As the website above stated, fingerprints were once used as seals on clay tablets for bussiness transactions. During the 14th Century they were also used on some government papers. Near that time a doctor/government official discovered that no two fingerprints were identical. Through the years various people discovered/studied fingerprints and eventually found the different patterns. It was not until the 1880's that Dr. Henry Faulds, a British surgeon-Superintendent, discovered the use of fingerprints as a way to identify a person.
