With the construction of the wall in 1961, the school was robbed of one of its teachers. On August 13, 1961, Mathematics teacher Wolfgang Pache had visited West Berlin and was "walled out". He was unable to return to the GDR and did not work as a teacher again. Clothes and literature from the West were prohibited. From 1948 onwards, all directors and about 2/3 of teachers were members of the SED. At that time this was an exception because the GDR leadership targeted a 100% membership of the teachers in the SED.
