Discovery of Fingerprints – Casa & Asa Discoveries & Inventions for Kids| Educational Videos| Mocomi

Discovery of Fingerprints Asa : What is that? Casa : That is a handprint! Our ancestors used hand prints as signatures
before they learned how to read and write. Asa : Ee! Ee! Wow! Really? Casa : Yes! It is still used as the only authentic identification
tool we have, in this age of biometric identification too! Asa: How did people know that fingerprints
are unique? Casa: Come let’s see. In 1858, William Herschel, a British civil
servant who worked in India asked a local builder to sign a contract with a palm print
of his entire hand, because the man didn’t know how to sign his own name. Asa: And then? Casa: Then Herschel noticed the uniqueness
of the lines in the print. Fascinated, he began collecting fingerprints
of everyone he came into contact with. This allowed him to discover that every fingerprint
was unique. Asa: Wow! Casa: But his approach was not very scientific,
let’s see who took a more scientific approach. In late 1870s Dr. Henry Faulds, a British
surgeon-superintendent stationed in Tokyo, Japan, discovered imprints in ancient pottery
shards and became interested in the science of human fingerprints. Asa: So, he is the one who scientifically
proved that fingerprints are unique? Casa: Smart dino! He is also credited with the first fingerprint
identification of a greasy fingerprint left on a bottle. Asa: Cool, now let’s play Sherlock. I’ll be Sherlock, you be Holmes. Ee! Ee! Casa: Huh?
