sentences:  Some congregants formed a registered association for the Rykestraße Synagogue (Synagogenverein Rykestraße), promoting strong company among the congregants, organising meetings, festivities, lectures to this end, cherishing Jewish traditions and collecting and donating money for needy congregants (Tzedakah), but also demanding a say at employing rabbis and cantors.In 1931 Hugo Alexander presided over the association.In January 1933 Sally Heilbrunn, (1869–1951, Tel Aviv) and Rabbi Moritz Freier gathered 300 people protesting the replacement of Michael Sachs' Rödelheim siddur (Siddur Sefat Emet סדור ספת אמת) and machzor by the Berlin unitary siddur and machzor (Einheitsgebetsbuch).
