Archival Preservation of the Schulz, Knaud & Co. Records
The business records of Schulz, Knaud & Co., a historical firm based in Essen, Germany, represent a significant collection for industrial and economic historians. These documents, currently held within the Landesarchiv Nordrhein-Westfalen, provide a detailed look at the operational history of the company. Archivists have organized these materials into subseries to ensure that digital objects and physical records remain accessible for researchers studying the industrial development of the Ruhr region.
Structure and Classification of the Collection
The collection is managed through a hierarchical system of description, which is standard practice for German state archives. According to the Archive Portal-D, the records are classified by their original context, allowing historians to trace the evolution of the firm’s administrative and commercial activities. The “digital objects” designation within the archive indicates that select portions of the paper records have been scanned or digitized, enabling remote access for scholars who cannot visit the Essen or Duisburg locations in person.
The classification includes:
- Identification: A unique archival reference code assigned to each document or folder to ensure precise retrieval.
- Level of Description: A metadata framework that categorizes items from the individual document level up to the broader subseries.
- Subseries: Groupings of records that share a common functional purpose, such as accounting, correspondence, or legal documentation.
Historical Context of Essen Industry
The presence of the Schulz, Knaud & Co. archives in Essen is reflective of the city’s role as a powerhouse of the German industrial revolution. Essen served as the hub for the coal and steel industries, and the records of local firms are essential for understanding the transition from mid-19th-century trade to large-scale industrial manufacturing. The Landesarchiv Nordrhein-Westfalen maintains these records to document the economic shifts that defined the North Rhine-Westphalia region.

Accessing Digital and Physical Records
Researchers interested in the Schulz, Knaud & Co. materials must navigate the Archive Portal-D, which acts as the centralized gateway for state archives in the region. While some records are available as digital objects, many remain in physical form and require an appointment at the reading room.
