He was a very busy man. He moved to Japan to help people. He ran a large hospital in Tokyo. His hospital treated 15,000 patients every year. He also helped start a school for the blind. He even helped stop a disease that killed fish.

One day, Henry saw marks on old clay. He looked at his own fingertips. He saw tiny lines on his skin. He thought these lines were unique. This means no two people have the same lines.

Later, someone broke into his hospital. The police arrested a worker. Henry thought the man was innocent. He compared the finger marks at the scene to the worker's fingers. The marks were different. Because of this, the police let the man go.

Henry wrote about this in a science journal. He wanted the world to use this way to find people. He had many arguments about who first thought of this. He felt he did not get enough credit. He died in 1930 at age 86. Today, people remember his great work.
