Pinchas Menachem (Elazar) Justman (1848–1920)[1] The Piltzer Rebbe, also known by the title of his main work, the Siftei Tzadik was a Hasidic Rabbi who after the passing of his brother-in-law Rabbi Yehudah Aryeh Leib Alter, became a Rebbe for some Gerrer Hasidim, in Pilica, Poland.

Orphaned of his mother, he was brought up by his grandparents, Rabbi Yitzchak Meir Alter (known as the Chiddushei Harim) and his wife.

[5] Justman published the fifth printed edition of the Jerusalem Talmud, at Piotrkow from 1899 to 1903, with the commentary of Rabbi Yaakov Dovid Wilovsky (Ridbaz).

In 1905 when his brother-in-law, the second Gerrer rebbe—Rabbi Yehudah Aryeh Leib Alter died, some of the Hasidim sought to bestow the mantle of leadership upon him.

Eventually he was buried in the Jewish cemetery of Częstochowa,[4] next to his son Yitzchak Meir who died a year earlier.
