Nazism Turns the House into an Instrument

This flow follows the conversion of the Landauer home into a centre for racial science and exposes the violence concealed by scientific language.

The Confiscation

Property and Power Seizure The authorities take the Landauer House from its Jewish owners. The confiscation is framed in official language, but its practical meaning is the removal of a family’s property without meaningful recourse. The loss makes clear that the law has become an instrument of persecution. A new institution The house is assigned to a racial research office. Its transformation links private dispossession to the Nazi state’s wider program of classification and control.

The Researchers Arrive

Science in Service of Ideology A professional performance Researchers arrive from German and local institutions, presenting themselves as pioneers of scientific discovery. Werner Stahl insists that they must behave as scientists and treat subjects respectfully. His language of professional standards gives the work an appearance of restraint. Equipment and purpose Scales, callipers, cameras, and Hollerith machines turn the Glass Room into a system for collecting and sorting human data. The institution’s methods make prejudice appear measurable.

People Become Records

The Human Subject The examination process Visitors provide information about origin, language, religion, health, and family history, then submit to physical measurements and photographs. The staff describes the procedure as confidential and painless. The calm routine conceals the subjects’ lack of control over how the collected data may be used. False objectivity Measurements record real bodies but cannot justify the racial judgments imposed on them. The centre’s precision lends authority to categories that are ideological rather than scientifically sound.

Heydrich Demands Results

Power Tests the Laboratory The inspection Reinhard Heydrich visits the centre and asks whether researchers can identify Jews and distinguish Slavs from Germans. Stahl explains that no single physical trait provides a reliable answer. The visitor treats scientific uncertainty as an obstacle to state policy rather than a reason to question the categories. The limits of the project Heydrich’s interest in the measurements exposes the intended political use of the research. The centre is not an isolated scientific experiment; it serves a regime demanding racial classifications.

A System Without a Truth

Classification Continues Data processed The centre sends punched cards to Berlin, where machines sort records in search of patterns. The scale of the operation suggests that bureaucratic accumulation can make an invalid theory appear comprehensive. The people represented in the files become statistical material, their individual lives reduced to fields and measurements. Closure and legacy The centre eventually closes because the research fails to provide the clear racial distinction officials want. Its failure does not undo the persecution that the institution helped normalize.
