Yosef Perl was a satirist, and is often described as a maskil. A vigorous opponent of hasidim in particular, he was active in the middle of the 19th century when the stories of Rebbe Nachman and Shivchei haBesht were first published. His most famous work is Megaleh Temirin (1819), which he published under a pseudonym.
His first satirical work was not published during his lifetime, and I've been unable to even find what it was called. It was a parody of Rebbe Nachman's stories, written in the same style (in a combination of Hebrew and Yiddish), providing a comic conclusion to one story that ended suddenly in the original, and inventing another story from whole cloth. Perl's style in all of his writings was to ridicule hasidim by way of imitation, and I would very much like to see an example of this.
If anybody here is familiar with maskilic literature and could recommend to me where I might find more information about Yosef Perl, that would be great. Ideally, I would love to see a copy of this particular text (his parody of Rebbe Nachman's stories). I understand that it's almost certainly not for sale, but if there is a published version in a library somewhere, I should be able to get it through an interlibrary loan. (And, if not, maybe one day take a vacation...)
From what I understand, Perl had a negligible impact upon the subsequent history of maskilic literature. He was a frum Jew, and is probably better classed together with misnagdim than maskilim, but for the fact that he also published in German and availed himself of the writings of other wordly, cosmopolitan Jews (like Menachem Mendel Lefin, for example).
