Рапопорт

 Ḥayyim b. Simḥah ha-Kohen Rapoport:
Polish rabbi, born about 1700; died in Lemberg 1771. He was rabbi in Zetel, Lithuania, about 1729, but in the following year appears as rabbi in Slutsk, in the government of Minsk; his signature, attached in that year to an approbation of R. Jehiel Heilprin's "Seder ha-Dorot," indicates that he was even then considered an authority. Ten years later he was chosen rabbi of Lemberg, a position to which his father had been chosen twenty-two years previously, but had died before he could assume the office. With R. Baer of Yazlovicz and R. Israel Ba'al Shem, in 1759 Ḥayyim, under orders from, Bishop Mikolski, held the memorable disputation with the Frankist leaders. His responsa and approbations are found in numerous contemporary works, including those of his brother-in-law Ẓebi of Halberstadt.

Ḥayyim had two sons, Aryeh Löb (d. 1759), head of the yeshibah of Lemberg, and Naḥman, rabbi of Glogau. Of his three daughters, the first was married to Joel Katzenellenbogen, a Galician rabbi; the second married Aaron ha-Levi Ettinger (d. at Lemberg c. 1759), for some time rabbi of Rzeszow, Galicia; the third became the wife of a certain Baruch b. Mendel b. Hirz. Ḥayyim ha-Kohen Rapoport of Ostrog, Volhynia, author of "Mayim Ḥayyim," responsa (Jitomir, 1858), who died in 1839, was Ḥayyim b. Simḥah's great-grandson.

Ḥayyim's works remained in manuscript for nearly a century after his death. The first, a collection of responsa entitled "She'elot u-Teshubot Rabbenu Ḥayyim Kohen," in the order of the Shulḥan 'Aruk, was publisḥed in Lemberg in 1861. The second, "Zeker Ḥayyim," sermons and funeral orations, also appeared in Lemberg, in 1866. He is said to have written several more works which are still in manuscript.
