Thanks for the info.
As to asking for the specific dates.... I had assumed the name had changed sometime between 1933 and 1936 and that the end date would have been towards the end of the war, but I wasn't sure which year (perhaps 1934 or 1935 to start or 1944 or 1946 to end depending on how quickly name changes could be processed. Today, the renaming of a street can be a very politically charged process depending on the street, the person commemorated and can take years).
Do you (by any small chance) happen to know if there are any pre-war residential dwellings left on this street? Google maps makes it a challenge to get an idea of what is there today, though it appears to be larger commercial buildings or apartment complexes. (approx. address 97 Alleestraße).
Once again, thank you for taking the time to answer despite the fairly logical answer.
