After World War I, Glöckner earned some money with the copying of paintings for the Gemäldegalerie Alte Meister.
Glöckner lost his home during the bombing of Dresden in World War II and moved to Loschwitz.
Because of his formalist style, the officials of the GDR refused him the appreciation he deserved for a long time.
Centrally in the area of the Technische Universität Dresden he was allowed to erect a sculpture, which had been banned just a few years before.
