Moshe Teitelbaum (Ujhel)

According to Leopold Löw, he signed his name "Tamar", this being the Hebrew equivalent of Teitelbaum, which is the Yiddish for "date palm" (compare German "Dattelbaum").

In 1822 Teitelbaum was suspected of having supplied amulets to certain Jewish culprits who had been cast into prison for libel, in order to assist them in escaping.

When called upon to vindicate himself he declared that the amulets in question served only as substitutes for the mezuzah and that their only purpose was to protect their bearers against demons.

He originally wrote a significant portion of his commentary on Psalms on the backs of personal notes handed to him by petitioners seeking his aid and blessing.

These notes were transmitted via a succession of prominent hasidic rabbis, until finally being edited and published for the first time in Kraków in 1880.
