How was the first fingerprint found?

The first fingerprint was identified in 1892 by Sir Francis Galton, a British scientist who studied the unique patterns and characteristics of fingerprints. He published a book detailing his findings on fingerprint patterns and their uniqueness for identification purposes. Galton's work laid the foundation for the use of fingerprints in forensic science, leading to their adoption in criminal investigations. The first criminal case solved using fingerprints occurred in 1901, when they were used to confirm the identity of a suspect in a murder case in Argentina.
