All his children were born in Cosel. An Adolf Apt is mentioned in www.zydzikozielscy.pl as a senior member of the "Chevra Kadischa" in Cosel in the late 19th century.



When he witnessed Friedrich's and Fedor Max's marriages in 1918 and 1919 his address was in Berlin, Charlottenburg, as it was also when his son Bruno married in 1914. An Adolf Apt, Privatier, is listed in the Berlin address books at Charlottenburg, Leonhardtstrasse 2 for many years up to and including the 1928 edition, and Adolf's death certificate gives the same address. MT notes that his wife died in Charlottenburg.

His gravestone is one of three, originating from Cosel Jewish cemetery, which were discovered in a workshop in Rybnik in July 2018. Another of the three ex-Cosel gravestones was that of Henriette Schlesinger geb. Gassmann (1848 - 1886).

Adolf's gravestone confirms that he died in Charlottenburg in 1927.
