This book was published ten years after Dayan Aloni’s book Degel Yosef (about which I have written before). It is a book about mikvaos (ritual baths), printed by C. George in London. The book has a haskamah (approbation) from Rabbi Isaac Halevi Herzog, who had been the Chief Rabbi of Ireland and was then appointed Chief Rabbi of Palestine and then Israel. It would have been one of the last haskamos that he wrote, as he died in the year of publication.
The book also has an In ‘Memoriam’ page, listing eight people in Hebrew and English; presumably people who donated to the printing expense.
Rabbi Schneur Zalman Yosef Aloni (Dubow) was born in Penza (some sources say Riga) in western Russia, in 1915. His father, Rabbi Yitzchok Dubov, emigrated to England and became a teacher at Manchester Yeshiva. Rabbi Aloni was educated at Mir, Grodno Yeshiva under Rabbi Shimon Shkop, and in 1935 was at the Hebron Yeshiva in Palestine. He received semicha (his rabbinical degree) from Chief Rabbi Isaac Herzog.
In 1939 Rabbi Aloni emigrated to Dublin and married Sarah Leah (Lily), the daughter of Rabbi Michael Osher Matlin of Dublin, in 1940. He was Rav of the Beit Hamedrash Hagadol in Walworth Road, Dublin, which is now the Irish Jewish Museum. He was head of the Dublin Beis Din (rabbinical court) from the mid-1950s. In 1977 he became Head of the Federation of Synagogues Beth Din in London, at a time when the Federation increased the scope of its activity, particularly in kashrus supervision and licensing. He retired in 1988 and died in London following a long illness.
