Aryeh Leib Heller

Aryeh Leib HaCohen Heller (c. 1745 – 1812) (Hebrew: אריה לייב בן יוסף הכהן הלר) was a Rabbi, Talmudist, and Halachist in Galicia.

In his youth, after being recognized by his father as a prodigy, Heller was sent to learn Torah from Rabbi Meshulam Igra of Tysmienica, Poland, an outstanding authority.

He had four children: a daughter, Franziska Freide (1788–1842), who married Solomon Judah Loeb Rapoport (Shi'r) in 1810, and three sons: Yosef (1769–1832), David (1771–1830), and Zwi Hirsch (1776–1834).

Rabbi Heller's works became widely disseminated throughout Europe at a time when, due to technical and financial reasons, this kind of recognition was rare.

Many kohanim today claim to be descendants of Leib Heller's family, including the current Toldos Aharon Rebbe, but proof is difficult to establish without proper lineage data.
