The history of IBM in Germany dates back to 1910, with the founding of DEHOMAG (Deutsche Hollerith-Maschinen Gesellschaft mbH) in Berlin. The company was renamed IBM Deutschland GmbH in 1949, when it relocated to Böblingen.
The D 11 tabulator, which was manufactured from 1935 onwards, was the first German machine of its kind. Used for punched card analysis, its ability to read, count, compute and print cards made it the mainstay of many so-called Hollerith departments.
The machine proved a milestone in the development of punched card technology: It was produced until 1945 and on sale until 1960, latterly as the IBM D 11 Type 450.
Around 1,100 D 11 models were sold in all.
Date of manufacture: about 1936
