Background
Henry Templeman attended the University of Bordeaux in France, the Goethe Institute in Radolfzell, Germany, the University of California Los Angeles, the College of San Mateo, Chabot College, and Hayward State University with major studies in foreign language, physics, chemistry and mathematics. In 1976 he worked at the Goetheanum in Dornach, Switzerland, where he studied the work of of Rudolf Steiner, and was introduced to the Golden Ratio, which he subsequently used to define and measure Golden Funnels in fingerprints.
In 2007 Henry Templeman attended a Ridgeology class by David Ashbaugh and was introduced to the idea that "sufficiency to establish positive fingerprint identification should exceed the largest and best fingerprint look-alike ever seen" and that "aggregate values for ridge features are determined by multiplying, and not adding, values for independent ridge features". Following Pat Wertheim's question "How do you define the largest and best look-alike ever seen?", Templeman worked for nearly 2 years conducting research and experimentation to find the best answer to that question based on classic scientific methodology as defined by Richard Feynman and Karl Popper.
With information gained as a result from experimentation, extrapolation from previous experiments, research and discussions with fingerprint experts and forensic scientists around the world, Henry Templeman completed and published online the first version of his “T Model” on August 16, 2008. Similar to the workings of a "1908 Ford Model T" automobile, Templeman's fingerprint match probability T Model is in it's infancy. Templeman compares his fingerprint model to a primitive caveman's club, however based on validation studies and experimentation, it has nevertheless shown to be more accurate than human fingerprint expert intuition (see Validation Study).
Since online publication, Templeman's T-Model has undergone updates and continues to be refined as the results from new, broader experiments are obtained. Like all scientific theories, the T-Model continues to undergo experimentation and validation study, and remains freely available to the scientific community for download, translation, peer review and falsification testing.
As of this writing, Henry Templeman's T-Model has received corroboration and has not been falsified by independent experiment.
"Experiment is the key that defines what is the best estimate for what is the largest and best fingerprint look-alike ever seen and what is the best estimate for "fingerprint match probability". Absent prior knowledge for the occurrence of an event, experiment is the key that defines what is the best estimate. Therefore, the more experiments you do, the better are your estimates."
