The 1914 Upper Silesia business address book (p.141) names the widow Bertha Ollendorf geb. Danziger as the owner of Albert Danziger's Konditorei. An article in a Katowice newspaper names a Julius Allendorf (sic) in connection with Albert Danziger's Konditorei. Albert's daughter Bertha married an Ollendorff. I asume that the Julius Allendorf was actually Julius Ollendorf, and that this was Bertha's husband.

His gravestone stands in the Jewish cemetery in Katowice.
