His name appears in Berliner Schachführer 1931, a small Yearbook of Berlin chess edited by Kurt Richter. His address was Fichtestr. 16, Berlin.
That address is shown for Edmund Nebermann in the 1930 Berlin Address Book.
It was still his address at the time of his death in 1946, March 2. His Berlin death record shows that he was born 26 December 1878 in Berlin.
