Isaac Lumbroso (1680–1752) was a chief rabbi of Tunis and rabbinical author.
Lumbroso was appointed rabbinical judge of the latter; and, being a man of means, he filled at the same time the position of receiver of taxes to the bey, as well as that of Qaid or official representative of his community.
He encouraged and generously assisted his fellow rabbis; and his reputation as a Talmudist and Kabbalist survived him.
[2] Lumbroso was the author of "Zera' Yiẓḥaḳ," published posthumously at Tunis in 1768.
Several funeral orations, pronounced by Lumbroso on diverse occasions, are appended thereto.
