Rabbi Todros son of Rabbi Zvi
Rabbi Todros was one of the most famous Torah scholars of the community of Rovno in the eighteenth century (about 1740–1780) and the author of the most important book “Halacha Psuka”. He was the first Rovno man who printed a religious book. The book is a compilation of all the poskim (=interpreters), ancient and recent, such as “Beit Yoseph”, the RMA (Rabbi Moshe Ben Israelish 1530–1572), the “Turey Zahav” (“The Golden Columns”, a book by Rabbi David HaLevi–Segal 1586–1667), “Siftey Cohen” (“The Lips of Cohen” by Rabbi Shabtai Ben Meir HaCohen, 1621–1662) and his own interpretations. He wrote the book to present the connections between the current laws and their origins in the Gemara and other ancient texts. This was only the first part of his general work on the four parts of the “Shulchan Aruch” (up to chapter 122) and is based on “Yoreh Deah”, Part I – the laws of ritual slaughter and other rules of Kashrut. The book was printed in Turkey in 1765, quickly became famous and the stores run out of copies in a short time.
The following important Rabbis endorsed it: Rabbi Chaim Rapaport Chief Justice of Lvov, Rabbi Yitzhak HaLevi Horowitz of Brody, Rabbi Aryeh Leib Chief Justice of Kremnitz, Rabbi Naftali Hertz Chief Justice of Dubno, Rabbi Yitzhak Isaac of Rovno, the Chief Justice of Ostraha and others. The most important of these endorsements was that of HaMagid of Mezhrich and Rovno Rabbi Dov Ber, since it was one of the very few books he had endorsed.
The descendants of Rabbi Todros used the name Rosenthal.
