Two printed pamphlets about the polemic of the eruv in Frankfurt am Main:
· Porat Yosef, pamphlet about setting up an eruv in Frankfurt am Main, by Rabbi Nechemya Zvi Nobel. Frankfurt am Main, 1914.
· Divrei Shalom V'Emet, by Rabbi Yisrael Avraham Aba Krieger. Frankfurt am Main, 1922.
Porat Yosef was written by Rabbi Nechemya Zvi Nobel, Av Beit Din of Frankfurt, with a long halachic responsum to validate the eruv installed around the city. Rabbi Shlomo Zalman Breuer, son-in-law of Rabbi Shimshon Refael Hirsh and his successor as Rabbi of Frankfurt, invalidated the eruv. In response, Rabbi Yisrael Avraham Krieger, by request of Dayan Rabbi Ya'akov Posen, wrote the pamphlet Divrei Shalom V'Emet, in which he endorses the eruv and opposes Rabbi Breuer's invalidation.
