Shabsai Frankel (August 13, 1909 – September 30, 2000) was a rabbi, businessman, philanthropist, and publisher of Torah books.
During World War II, Rabbi Shabsai fled Poland for Vilna, Lithuania.
In 1970, after succeeding in business, Rabbi Shabsai moved to Israel to fulfill his lifelong dream: He wished to publish a new, corrected edition of the Rambam's Mishneh Torah.
Nonetheless, when Rabbi Frankel took a break from printing his edition of Maimonides' works and instead invested in comprehensive indices from the tractates Bava Kamma and Bava Basra, he died on Rosh Hashana, 2000, at the age of 91.
[2] His index on Bava Basra was printed after his death and was named in his memory "Raza D'Shabsai".
