His Jewish first name was Shmuel. He authored the volume Emunes yisroel, a religyes moralishes bukh, gezamelt oys den hebreishen shriftshteler (The faith of Israel, a religious, moralistic book, compiled by a Hebrew writer) (Prague, 1823), 104 pp. The book has an educational character about it. The author taught Jewish children good manners: to go in the way of justice, not to do bad things, and preserve their Jewishness. The language of the book is heavily Germanized. The author probably had his readers in mind, for whom Eastern European Yiddish would have been strange, or it was fine for them to speak among themselves, but not for reading and all the more so for studying proper behavior.
