HB-Werkstätten für Keramik

HB-Werkstätten für Keramik GmbH (HB Workshops for Ceramics) in the Brandenburg district of Marwitz was founded by Hedwig Bollhagen (1907–2001) and Heinrich Schild (1895–1978).

[3] As had been the case for Margarete Heymann and the two employees mentioned above, the master craftswoman ceramicist Thoma Gräfin Grote, who was a developer and commercial assistant in the company from 1934/1935 onwards, had been trained by Gerhard Marcks in the ceramics workshop of the state-run Bauhaus on the Dornburg.

[4] He opened up the field of building ceramics and at the same time brought with him industrial experience in the development of decoration which he had gained at the United Lausitz Glassworks (Wilhelm Wagenfeld).

After the war, Heinrich Schild, who was a member of the National Socialist German Workers' Party, fled to West Germany.

[6] In terms of setting up and profiting from the HB workshops, at least two Jewish ceramicists were involved, at least up until the end of 1936, these being Margarete Heymann and Nora Herz from Cologne.
