In 1852 fingerprinting was first used simply on contracts to look at them and the patterns they made. They weren't studied for scientific beliefs, but for superstitious beliefs. But soon a man named Sir William James Herschel connected the fact that you can prove or disprove identity with fingerprints.
Since then, there have been discoveries through ink impressions. People have even signed papers with their names along with a thumb print to prevent forgery. Then Alphonse Bertillon came along and said that fingerprints could measure how big your hand is and how long your arm is. However, this was proven that is couldn't necessarily always work.
Now fingerprints are still used to this day to solve crimes, identify criminals, and record data. They play an important role in science and the rest of society.
