Johann Martin Luther Sulzer was the son of Constanzia Turettini and stepson of Marco Garb. Garb sent Luther to Grantville as a spy. However, it was soon clear that Martin didn't have the guile to successfully obtain the information that Marco needed. Instead, he became a science teacher at Grantville High School.

Sulzer's half-sister Constanzia Garb and his cousin Catharina Sulzer were then sent by Garb as spies themselves. Sulzer helped his sister and cousin gain teaching positions in the high school. Despite being Constanzia's brother, Martin saw himself as another father. In this role, Martin learned of Constanzia's infatuation with with rising Pentecostal minister Dieter Fischer, and informed his stepfather. Sulzer didn't approve of Fischer and his faith, believing Pentacostalism was a mere fraud.
