By Royal Decree of 26 February 1814 and at the initiative of King William I, the Nederlands-Israëlitisch Seminarium [Dutch-Jewish seminary] (NIS) was opened in Amsterdam to provide the Jewish communities with rabbis, teachers and other officials. Benjamin Gans was one of the students.

Benjamin Gans married Debora Kleinkramer in 1943. The civil ceremony was performed at the Hollandsche Schouwburg, as Jews were no longer allowed to get married in the city hall.
