond Locard Theory, which simply states "Every contact leaves its trace." This theory is continually used today in crime scene investigations and the analysis of physical evidence.
Since criminals must enter and exit crime scene areas it should therefore, be reasonably assumed that they may leave traces of their footwear.

 Geoforensics - News & Resources
But, it may be a simple case of just matching soil, rocks, minerals, or fossils with a particular location or landforms with a particular time (i.e., the exchange of materials, as described above by Locard) that provides assistance to investigators and evidence in civil and criminal proceedings.
By acting as a third-party expert to provide independent technical analysis in disputes/mediation/arbitration/court actions, a forensic geologist has assisted in finding "common ground", win-win solutions, and/or alternative approaches when soil or water is a significant issue.
In the more than 70 years since Locard first formulated his exchange principle, investigators and scientists have applied the principle and other geologic concepts in developing evidence to support many types of court cases.

The first recorded use of science to solve a criminal case came in the mid-13th century.
However, many credit Frenchman Edmond Locard as being the father of modern forensics.
In the early years of the 20th century, Locard published his Principle of Exchange, which postulated that there is always an unintentional exchange of material between criminal and victim, and that this material can be used to determine the criminal's identity.

There is a principle in homicide investigation that refers to a theoretical exchange between two objects that have been in contact with one another.
This theory of transfer or exchange is based on Locard's "Exchange Principle." Edmond Locard, a Frenchman, who founded the University of Lyons' Institute of Criminalistics, believed that whenever two human beings came into contact, something from one was exchanged to the other, and vice-versa.
This exchange might involve, hairs, fibers, dirt, dust, blood and other bodily fluids, as well as skin cells, metallic residue and other microscopic materials.
