Salomon and Joseph Ottenheimer founded the weaving mill for cotton & linen in Jebenhausen in 1862. In 1865, the brothers moved their business to Göppingen. After Salomon Ottenheimer left in 1902, Max Ottenheimer, son of Joseph Ottenheimer, joined as a partner. In 1905, a second factory was built in Kleinsüßen and the main office was moved there; a branch office was established in Göppingen. The company changed its name to "Mechanische Weberei Süßen, Gebrüder Ottenheimer, Göppingen und Süßen".

The cemetery was founded in 1752 by the purchase of a plot of land "An den weißen Bergen" by three Schutzjuden of Bleckede named in the purchase deed, Emanuel Hertz, Salomon Mosis and Benjamin David. In 1802, the cemetery was expanded to its present size by another land purchase. A death list exists for the period from 1789 to 1935.

Community life and school reform: The Bleckede synagogue community, which was founded in 1844 and to which Dahlenburg and later Hitzacker also belonged, was housed here and used the upper floor as a prayer room. This was also the birthplace of the reform pedagogue Dr. Kurt Löwenstein (1885-1939). A member of the Reichstag since 1920 and head of municipal education in Berlin, Löwenstein advocated school fees based on income, expansion of school lunches and workers' baccalaureate courses. In 1933 he emigrated to France, where he succumbed to a heart attack in May 1939.
