This is the "dataverse" of the Lippe brick-makers project, conducted by researchers Jan Lucassen ([]( and Piet Lourens

Background about the Lippe project

"In the 19th century, up to 40% of all male workers left the Principality of Lippe every spring. Until the fall, they worked in brick works in northern Germany, the Netherlands, Scandinavia and Eastern Europe. The seasonal migrant work of the Lippe brick-makers dates back to the 17th century. The administration of the Principality of Lippe recorded them in detail. For the years from 1778 to 1869, the State Archives of North Rhine-Westphalia (LAV NRW), Department of East Westphalia-Lippe, in Detmold holds over 100,000 records on more than 30,000 brick-makers. Nowhere else in the world is it possible to find so much detailed information on seasonal workers with their origins and destinations for such a long and early period. They are invaluable for the history of migrations, work and family, but also for genealogists with ancestors from Lippe. Thanks to the cooperation between the International Institute of Social History in Amsterdam (IISG) and the LAV NRW, this data is made available embedded in its historical context."

Origins and structure of the data

This project "dataverse" contains three "datasets":
  1. "Lippe brick-makers project: archival pages transcriptions": Lucassen and Lourens transcribed manually a great part of the scanned pages from the Lippe archive. This dataset contains the files with the transcriptions and a link to each digital scan.
  2. "Lippe brick-makers database": Lucassen and Lourens extracted data from the archival scans corresponding to people and the places, factories they went to work to, and other details. This dataset contains the files with the extracted data.
  3. "Lippe brick-makers database: sample with geodata" This dataset contains the files from a sample of the database which were enriched with geodata.

  4. More information about the Lippische Ziegler project can be found here:
