This stunning large architectural drawing shows a double spiral staircase, most probably planned for a larger object, such as a library or a town-hall. A pair of spirale staircases leading directly to the second floor is decorated with neo-gothic ornaments.
The draft is signed by Heinrich Quiring (1854–1927), a director and project manager of an iron foundry in (Märkische Eisengießerei) in Eberswalde, north-east of Berlin. The foundry was founded in 1890 by Fedor Friedeberg and was responsible for casting metal parts for large constructions such as metal parts for buildings, bridges, sewer systems, and railways, as well as decorative architectural details such as fences, benches, and stairs. Metal parts on this plan for a staircase had to include fences, pillars and gothic ornaments.
Heinrich Quiring was father of Heinrich Quiring (1883 – 1964), a German paleontologist and geologist.
