The Liberal Jewish Congregation in Amsterdam was founded in 1931. Its membership increased as a result of the large numbers of Jewish refugees from Germany. So, it needed space for its services. From 1937 onward, the temple of the Theosophical Society was rented and used as a synagogue. The consecration was attended by Heinrich Stern, the chairman of the Liberal Jews in Germany.
Otto, too, was liberal Jewish and involved in the establishment of the synagogue.
