["Hereditary and racial welfare" in public health services: support and selection].

The long-term aim for the German public health service during National Socialism was a hereditary and racial welfare. Several following legal regulations contributed to the implementation of a specific national socialist population policy on the basis of racial hygiene and gave immense power to health officers. Especially with the Law for the Prevention of Hereditarily Sick Offspring, compulsory sterilisation was legalised and caused about 400,000 victims up to 1945. The central force in this new system was the public health office. The work of two health officers in neighbouring offices in upper Bavaria is compared. Results show that health officers had a large flexibility in their individual estimation. The restrictive interpretation of their duties did not necessarily cause any sanctions by the superior authority.
