The main portion was used as a German military hospital called Lazarett zum Heiligen Geist.

[4] On 2 September 1946 the building at Am Bornheimer Hang 46 was vacated in order to be used as the Community High School.

Frankfurt, along with Berlin, Bremen (Bremerhaven), Heidelberg, Munich and Erlangen (Nürnberg), were the first American high schools to open in the European Theater between September and October 1946.

In the fall of 1954, the school moved to a newly constructed set of buildings on Siolistraße at Miquelallee, near the I.G.

A dormitory was located adjacent to the school to house students whose families lived too far away to commute daily.

Dormitory students (Dormies) included those residing only during the school week, five days, and those who lived so far away that they only went home on long holidays.

In earlier days, dorm life was very structured and included a mandatory two hour study period each night.

The door was left open so that the adult monitors could see that each student was present and a minimum of distraction was adhered to.

The Abrams Complex was returned to the German Federal government and the school was transferred to the Philipp-Holzmann-Schule.
