The Sankt-Ansgar-Schule (common abbreviation: SAS) is a private secondary school in Hamburg, Germany. It was founded in 1946 as the only boys' school by the Society of Jesus, an order of the Catholic Church, in the State of Hamburg. The school was named after Saint Ansgar who christianized Northern Germany in the 9th century. The motto of the SAS is: bonitatem et disciplinam et scientiam doce me, domine which is engraved above the official main entrance. In 1978, it became a co-educational school. The Jesuits gave up running the school in 1993 themselves but the Sankt-Ansgar-Schule has remained a member of the association of Jesuit schools and still follows all of the order's rules for their educational institutions. Currently, the archbishopric of Hamburg formerly runs the school.
