Here is an obituary for Chacham Isaac Bernays (1792-1849):
In case you are wondering at the name "Ettlingen," seeing as how the aforementioned rabbi is normally known as Ettlinger, a quote from the very first page of text of Dr. Judith Bleich's dissertation on him is in order:
"In his youth he signed his name Yukov Ettlingen, Yukov being an affectionate cognomen for Ya' akov (Jacob) and Ettlingen, the name of the small town in which his forebears had at one time resided and from which the family surname was probably derived. It is in this form that his name appears in his first published work, Bikkurei Ya'akov [Altona, 1836]."She further reveals that critics of Bernays challenged the fact that he had received rabbinic ordination. In an article in the Allgemeine Zeitung des Judentums of February 26, 1842 an anonymous correspondent relates that in the 1820s "a satiric limerick regarding Bernays mocked his usage of the title Hakham rather than Chochom in light of the fact that Bernays had neither adopted the Sephardic pronunciation nor had he received rabbinic ordination.
Here is that piece:
Note: Bernays had in fact received semicha from Rabbi Abraham Bing, same as Rabbi Ettlinger. Bleich notes that Bernays was recommended for his rabbinic post in Hamburg by Rabbi Bing, and in addition he served as dayyan in Wuerzburg during Bing's incumbency. Thus, the charges that he never received ordination must be pure fabrication, although there is no documentary proof of his ordination extant.
The issue itself reminds me of another one which occurred only a decade later in the United States. In the 1850s a bitter war of words raged between American Reform Rabbi Isaac Mayer Wise and indefatigable and archetypal spokesman and teacher of American Orthodoxy, the Reverend Isaac Leeser. Wise "smeared" Leeser as never having been ordained. Leeser, however, had never claimed to be ordained, and freely admitted that he wasn't. However, he countered, Wise claims to have been ordained by Prague's Chief Rabbi Solomon Judah Loeb Rapoport. Where was Wise's certificate of ordination? Wise never did, and maybe never could, produce it.
