Dr. Schumann

Dr. Schumann was a doctor serving a small town in Germany. He was formerly a doctor from a large hospital in one of Germany's wealthy cities but his realization that he was not the doctor he wanted to be made him decide to go to the countryside and serve a doctor-less town.

Schumann's life before moving to the village somewhat parallels what Tenma's future was expected to be like before his encounter with Johan. He lived in a large city, got in good with the director and wrote all his papers, and even got married to the director's daughter. However, he became so focused on moving up status-wise that he failed to realize his wife's liver was failing. She passed away, causing him to realize the value of human life; consequently, he decided to leave the big city and move somewhere far away where he could personally connect with all his patients.
