R. Joseph Moses Ben David Breslau, (1691–1752), German rabbinical scholar apparently born in the city of that name. Breslau studied under R. Abraham Broda, whose daughter he married. He served as rabbi in Krefeld and, from 1743 until his death, in Bamberg. In addition to Shoresh Yosef, R. Breslau was also the author of Hok Yosef (1730), on the laws of Passover, comprising novellae on the Orah Hayyim sections of the Shulhan Arukh (429–94). In it Breslau criticizes the Hok Ya'akov of Jacob Reischer. The two books were published together under the title Hukkim Tovim (1767). Reischer wrote a reply entitled Lo Hibbit Ayen be-Ya'akov, which was published in the 1814 edition of Hukkim Tovim; (3) Ketonet Yosef, sermons, published by his son, Abraham of Muehlhausen, as an appendix to the Toledot Avraham (1769) of Broda. His glosses on Orah Hayyim and on Yoreh De'ah as well as responsa remain in manuscript.
