A. Once upon a time . . . 2000 years ago . . .  --Chinese artisans and scribes marked

their work by leaving fingerprint in clay

I. History of Fingerprints

Page 3: Unit 3: Fingerprints Part 1

B. Late 1600s--Nehemiah Grew = first scientist to describe fingerprint ridges

 C. Late 1800s . . . dactyloscopy begins to emerge  1. Sir William Herschel  

a. credited as the first to recognize the value of fingerprints in personal identification (unique)

b. periodically took his own fingerprints over 50 years and showed consistency in ridge patterns2. Henry Faulds . . . observed the same ideas at around the same time

D. Late 1800s . . . anthropometry takes center stage

1. need for a method of criminal identification and classification is great

Page 6: Unit 3: Fingerprints Part 1

2. 1881 Alphonse Bertillon develops bertillonage as means of identification

  a. system became widely accepted

  b. system based on anthropometry = the study of human body measurements

  c. system included 11

measurements

Page 7: Unit 3: Fingerprints Part 1

d. system laid a foundation for eventual acceptance of fingerprints as scientific method of personal ID . . . Why? Will West case points to fingerprints

E. 1892-1893 

1. Sir Francis Galton publish book, “Finger Prints”

 2. Many places add fingerprints to Bertillonage measurements

Page 9: Unit 3: Fingerprints Part 1

F. 1899 Henry system  1. Sir Edward Henry develops Henry system

of fingerprint identification2. Classification system based on having all 10 prints

(10-print cards filed)

Page 10: Unit 3: Fingerprints Part 1

G. 1901 Bertillonage system abandoned

H. Now have AFIS (computerized database of fingerprints)
