Primary school classes were held in various residences in the German community. - 1947: In 1947, Dr. Fritz Müller, the school’s director since 1938, founded a private school under the neutral name of Colegio Andino with the support of Mr. Reinhard Kling.
- 1948: In 1948, the Colombian Government returned the German School’s assets to the Deutscher Schulverein. Schulverein members regrouped and changed their name to the Alejandro von Humboldt Cultural Corporation, which took over the new school’s management. Under Mr. Pablo Bickenbach’s presidency, this organization’s board of directors sold the assets of the old German School on Calle 20. It developed the project to build a modern large-scale school on Carrera 11 and Calle 82.
