Gesetz zur Wiederherstellung des Berufsbeamtentums
In 1933 Adolf Hitler passed the Law for the Restoration of the Professional Civil Service, which applied to non-Aryans. Later a similar law was passed to cover all lawyers, doctors and other professions. Kosterlitz, who had Jewish ancestry, contacted John Macleod, FRS in Aberdeen, who managed to accumulate some modest funding, sufficient for him to reply ‘come to Aberdeen … but no guarantee of a secure job’. Kosterlitz arrived the following March.
