[2] Hilchos Rotzeach U’Shmiras Hanefesh, 13:1. We know of the Shabsai Frankel editions of the Rambam which has helped tremendously with the learning of the Rambam. R’ Shabsai Frankel (1909-2000) was a successful philanthropist and publisher of Torah books. His father, R’ Yosef Frankel, was a prominent Gerrer Chassid in Poland whose son Alexander married a granddaughter of the Gerrer Rebbe, the Imrei Emes. R’ Shabsai married the daughter of R’ Yosef Nechemya Kornitzer, a great-grandson of the Chassam Sofer and the Chief Rabbinical Justice in Krakow. During World War 2, R’ Shabsai fled Poland for Vilna and then he eventually immigrated to The United States. In America, R’ Shabsai joined with the likes of R’ Reuven Grozovsky in helping save European Jews from the Holocaust. In 1970, after succeeding in business, R’ Shabsai moved to Eretz Yisrael to fulfill his lifelong dream: He wished to publish a new, corrected edition of the Rambam’s Mishna Torah. R’ Shabsai established a Kollel—which he funded from his own money—of select Talmudic scholars who would actually put together the new print of the Rambams’ works as well as a comprehensive index of various other rabbinical commentaries and citations who dealt with Rambam’s rulings. The first volume was printed in 1973 and the last was finished in 2007.
