Part 3 of the Mareh Kohen series. The content is entirely original, although it relates to material covered in the first 2 parts in the series (Pt 1 - 1919, Pt 2 - 1928), including the controversy generated in the late 1920s by the notorious Rabbi Joseph Shapotshnick's dispensations for agunot to remarry without chalitza or a get, in which R. Adler took a prominent part.

R. Shemariah Manasseh ha-Kohen Adler (1874-1959) was a brilliant Talmudic scholar and the author of numerous rabbinic works, most of which were polemical in content. Originally from Poland, he hailed from the distinguished Adler family whose members included Rabbi Nathan ha-Kohen Adler, mentor of the Chatam Sofer, and also Chief Rabbis Nathan and Hermann Adler of London. In 1915, after a short and unsuccessful stay in Germany, Adler moved to England with his family where he quickly became a part of the small but thriving ultra-Orthodox community that was concentrated in London's East End. During the period of the First World War Adler became acquainted with R. Abraham Isaac ha-Kohen Kook, who was stuck in London as a result of being unable to return to Palestine. They became very close friends, and Adler wrote a commentary on R. Kook's sole London publication, the kabbalistic work Rosh Millin.

During this period R. Adler was briefly thrown into jail as an illegal immigrant, although he was convinced that his arrest had been orchestrated by the head of the Chief Rabbi's Beth Din, R. Samuel Isaac Hillman. Whether this was true or not, it was the catalyst for R. Adler's unrelenting campaign of vitriol against R. Hillman and the community establishment that was to last for decades. Over the years that followed R. Adler published book after book that scrutinized and criticized every aspect of Britain's Jewish communal life, and he was a strident critic of the rabbinic leadership and the level of observance even among those who considered themselves ultra-Orthodox. Often R. Adler would involve European luminaries with whom he was acquainted, and in particular he corresponded frequently and amicably with R. Joseph Rosin of Dvinsk - the 'Rogatchover' - whom he held in the highest esteem.

After World War Two, estranged from both the community and his family, R. Adler moved to a boarding house in Dorking, outside London. The proprietor, Rabbi Dr. Hayyim Kohn, was a bibliophile with an enormous library and there R. Adler immersed himself in learning and writing, producing numerous books that challenged hitherto accepted communal practices. During his latter years R. Adler became a hermit, rarely venturing from his room and often refusing to attend Sabbath services even if he was needed to make up a quorum. From Dorking R. Adler moved to Westcliff, and finally to Brighton, where he died in 1959. He is buried in Israel.
