Moses Meïr Perls, for many years Wertheimer's secretary and almoner, mentions him in his "Megillat Sefer" (1709) as "a rabbi of great congregations in Israel." In some works Wertheimer is called "rabbi of Prague and Bohemia"; but he did not accept this title, as may be seen in an edition of Alfasi (Frankfurt-am-Main, 1699–1700). His reputation spread even to the Orient, where he was described as a "prince of the Holy Land" and given the title of "rabbi of Hebron and Safed". His native city also honored him with the title of rabbi. Many authors sought his "approbation", but only in a few cases did he give it, e.g., in Moses ben Menahem's Va-Yachal Mosheh, and Rabbi Yair Bacharach's "Chavath Yair." He contributed liberally toward the publication of such works as "Chavath Yair" (in which his name appears with that of Samuel Oppenheimer), Rabbi Yehudah ben Nisan's "Beth Yehudah", Rabbi Gershon Ashkenazi's "Avodath ha-Gershuni" and "Tif'ereth ha-Gershuni" (in which David Oppenheimer also is mentioned). He and his son-in-law Moses Kann bore the greater part of the expense of printing the Babylonian Talmud in Frankfurt-am-Main in 1712-22; this excellent edition was confiscated and for thirty years kept under lock and key (see Kann, Moses).
