In 1786, only 13 years old (This needs verification, as Mahler (in Hasidim and The Jewish Enlightenment p 125) dates this to 1816. Similarly, in the Hebrew Wikipedia page, it says that Perl married at 14 and had a positive interest in Hasidut), he wrote a book in German,
Ueber das Wesen der Sekte Chassidim aus ihren eigenen Schriften gezogen (
On the Nature of the Sect of the Hasidim, Drawn from Their Own Writings), in which he attempted to demonstrate the absurdity of the beliefs and practices of Hasidic
rabbis, including
Rabbi Nachman of
Bratslav and
Rabbi Shneur Zalman, founder of what became the
Lubavitcher movement. His work was rejected by the imperial
censors, who apparently feared that it would create disharmony among
Austria's Jewish subjects. It was published in 1816. At the age of 14, he was engaged by his parents, but he continued living in his father's home. He studied
Kabala and
Hasidut, but his father, who was opposed to these studies, made him a merchant. This deeply affected his opinions regarding various subjects. Perl's satire of the Hasidic movement,
Revealer of Secrets (
Megalleh Temirim), is said to be the first modern novel in
Hebrew. It was published in
Vienna in 1819 under the
pseudonym "Obadiah ben Pethahiah". Structured as an
epistolary novel, it is currently in print only in an
English translation, by
Dov Taylor, published by
Westview Press. It is an unusual book in that it satirizes the language and style of early Hasidic rabbis writing in Hebrew, which was not the vernacular of the Jews of its time. To make his work available and accessible to his contemporaries, Perl translated his own work into
Yiddish. A subsequent parody of Hasidic writings,
Words of the Righteous, written with
Isaac Baer Levinsohn and published in 1830, is available in Hebrew. ==Educator and informer==
